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

Tv powers up but goes directly into stand by mode


An Electronic component has failed. Unless you can repair circuits, take it to a shop or friend who can. Consider cost of replacement. A few hundred will fix an old tv, a couple more and you have a whole new unit.

Power will not stay on


With a problem like this, I would use the warranty for the TV.
It's possible a circuit board failure has occurred and the TV is automatically turning itself off to protect it from further damage. Is normally called " Protection Mode " for most TVs.

Being that it's 2 months old, it should be under warranty regardless. I would recommend contacting the store of where it was purchased and have them help you with the warranty issue.

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.
