This problem is always either the ysus bd or zsus bd failing and sometimes both. As a rule because these boards work together as the scan and return when on fails I replace both. The part # for most versions are YSUS = 6871QYH039C and ZSUS = 6871QZH044B and can be found on either the Andrews Electronic or Vance Baldwin website.

LG plasma tv made loud popping noise


The plasma gas tubes may be damaged or the gas couldve leak out. remember plasma have to remain upright at all times even when transporting them, if they are not you should just set it up straight for about 3-4 hours before turning it on.

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.

42 inch LG Plasma TV - Lost picture


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

It sounds like you are getting interference. It could be coming from another unit you are using (in other words the tv is receiving signal from both the dvd and the cable box at the same time). It could also be a problem with the wiring. A simple electrical burst or move of the tv could have actually disabled both connections. Let's hope it is that because the solutions get more expensive from there.
