Re: Vizio P-Series 4K tv with temporary sound and no picture P652ui-B2




In your experience with this line, are one of the symptoms a fading power indicator upon startup? Comes on with power up, but then fades after about 8 secs?
I have a p502ui-b1e that I have changed every board, but to no avail...same symptoms as orginal post. No video, had sound. Changed, tcon, main, psu and led driver...thinking I may have purchased a bad main now?
Any insight?
TIA...

Re: Vizio P502UI-B1E has no backlight, no voltage from driver board to LED's

I am having same problem. I have changed all boards except for TCON board (its on order). Anything else I can try in the meantime?
New:
PSupply
Led driver board
Main board
Changed U202 on original Main board (Nothing so, I changed the board)
