Vizio VP50 HDTV10A (Yellow he issue.and Green status light flashing)

[tschneeee]

When I plug my tv in, the green and amber light start flashing about 20 times (10 times for each yellow and green) and then the light goes to a solid yellow. I'm replacing bulged capacitors so hopefully that issue. Does anyone have anything additional they could tell me?

Yes replace all the caps under 100v. I think there are 25 total, not counting the large ones. Had to do this on my 2007 Vizio P50.

Thanks bud. Nothing else seems out of the ordinary
from my perspective so I think it is the caps.

I use a Cap Wizzard but there are cheaper ones that work well like the Anatek Blue ESR meter. 99 assembled or 80 in kit form. Unsoldering and replacing all of them is time consuming and expensive. In the the long run a ESR meter will save you money if you do repairs regular basis

Update: replaced all caps. the tv turns on perfectly.HOWEVER, all the screen shows is red right now. Does this mean bad buffer board? Not too good at this.

Check and/or reseat all power and LVDS cables first. You may have accidentally disturbed another cable.

Also how many LEDS on logic board are lit when set is on, and how many are blinking?

After replacing the caps on power supply, the tv stays at a amber stand by after going from green to amber for a total of 20 times. However, there's something else wrong with it.

Is it worth mentioning that I replaced all capacitors and after that, about 2 minutes after plugging in the tv, one of the capacitors started smoking and i smelled burned residue. I don't think I used quite good solder. Could I have messed the whole power board up? Also on the logic board, I see two lights in the center out of the 4 that are lit up. Here's a picture.

3 lights now.

Smoking caps is NEVER a good sign. Check the one that smoked for correct polarity. It is possible it got reversed. If not then there might be a problem on the circuit that cap is protecting.

3 leds lit on logic when on with picture is D3, D4, D5.

EDIT..... Need pics of area where cap smoked.

Thanks Magic I REALLY appreciate your help. Turned the power supply over and saw corrosion on the solder ends of the capacitors. Is there a way you can tell me how to test circuits on the power supply?


What does the logic board lights say? I've been trying to find a service manual. Before I buy a new power supply I really want to know that it is defective before.

Thanks again,
