Question about LG RZ32LZ50 32 in. LCD Television
After my LCD TV has been on for about 20 minutes, the picture goes black, but the sounds still plays. It's weird.
Any ideas how to get this fixed??
After extensive testing of my LG set and finding 6 sets with the same fault.... it was the capacitors on power boards bulging.... It looks like the capacitors LG used were a bit.... well....naff... I replaced them with new ones from an online supplier and the set has been ok for 8 months now.... LG engineer told all my customers that the screens had gone... Fault starts as sound and no picture, turn off and on a few times and the picture returns..... seems to be on various models...... Hope this helps.....

The inverter is the most likely caulsa as it supply the back light with power

Same problem with LG 42LG30 lcd tv. From what i have read up on, it seems to be an issue with a part known as the inverter board
