point out a couple parts...
This is the 2nd TV im working on and want to get it tested and parts ordered. Ive read on here if your blowing a fuse on start up its usually a mosfet, bridge rectifier or main primary cap.
Could one of you guys point out the Mosfet and bridge rectifier for me? I had circled what I thought was them, but it didnt save for some reason...
Samsung HPT 5064

Re: 50" Vizio blank screen
Alright your suggestion to search this forum helped out lots. I thought I already did but apparently not.
So I might have narrowed it down to my upper buffer board, but I dont know how to rule out the Y-board. This is what im getting now. When I remove the upper buffer board the bottom half of the screen lights up. But I still cant seem to get an image on it.
Any other suggestions?
And on my buffer board it looks like some solder got hot and shorted out a couple of the buffers scans. One even has pin...Leave a comment:

Generic question
How long will the capacitors in Plasma TVs hold a charge?
How long will they be dangerous for?
Ive read everywhere from 5 minutes to 24 hours.
Ive never mess with buffer boards before so I just want to be sure.
Thanks Dustin -

Thank you sir. Ill do a better search.
Im just slowly learning from this site and others, I use any tips from members and try to educate myself from there.

Re: 50" Vizio blank screen
The first time I tested the X and Y boards I just had the TV plugged in, this time I actually turned the TV power on and both read at 4.0 volts. The X board reads...VCC 5 and I cant find a number on the Y board.Leave a comment:

50" Vizio blank screen
Well im a total noob at TV repair, but after fixing one I thought it wasnt too difficult so I tried another...
I bought this TV not working so...vp50 HDTV20A
First I took off the back panel and saw a bulged capacitor on the power board and also one on the X-main board. So I replaced them hoping that was all, WRONG. It changed nothing that I can see.
So when plugged in the orange standby light is working then when I turn on the power the green light on the front turns on like normal. In the back their is a green flashing light, im not sure...
