Large dust circle on a Toshiba 50H95 RPTV

After 9 years in ops, I notice a large "dust circle" on the center of the screen when displaying a light color background. It is livable and you will notice it.

Not sure if this dust build up on top of the glass lense. How do I get to clean it ?

I also notice this is a front panel I can open up right under the screen (and between the two speakers). Of course, it has warning about high voltage stuff inside the panel.

No the front panel will only give you access to the CRT circuits. Remove the back panel. UNPLUG your set. You should be able to reach inside (its a stretch for sure) to clean the screen, clean the tubes and if you reach up behind you can actually clean the mirror. This will greatly improve your picture. Do not use windex just a damp soft cloth then dry with a soft cloth. The mirror cleaning is most important to get a nice bright picture. Over the years the mirror tends to get dull. Hope this helps.

We can't seem to get the green out of the television, please help


Sound like a bad degousing circuit. Try using a large magnet. Hold it near screen then do a circle 4 or 5 times last time hold near center of screen and pull away. You can also unplug unit for a couple of hours. Hope this helps.

Red cirle in the center of my screen durning dark scenes


This sounds like the light engine has gone bad or has dust/dirt in the light tunnel or DMD assembly. The light engine would have to be removed to check for dirt. If the engine is bad it can cost over $800 just for the engine not including shop charge. Unit would need to be taken to a repair shop to find out what is actually causing the problem.

Faint red blotches visible on light backgrounds on Sony KDF-42WE6


Convergence issues usually present as colors not lining up or a sort of "3D" effect like when you had to wear the green and red glasses. I'm no expert but it sound like you may have a magnetizing issue. You can test this by placing a large, very strong magnet on the "blotchy" area.

Slowly move the magnet in an ever widening circle. Pull the magnet back off the screen about an inch once you have circled the entire blotch but continue to rotate the magnet. Do this for about 5 minutes. If you don't see any change once you may need a stronger magnet or this is not the problem.

I had the same problem with a 6 year old Toshiba 50H13 and I found this tip online somewhere. I used a half dollar sized, rare earth magnet. I noticed a change almost immediately.

Hope this helps
