This might require attention by a qualified service technician.

42" Plasma, no picture, sound


Hi:
The best possible solution to your problem is to replace both sustain boards at the same time, The X and Y sustain boards. LG tech support recommends replacing the digital board as well when replacing their boards, even during LG's tech training seminars they suggest you replace all major boards for continued viewing enjoyment. But in my experience you should replace the X systain also, but make sure the Y you replaced is still good.

Sound working no picture


Depending on the events leading up to what happend...
Was your plasma tv recently transported or moved from one area to another?

One thing about plasma tv's if you lay them horizontally or has been tilt at a certain angle they will have problems projecting any picture. PLASMA tv's should ALWAYS stay vertically standing. you can let it stand where it should be for atleast 24 hours ( i recommend upto 48 hours) without plugging it in.. (no electricity what so ever) then check if it works.

About the click you heard, it might have been a blown fuse. Probably resulting from plugging in the tv while it was in a "chemical inbalance". therefore my above recommendation is a bit too late. if you still have warranty then you have no problem. just the hassle.

42 inch LG Plasma TV - Lost picture


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.

It definitely has a problem, possibly the Y sustain board and y drivers Up/Lwr. Best suggestion is to take it in for service or have someone come out how has experience with Plasma repair.
