Lg plasma 42PC3D no picture with sound

While the TV was on, I heard a clicking sound and the picture went out but sound was still there. I found blown fuse on ZSUS terminal board and replaced it. It didn't fix the problem and TV is now turning off by itself right after pressing the on button.

I know you already replaced the board, this is for future searchers. If you heard a popping sound, then the picture went out, there is a 32 pin Sanyo module that goes bad on the board. That's probably what caused the fuse to blow. Replace the module, then replace the fuse. The module is less than half the cost of a used board. Since this was a popular model TV, there are lots of replacement boards on the used market.

Check for blown fuses on the rest of the boards as well, if there's a blown fuse on any of the bds the power supply will turn itself off if it doesn't sense a load. hope this helps.

From your description it sounds like your TV it's actually on you just can't see a picture. That is usually caused by your Zustain boards. The zustain boards are located on the left and teh right side of the TV. You can check the fuses to see if one of them is blown or you can leave it on and see if one of them does not heat up. You would have to replace the board. You can find part at www.interliquidparts.com

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.
