Our LG 50" plasma tv screen went black after a popping noise but still had sound, after great diliberations decided to take the back off and have a peek!
We unplugged the tv and tested the fuses (there were three we could see) one had blown, the one on the left as you look at the back of the tv it also has one above it. We wrote the code/seriel number down and took the fuse to the electrical wholesalers Maplin and bought a pack of 10 fuses for £1.29 replaced the fuse in the tv and everything now fine!!!!!!
Hope this might be of use to anyone whose lost the picture after a loud popping/snacking noise but still has sound.

Hi , I recently had the same problem which I was determined to fix . So I did a few weeks of research to find that it was the Y SUS board which burns out. I'm sure you realized that the TV gets hot. Personally I think this is why. circuit boards don't like heat and I've learned that the cooling fans are a joke. I replaced the board and got my picture back. I proved the fan theory because after the screen started to act up. I placed a cooling fan near the vent holes on top and the problem cleared right up,It also helps if you lower the brightness which helps out on the heat situation.I will soon be adding a fan with a temp. sensor. This shoud help if your screen has lines when you initially turn the cool TV on.then I have Some other costless solutions. Hope this helped these are great TV's and like our cars we maintain them not throw them away..................................Mr Wiseman

This is almost certainly the device that sends electricity to the the plasma in the panel after failing. Bring to your local repair shop and expect to pay 300-400 parts and 100-200 labour.

Cheers,

I need remote code for sinotec 42 inch full hd tv


If you have a new universal remote, you can use its code search feature to find a code for your Sinotec TV. If you search through all codes stored in the remote with no result, you may have to try another universal remote. All programmable remotes do not store all possible codes in their library.

My Sinotec 42 inch TV Model MP 421 MANUFACTURED jULY 2007 takes up to 15 minutes for the picture and the sound to come on after switching on with the remote control small blue light on what is the problem?


The start voltage to its SMPS [power supply regulator] section has the fault. Contact any service technician. One or more resistors on the start stage should be checked for value deteriorated.

Olevia 42 inch Flat Panel has power supply issue... Blue light does not come on and tv does not turn on... I have tried all different things to get tv to work with no positive results


What did you try so far? The main power supply MUST have at least the 5V standby supply section working. This 5v is used by the main control board to send out the command to turn on the main power supply section which will power up the rest of the TV circuits when the power switch is activated either by the power button of remote or on the TV powern button. Look for this 5v first.

If you have the original remote (RC-A07) for Sinotec tv, then press and hold down the music button for about 10 seconds. This worked for me.
