lampufilamen tidak menyala. Ketika dicek tegangan heater tidak ada sama sekali alias 0v.. Owalah ternyata ini penyebab tv ini layarnya gelap. Heater pada tv digitec ini tidak menggunakan resistor pembatas. Kemungkinaan memang tegangan pada output kaki flyback tidak ada tegangan. Fikirku kali ini pasti mengganti flyback.
Home > Kerusakan > Penyebab TV Tidak Mau Hidup Rusak Lampu standby TV tidak nyala Televisi rusak tidak mau hidup saat tombol power di tekan bukanlah perkara baru, seringkali kita mengalami kerusakan Tv tidak bisa nyala tapi lampu power hidup dan beberapa kasus seperti ini pada pesawat tv di rumah, bahkan menyebabkan banyak masalah sehingga harus membawanya ke tukang servis. Dalam tulisan kali ini kita akan mengupas tuntas mengenai kerusakan televisi dengan gejala lampu standby tv tidak mau menyala, karena ternyata bukan hanya kerusakan sepele namun menyebabkan masalah serius sehingga segala hal akan mempengaruhi cara pandang akan sesuatu yang selama ini dialami. Service TV Mati Tidak Bisa Dihidupkan Service TV merek Sharp biasanya lumayan susah, paling tidak memakan waktu lama untuk menemukan solusinya. Tapi tidak untuk service TV Sharp yang satu ini, kemarin saya mendapat servisan TV Sharp 14 inch dengan kerusakan mati/ tidak keluar gambar pada layar CRT. Sedangkan lampu indikator masih manyala merah, menandakan power supply masih bekerja. Saat melihat sekilas saya curiga, wah jangan-jangan bikin kepala pusing kerusakan yang kayak gini. Penasaran kemudian saya minta remot dari si pemilk TVnya, karena siapa tau dengan mengutak-atik remote control nanti masih bisa membantu. Ternyata sama saja, malah remote controlnya sudah bukan yang aslinya. Tapi sudah menggunakan remote multi fungsi yang kebanyakan dijual dipasaran, jadinya ada beberapa tombol remote yang tidak berfungsi dengan semestinya. Solusi Akhir TV Standby Habis meneliti remote, saya beralih ke TV, langkah awal saya tekan tombol menu dan program channel -/+ pada panel depannya. Ternyata TV mau menyala normal, jadi setelah ditekan tombol pemindah channel tadi posisi stand by sudah dapat bertukar menjadi ON. Hmm.., ternyata kerusakannya Cuma karena kesalahfahaman pemakainya. Hal ini bisa terjadi mungkin karena remote control yang sudah ditukar tadi, jadi saat memencet remote mungkin keliru mengaktifkan timer pada remote, yang akan membuat TV mati secara otomatis dalam beberapa saat. Kayaknya ini adalah service TV paling mudah yang pernah saya kerjakan. Demikian pengalaman tak terduga mengenai reparasi tv yang ternyata masalah kerusakan sepele namun tidak pernah dibayangkan sebelumnya. Tulisan ini merupakan artikel pindahan dari blog lama saya yang sudah tidak aktif lagi.

Your smart TV can be under harsh conditions inside your house that you may not be aware of, which can lead to overheating. Like most electronics that are used for long periods of time, Smart TVs do overheat. This comes from many different factors, such as their coolant system built-in, the surrounding environment, and other sources of heat such as direct sunlight, heaters, fireplaces, or other electronics. Here are some things you need to know about your smart TV environment. Do Smart TVs Overheat?Do Smart TVs Overheat?Why Does my Flat-Screen TV Get so Hot?1. It has Clogged Vents2.

