I had this problem before on my LG TV. My solution is to put a 12V fan on the tuner board processor. The problem is caused by the TV overheating and when the tuner CPU overheats it sends a high temperature OFF command that instructs the power board to shut the tuner board off (although the rest of the TV stays on). This is why it sounds like a click when it happens. You cannot likely get a TV repair man to fix this because the LG TV's do not have adequate heat control other than vent holes on the bottom and top. This is a design flaw that started a class-action lawsuit against LG.

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.

The picture went blank on my 42 inch Olevia lcd tv


What happened and can it be repaired for less than the cost of a new tv?
Anyone would be hard-pressed to give you a definitive answer to that question but if, as it very well could be, the main power supply has failed, you may be able to buy and replace this yourself and I would guesstimate the cost at under $150 US for a new board.
Disturbing part is the chance that the supply was damaged by another problem downstream from it. Most modern supplies can protect themselves from and overload so I think the supply was at fault rather than being a victim.

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
