    Thats a DPTV 335 chassis the tube shouldnt be bad on that model. It may just need the blue and green CRT coolant changed which is causing the red tio be dominate. If you go to this link you can get the service manual emailed to you and they will provide free tech support to talk you through the coolant change. heres the link.

I have some picture distortion - pink fuzzy color where white should be (like on hockey ice). I'm trying to determine if the t-con board is to blame and if I might fix it easily


Hi Bill.

I don't see a specific model for your TV, but have owned a rear projector system before. There is usually a sub-menu where you can do fine alignment of the Red, Green, and Blue projectors to get rid of the pink fringe. There is generally a white crosshair at center screen where you can fine align the three colors to get rid of the fringing, and sometimes an advanced menu where there are crosses all over the screen that you can individually select and fine tune, (tweaking the different optical distortions of the individual projectors to overlap).

If the fringe is a big swath instead of a fine edge, or if a color is totally gone, then you may be talking power amp issues. For fine fringes, the adjustments usually work fine.

Hoping that helps!

My monitor screen is red what normally is white. Why?


Check all cables and replace all cables to rule them out. Is this a TV or a PC Monitor? If it's a TV them try going into the menu and reset all settings. If its a PC change cables (VGA or DVI). If RED is still present then it's gone bad. Hope this helps

The color on a Magnovox TV rear projection went to black and white. How do I fix it?


You don't, probably. Sorry, but this is a truth. These large projo's have become nearly extinct, and if you call a service man he might hang up on you. I won't work on them any more because parts are nearly unvailable as are solutions from the factory. It's old enough you'll do yourself a favor is you rid yourself of it and buy a newer flat screen TV.

6d3e6c1f-c991-4dcf-aa4f-930b9d111d87.pngBelow are two of the most common problems encountered with projection TV sets.

Problem #1 - CONVERGENCE PROBLEM

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on Projection TV sets and a fairly simple DIY fix.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on - TV may also make a chirping noise.
Here are some photos of convergence problems.

b801654a-71fa-4c28-b84f-3a1a6801d5e3.jpg
Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

CONVERGENCE SOLUTION
You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.

This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from TvRepairKits.com

Their kits include a step by step instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Problem #2 CRT Fluid is Cloudy

Projection tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around video.


What you will need to do is replace the coolant and clean the crt. You can get a repair kit from TvRepairKits.com . It includes replacement coolant,step by step instructions, support, etc.
