Question about LG 42LB1DRA 42 in. LCD Television

1 Answer

Sound but no picture

I had this same problem and it turns out it was the capacitors. I followed the guy belows instruction even though I have never worked on eletronics before. It was easy and only took about 1.5hrs of actuall work. It took longer to find the parts than to replace the capacitors. I sugest that if you have this problem use the directions. Besides it will cost you $600-800 dollars to have some one come out and fix it for you. You can just get as brand new tv for that.

My tv did not turn on and the sound and picture did not come up.


Good day!!!


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

Tv doesn't turn on ....i know its a power supply problem but im looking for the board of the power supply of a Sony Bravia LCD 32" KDL-32L5000


Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.
  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.

My tv made a loud noise like a vacuum them a high pitch noise and now it wont turn on unless I keep flicking the surge protector on and off.It wont even work when plugged directly into the outlet.


Power supply...The vacuum sound you heard was a capacitor failing. A capacitor stores energy for later use. For example, you turn on your TV, seconds later you hear a "Woosh" and the picture comes up. This is your tv's capacitor discharging. It's a simple fix if you know electronics though I wouldnt recommend repairing this yourself. There are several capacitors inside your TV. Though not fatal, they can give you a jolt. Call a repair man. I hope this helps : )
