Re: Vizio power supply
Can you take pictures of all the boards you have or want to examine?
I just acquired a P42HDTV10A two hours ago. The image was bad but sustainable - it look rather washed out.
I'd love to know the brand and specs of the two capacitors that went bad.
Thanks for reading -
Re: Vizio power supply
The black screen no sound is a common problem with the Vizio 42" plasmas. It is most likely the IPM on the Y-sus. The fuse will not look burnt so if you did not measure it with a DMM then how do you know if it is bad? As for the Vizio with the the bad picture the problem sounds like a bad waveform coming off of the Y-sus. It can be adjusted but you will need the LG training manual and an oscilloscope.Comment