Smart TVs, like any other electronic device, can overheat. While manufacturers explicitly state what users should do to avoid any issues, instances of overheating still happen, despite all precautionary measures taken. Awareness of overheating is crucial as misuse leads to permanent damage to your TV. Why Does my Flat-Screen TV Get so Hot? Several factors affect the operating temperature of your smart TV. 1. It has Clogged Vents Your smart TV has ventilation holes that ensure a smooth flow of air inside the TV. The clogging occurs when dust accumulates inside, or there is not enough room for air to blow inside these vents. 2. Inefficient Airflow Even if your smart TV is regularly dusted or cleaned, if your smart TV is in a place with little to no room for air to flow, then it will overheat. 3. Heat Sources are Surrounding the TV Is your smart TV near the heater or your stove? Is it beside the refrigerator? Or is it by your window, along the way of direct sunlight? These heat sources contribute to the overheating of smart TV. Even if you have adequate cooling, if it is near heat sources, it will be prone to overheating. How Do I Know if my Smart TV is Overheating? The most common symptom of overheating is the TV being too hot to touch. Another symptom of overheating is a sudden shut down of your TV. Should you encounter this, give your TV a break of 30 minutes before operating once again. If it persists, then bring it to a qualified repair center. Do Smart TVs Have Heatsinks? Just like your computer, smart TVs have heatsinks to help it maintain a particular temperature range. A heatsink is a device that transfers heat from your electronics to air or liquid coolants in order to keep your device cool and to prevent overheating. A heatsink is common in most devices. How Do I Stop my TV From Overheating? You can try these solutions to help your smart TV perform at lower temperatures 1. Keep Vents Clear You should always dust-off your TV. Make sure accumulated particles do not obstruct the vent. If you have a small vacuum cleaner with low power, you can use it to suck out other particles through the vents. You must use minimal power to avoid damaging components inside the TV. 2. Remove Airflow Obstructions around the TV There should be nothing blocking the flow of air to the ventilation slots of your TV. That means you must position your TV in a manner that allows it to breathe freely, and away from tight spots that enclose and restrict airflow from entering your smart TV. Look at the position of your smart TV now. Is it in an entertainment console with enough room for air to flow? If you think there is not enough room or air to flow in your smart TV, consider using a more open console or use a wall mount system. If you can, have a small fan blowing air in the direction of your smart TV or around a very hot room. 3. Stay away from sources of heat Make sure your smart TV is far from sources of heat. Have a TV near your heater or near your induction stove or microwave oven? The heat from these devices has the potential to damage your smart TV. If you placed your TV by the window, where sunlight shines directly on it, you should move it somewhere else so the heat of the sun can’t touch it. 4. Seek After-sales Support If you have done the tips above and your TV is still overheating, you should consider seeking after-sales support from the manufacturer of your smart TV. They are in the best position to help you resolve any issues, and verify if there are overheating issues associated with your smart TV. They can check if there is a recall for your smart TV due to overheating or other reliability issues, and will let you know if there is a potential hazard to your or your TV’s health. Make sure that you have the model number and the serial number of your smart TV for reference of support agent who will handle your concerns. How Long Does it Take for a TV to Cool Down? You should set your TV to rest and go to its usual temperature for at least 30 minutes. You should not use it during this rest period, so the temperature can stabilize. Do the same also, if your smart TV gets exposed to extremely cold temperatures. Can TVs Catch Fire from Overheating? The United States Consumer Product Safety Commissions keeps track of all fire incidents involving TVs since 1992. While it is possible for a TV to catch fire from overheating, it is not very likely and is a rare occurrence. If you place your TV next to hot objects, such as a fireplace, or dump water on it while it is plugged in, you could catch it on fire. Do not do this! If you are careful and the TV hasn’t been recalled for fire reasons, you should be fine. Should a TV Screen Get Hot? It is normal for a TV screen to get hot during prolonged use, but it should not reach excessively high temperatures that are enough to cause a fire or melt the components or chassis of your TV. It’s just like your computer when you use it for prolonged hours. You will notice that a computer gets warm when you touch the body and its sides when you use it for more than 30 minutes. You will see the same results with your smart TV. Treat it well like a computer or any other sensitive electronic device, and it will survive daily use. Will Heat Damage a TV? A little heat will not damage your smart TV. That is what heatsinks are for to help you manage temperatures higher than usual. But there comes the point where temperatures become too harsh for your TV, even with heatsinks, to handle. Your smart TV will be damaged, in that case. Extreme temperatures, whether hot or cold, will cause your TV not to change pixels properly. That is why you need to keep your smart TV within the ideal temperature range for it to work correctly. Why Does My TV Smell like it is Burning? If your TV is working and emits a burning smell, there’s a chance that the dust collected is being burned by the heat emitted by the circuit boards inside. This goes away easily but should this persist, you should seek professional help from your manufacturer or an authorized repairman. If your TV is not functioning when you smell the burning scent, chances are a component in your TV got burned inside. The first thing you should check is the fuse. The fuse protects your TV from sudden electricity surges or fluctuations. It protects all other components from being damaged should there be any unusual electrical activity. If the fuse looks burned, then a replacement fuse is in order. Replacement fuses must match what the manufacturer used. If the fuse is intact, chances are a component overheated, causing it to burn. In this case, you should bring your TV to an authorized service center for repair. Also, look up for any recall orders that involve your smart TV. Have your model and serial number ready, so technical support can easily check any past issues from other users. WARNING Do not attempt to make any repairs to your TV yourself, as you could injure yourself or destroy your device. Can a Smart TV Get Overheating in the Sun? You should not use your smart TV under the direct heat of the sun. For one, sunlight on your smart TV causes a high amount of glare, which makes images hard to see. Second, the sun can exert an excessive amount of heat that can damage your TV. As listed above, excess heat causes pixels not to transition correctly. Lastly, direct light exposure of a smart TV also causes humidity, which can damage the components of your TV. TVs are indoor appliances by design, and you should not expose them to outdoor conditions. What is the Best Smart TV When it Comes to Temperature Management? If you want a smart TV that can withstand harsh temperatures better than others, you should consider LG or Vizio. These two brands have no known history of defective units that overheated on a large-scale. Another good one would be Sony, who has long resolved the overheating issues with their Bravia. You can also try Samsung, who has good after-sales support should there be any unusual activity from your TV. At the end of the day, you may be able to choose a smart TV that tolerates beyond usual temperatures, but if you still do not give it proper care, it will be prone to damage.

