Vizio M60-C3 left side of screen + a couple other areas dim

[frannyjunk]

My Vizio M60-C3 was dead. No power, no lights. Just nothing. So I took the back cover off and noticed 4 bulging caps on the power supply board, so I replaced them (green low esr capacitors in the picture). The tv now works! But there are some areas that look dim (see picture). In particular, the left side has a dim band. I know that the led strips run horizontal, yet this band is vertical. Could it be that the led driver board is bad? Could the blown caps have taken out the led driver board? Or is this just a coincidence that every left side led on each strip just went out?

open the panel and check your back-lights, repair or replace

I will do that if I have to. The thing is that the pattern of the dark areas seems suspicious. Normally, if a string of LED backlights go out, there is a horizontal dim area. In my case, the dim areas are vertical. Sould I attempt to replace the LED driver board first?

Strips could be arranged vertically or horizontally.

I have the same exact issue with a fixed M60-C3 ( 4 bad PSU caps ).
I see almost the same as the picture in initial post.
Was there ever a solution to this issue ?

I just repaired a 65" Vizio. The lower left quadrant was dim. When I got it apart there were 16 strips, and only 3 were working.

Yep, same here, opened it up after I repaired the PSU and a few strips were out, some where half out.
I ordered a full set from ebay and will report back the repair.

Could the cap issue have caused damage to the strips maybe through overvoltage ?

Ok, so I got new strips and now the TV is fully working.. It seems this issue maybe spikes the LED strip voltage ( guessing ). I am also attaching pictures of what the caps look like when in need to be replaced.
