Re: Toshiba 50L1350U - Dual Image/Horizontal Shift After Power Outage

After I tried the heat gun trick, I gave up and walked away an left the TV on. I came back to find the TV was no longer displaying anything at all and no backlight. So as it stands, it just doesn't do anything at all.

considering replacing the mainboard.

I took a heatgun to the edges and sides and everything, I didn't notice any difference. I didn't get it TOO hot, but it was a legit heat gun and warmed it up pretty good. What else do you suggest I do?


Sorry this took so long, but I'd be happy to help. You just want the voltage between the on/off LED? I'm not sure what a "driving led" is....

The "dual image" kind goes from a normal image back to dual every second or so (sometimes less, sometimes more).

It's like it wants to go "into focus" but just can't.

the light doesn't flicker, no. the backlight stays on entirely....

This happened right after a day of power outages, so I presume there was a surge. It worked fine for the duration of most of a movie after the outages, and then started doing this. Everything seems to work just fine except for the "shiftiness" which you can see in the pictures. This happens to the OSD stuff as well as the movies. Happens with HDMI as well as analog RCA input. Nothing else seems to be amiss.

I already opened the back to check for any fuses or burnt...