2 menit TV tidak bisa nyala tapi lampu power hidup seringkali dialami oleh banyak orang. Kira-kira, apa penyebab dan bagaimana cara mengatasinya? Yuk, simak ulasan lengkapnya lewat artikel berikut. TV merupakan salah satu barang elektronik yang keberadaannya cukup penting di rumah. Bahkan, sebagai salah satu media hiburan, orang-orang rela memilih merek tv tertentu dengan harga mahal agar kualitasnya terjamin. Namun, tidak menutup kemungkinan televisi yang kita miliki rusak seiring pemakaian bertahun-tahun. TV tidak bisa nyala tapi lampu power hidup menjadi salah satu kerusakan yang sering dialami, lo. Hal ini bisa terjadi karena banyak faktor atau penyebab. Apa saja penyebabnya? Penyebab TV Tidak Bisa Nyala tapi Lampu Power Hidup 1. Komponen Elco Bermasalah Komponen elco yang bermasalah bisa jadi penyebab TV tidak bisa nyala tapi lampu power hidup. Kondisi seperti ini dikenal dengan istilah mati standby sehingga menyebabkan televisi tidak menyala, tetapi lampu indikator power masih hidup. 2. Horizontal Flyback Tidak Berfungsi Sirkuit horizontal yang tidak bekerja sebagaimana mestinya menjadi penyebab televisi tidak bisa nyala kendati lampu power hidup. Biasanya, transitor horizontal short tidak menerima sinyal input dari driver sehingga komponen ini tidak aktif. Sementara itu, penyebab driver horizontal tidak bekerja karena tegangan untuk driver tidak ada karena transistor driver yang telah mati. 3. Tegangan Regulator Drop Umumnya, tegangan regulator drop bisa mengakibatkan beberapa masalah pada TV. Selain televisi tidak bisa nyala, penyebab lain yang ditimbulkan yakni TV tidak ada gambarnya. Hal ini bisa jadi karena ada gangguan dari komponen regulator TV. Pasalnya, tegangan regulator drop menyebabkan TV tidak menyala dan biasanya terjadi pada beberapa level tegangan tinggi saja. Cara Mengatasi TV Tidak Nyala Tapi Lampu Power Hidup Pada dasarnya, mengatasi TV mati meskipun lampu power hidup bisa dilakukan dengan beberapa cara. Apa saja? 1. Membuka Rangka TV Cara Pertama Cara pertama yang bisa kamu lakukan adalah membuka rangka TV. Namun, pastikan terlebih dahulu semua kabel tidak terhubung ke arus listrik. Kemudian, lakukanlah pengukuran tegangan pada bagian B+115 televisi tersebut. Umumnya akan ada 2 kondisi yang akan kamu temukan. Pertama, jika pengukuran menunjukkan B+ normal, maka lanjutkan ke pemeriksaan komponen transistor horizontal. Kedua, jika B+ tidak normal alias drop, maka lepaskan atau copot transistor horizontal dan ukur kembali apakah masih drop atau tidak. Apabila tidak drop, maka permasalahan utamanya ada pada transistor. Akan tetapi, jika masih drop maka kemungkinan power supply yang bermasalah. Seandainya kamu merasa kebingungan dan tidak tahu mengenai komponen TV, sebaiknya panggil teknisi. 2. Gunakan Tombol Switch Channel Cara selanjutnya yaitu dengan menggunakan tombol switch channel atau volume. Setelah menekan tombol switch maupun volume tetapi tidak ada perubahan, maka terdapat salah satu komponen dalam TV yang bermasalah atau sudah rusak. Apabila layar TV tidak mengalami perubahan dan tetap mati, penyebab utamanya ada pada komponen elco yang bermasalah. Kondisi ini menyebabkan televisi mati standby, yakni televisi mati tapi lampu power hidup. Kamu bisa mengganti elco baru yang bisa didapat di toko-toko elektronik. Namun, catatan yang mesti kamu perhatikan yakni kesamaan spesifikasi elco. Pilihlah spesifikasi dan karakteristik elco yang sama dengan elco TV sebelumnya. *** Itulah ulasan mengenai TV tidak bisa nyala tapi lampu power hidup, Sahabat 99. Semoga bermanfaat, ya.
