I have the same problem. No picture but have sound. Have checked capacitors, fuses and looked for any obvious sign of damage to components but nothing. How would I go about diagnosing what board or component on the board is the problem?I have the same problem. No picture but have sound.

Re: heard loud pop now have no picture i have sound .
Hello Jay, The pop sound you herd was a blown capacitor, Open the back cover and check the main capacitor in power supply, It need replacement. But first check if the oil of the capacitor drop on the circuit then it must first cleaned then dry the area where the oil of capacitor spread. Thanks.

This may be due to a faulty power supply. This is best repaired by an experienced electronics technician. These TVs often have capacitors in the power supply which become faulty over a period of time and need replacing.
Hello Tiangston9.
These plasma TVs have a common failure with the Ysus boards, more specific an IC that is underneath the big heatsink. The capacitors in the power supply became defective as well.
Check the link to find parts to fix your TV.
Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.
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
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.
