Question about Mitsubishi WT-46807 46" Rear Projection Television

2 Answers

RGB on each side have a hard time lining up. After some time the screen will get fuzzy and then the RGB will line up. It seems to take longer and longer for this line up. Is this worth fixing or should I consider buying a new TV.

Mitsubishi WT-46807?

If convergence goes in and out you need to replace the two STK-392-570 convergence chips this set uses.

I have repaired a lot of these sets and sometimes the chips are flaky---convergence will come and go--in every case replacing them cured the problem.

Considering you can buy a pair of the chips on Ebay for about 12 dollars plus shipping if you or someone you know can do this repair--you can save the set and a lot of money.

Most shops are going to get at least 300 for this repair.

By the way-----I HAVE START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR.

They tell you everything that you will need to do it and how to do it. The reason I have them is so many people here have asked me the same questions I composed them---I got 2 comments today from people who had success with the instructions.

You have bad solder connections on the convergence board. when they heat up, the metal expands and completes the connection. when you turn off tv, metal constricts cooling down. just simple easy soldering. no parts need replaceing. very much worth saving the tv.

Nothing showing up on tv screen, only fuzzy lines


hi,
exactly the same problem here. I could suppose its a firmware problem because it happen with or without the hard disk. I also checked "stand alone" the hard disk and it works properly.
I'm trying to find if its possible to start an automatic firmware reloading from an external USB pen connected to box.

What is up with my 360 when ever i play it for about 30min it shows green fuzzy lines down the screen of my tv and purple fuzzy lines down my tv screen and after those two happen sometimes it will have red...


well definitely video issues of some sort. if you have a second video cable (or hdmi cable if your unit supports that) give that a try.
*assuming that doesn't work Unfortunately it sounds more likely that it's an issue with the video card inside the xbox. this may be repairable by a professional.
if you have it under warranty i would contact microsoft for a replacement/repair https://myservice.xbox.com/en-US/Pages/Welcome.aspx or call Toll free: (800) 4MY-XBOX

Xbox 360 Blurry/Fuzzy Screen


The machine is overheating and the graphics chip on the main board is acting up cause of it. Make sure there is no dust or dirt blocking the air vents that would cause the system to heat up more then normal.

If that doesn't do it then maybe think about getting a cooler for the system, here is a website that talks about a few of them. Click here.

If that doesn't help then your mainboard is going bad and would need to be replaced.
