LG 50PC3D won't turn on

[d0rkster]

Tv is around 8 years old.
I have had ongoing problems with this tv for a while now. Whenever I turned on the tv, the screen would flash and would turn off right afterwards. I had to turn it on multiple times before the screen stabilized to allow me to continue watching it. Perhaps, it had to warm up first?

Recently, my tv is unable to turn on at all and has completely died on me. There is no led light or anything that flashes (normally should be red).

I opened up the tv and the capacitors have gone bad. I am about to order the capacitors on ebay but I was wondering if there's any other parts that would be preventing my tv from turning on. I don't want to waste money on capacitors and then find out it still doesn't work. Would buying new capacitors solve the issues I am currently facing? Thank you.

I'm new to FPD TV repair myself. I would order and replace in a heartbeat. It worked the first time in my case. The only precaution I advise is use a decent 40W soldering iron, care, and good technique to avoid damage to the board. Either order a preselected cap repair kit or search the forum for selection guidelines. My LG50PC turned out to have another issue as well, so I had to send off the Y-Sustain board for warranty repair.

DO NOT waste your time on ebay for capacitors. Some sellers have genuine products some have fakes.

Buy from Digikey or Mouser and get good quality capacitors.

And yes most of the time replacing the caps will fix the problem, but not always. Failing caps can cause damage to other parts in the circuit sometimes.

I will say that I repaired a PSU with the same symptoms out of a Vizio P50hdtv10a just by replacing the caps on PSU. Yours appears to be the same PSU as in mine. It has LG components in a Vizio case.
