Bad or leaking caps per an LG bulletin was issued for this model and all three series units of tis model. You'll need some test equipment, mainly a cap analyser 88, solder station and some expereince in SMD components to fix this unit. But it can be fixed, not an expensive fix, and if you're not too sure how to do it take it to a qualified tech... Let em know there is a bulletin on this unit...
Good Luck!

LG 32LH30 LCD TV Problem


IMO Seriously for $119 it's not worth it.
However, it does sound like a capacitor problem
If you are "Serious" about fixing I'd find a TV repair Forum.
Else I'd go here and get a new one.

Mitsubishi vs 5043


I turned the set on and everything was fine, then the screen went black and mullti-colored horizontal (arched) lines were flashing across the screen. The next day I turned the set on and everything was fine for about 5 minutes then the problem reoccures again. Haven't looked for solutions till now.

Screen tuns black after 15 seconds and comes back after about 15 minuts


The solder joints on the vertical output IC have cracked. This is a very common problem on those sets.
