Hi,
I've got a Vizio vo47lfhdtv10a tv that, when I got it, wouldn't power up. I opened it up and found a bad capacitor on the power supply board and 4 bad caps on the inverter boards. I replaced all of them with low esr caps. One of the pictures shows where the bad cap was on the power supply board, the board was pretty charred, and I re-flowed all of the solder connections in that area.
After doing that, the TV now powers up, but I do not get a picture. The Orange led turns to White on the front.
I checked the voltages on the power supply board and they look good. I also checked to make sure that the fuses were good on the inverter boards, they are.
Along with the "no picture" issue, the power on/off button works very inadvertently, sometimes working, and other times not.
Is there a way to test the inverter boards?
Please let me know if there are specific voltages you would like me to check. Like I said above, I did check them, and but there may be some voltages that I should check that I was unaware of. Or you may want me to recheck ones, which is fine.
Thanks!
