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

On a Panasonic TV the 10-blink error code can sometimes be caused by low voltage running through an HDMI cable, particularly from a Media PC or some video game consoles. Try disconnecting any HDMI cables and unplugging the Television for 30 seconds, then power it on without the cables attached.

If this works, connect the cables to the front panel (usually HDMI-3) which uses a different controller board.

Definitely sounds like a power supply problem. Check with your local TV repair/service center about getting it repaired or replaced.
