Hi all, got a new set to look at. This one is a Vizio D60-F3 it has no standby light, wont power on and has no pi or sound. I have checked continuity in the fuse. I checked the pinouts to the motherboard several times and I am getting no voltage on any of the pins. Guy who gave it to me told me it was turning on then going off and then it stopped coming on. There are pics of the model and powerboard. Thanks
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Can we see the pictures of the whole backside of the TV showing all the boards so we can see how all the boards are connected together?Never stop learning

Are you getting about 160VDC when measure right between the two legs of main filter cap C2 (no need to turn the TV ON)?Never stop learning

Re: VIZIO D60-F3 Wont Power ON, No Standby, No Picture, No Sound
The first thing I would do is remove the power supply from the tv and inspect or resolder the connections on the transformers, they like to develop poor connections and go intermittent.
Also check the solder connections on any of the components mounted to the heat sinks .Last edited by R_J; 10-29-2020, 05:39 PM.

Show us good clear straight shots pictures of the whole bottom side of the power supply board.Never stop learning

Re: VIZIO D60-F3 Wont Power ON, No Standby, No Picture, No Sound
You probably already did, maybe check those 2 diodes D102, D106, D103, maybe heat up your electrolytic caps with a hairdryer and see if it wants to start up if it does, you probably have a bad cap or 2 or more, test power cord for continuity. Seems like the caps should be ok tho, they've only been out for 2 years.Last edited by nomoresonys; 10-30-2020, 04:36 AM.

Re: VIZIO D60-F3 Wont Power ON, No Standby, No Picture, No Sound
You have 170vdc across the main cap, now with negative meter probe on cap negative (M10), Check for voltage on R12, on the end sticking out from under the heatsink. If you have 170vdc on R12, (leave negative probe on M10) check the voltage on D106 cathode (white mark on diode)
Also check the voltage on D3 cathodeLast edited by R_J; 10-31-2020, 09:44 AM.

Are you getting any voltage on the +16VS on plug CN201? What about the voltage on D3?
Can you read the number on U1?
The voltage on D106 is jumping around because the ic is likely operating in burst mode.Last edited by R_J; 10-31-2020, 02:32 PM.

D3 is 14v
I dont see a U1. is it one of the 3 U2, U102, and U402?Last edited by rebelkustoms; 10-31-2020, 02:44 PM.
