I just fixed this problem myself on my TV by buying a power board from discount-merchant.com
It was $136 including 3 day Fedex.
It really was easy. Unplug from power. Remove 4 big screws, about 10 smaller screws, then 6 screws on the power board once you take the back off. There are about 6 clips on the board to undo too. Take a picture when you open the back for good measure.
It took me less than 1hr.
No affiliation with the website. I instant messaged with a tech 1st, they reinforced the research I had already done.
Should have been 3300 UF 10V caps that were bad? Shouls have been replaced with 3300UF 18V. 50V is huge. If it was replaced with a 50 the polarity may be wrong or the cap it too big to be seated property. Sometimes the caps just dry out and even a normal looking one will be the culprit of no OSD. Are you getting an LED fault code blinking? That should be a red led. Do you hear the relay clicking.? When you replaced the caps did you charge them? Just plugging in the set without trying to power it on for about 20-30 mins. I may be able to help you
