I picked up A Vizio VP50 with a bad upper buffer. I had the buffer repaired and got everything back together. The TV now works but the quality of the picture does not seem right. While watching a see a slight "aurora" of greenish purplish colors on the picture. I know these sets are 1080i but I would have expected a lot better picture. Anything to look for or is this typical of this set? I could try to take a picture but I'm not sure it would show up.

Re: Vizio VP50 20a Poor Picture Quality
Ok did some trouble shooting. Fuse on x-Main was blown. I had 209 Vdc on one side of the fuse. But when I replaced the fuse the screen would not come on at all and there was no voltage at either side of the fuse on the x-main. -

The X-main is shorted then. You can repair or replace the board.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Hello, Last week I bought the 50" Sony X80j tv everything was working fine, untill I plugged the tv in a ups power supply 650va the tv remote control became unresponsive and the TV became laggy after a while the picture quality isn't the same as before the tv seems less brighter and the picture is somehow blurry, people's faces don't look as natural as before, there is a mini orange-pink tint to the edge of people's faces especially in NETFLIX Dolby Vision like in One Piece ep1 Alvida skin tone, my intention was to protect the tv but something went wrong I checked the ups with a multimeter,... -

Hello!
I recently got an old VHS player from Panasonic and just for fun I want to try to repair this device. It is an AG-1000B portable VHS player from 1990 and it has a problem with picture quality in playback mode.
Picture in playback mode is very noisy and often loses sync but the still images are nearly perfect.
I want to know, is this something that could be solved by recapping or is the video head likely gone?
Also, what mechanism is this?
Any feedback is appreciated!...05-06-2024, 07:16 AM -
Hi I inherited a Vizio M65-E0 that isn't working. It must have been dropped on the corner because I found that the infrared circuit had a capacitor with one end broken off of the board and some green corrosion around the plug to the main board. I re-soldered the capacitor and cleaned the corrosion well and tried turning the M65-E0 on and I was successful. My problem is that while the back lights come on and appear to perform local dimming there is no picture or sound. It kind of looks like you are looking at the TV through a very dense fog, where changing the input on the remote will change bright...
