Why has my LG tv suddenly gone dark


Back-light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

Check resistors in the small PCB connected to picture tube. Check picture tube grid voltages. Check brightness control swing on the IC out put. Note down the IC no and search in the Google for pin configuration.

42 inch LG Plasma TV - Lost picture


This is almost certainly the device that sends electricity to the the plasma in the panel after failing. Bring to your local repair shop and expect to pay 300-400 parts and 100-200 labour.

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.

Dark picture on lg dlp tv


Did you use a generic replacement? Many TVs have a dark picture after replacing the original lamp with a generic. The other issue I've encountered are TVs that have been exposed to cigarette smoke will develop a dark, discolored picture over a relatively short time.
