20 Most Recent Mitsubishi VS-50705 50" Rear Projection Television Questions & Answers


Picture is not bright

Below are two of the most common problems encountered with projection TV sets. Problem #1 - CONVERGENCE PROBLEMProjection 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.1d5e2cf.jpgff5b9f6.jpg7deade1.jpgHere 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 solution47a7bc4.pngCONVERGENCE SOLUTIONYou 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.comTheir 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 CloudyProjection 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. Pic of a set that needs the fluid changed. Notice how dull the colors are and how white the screen looks. The screen may also look red, orange, dull, etc. BEFORE7c190d8.jpgSet after fluid change. Notice how bright the colors are now. Everthing looks crisp and sharp again. AFTERa798d23.jpg724bcba.pngSolution #2 - CRT FLUID FIXWhat 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.

I can turn the TV

Hi Ron,
To determine where the fault came from, you may activate the "self diagnostic" mode of the unit. Once the unit is in self diagnostic, the led light will flash indicating the error code(first digit) then pause and will flash again(second digit error code). Count how many blinks does the unit have for first digit and second digit. Flashing of the led light error code will repeat 5 times.
Here's how to activate the "self diagnostic mode".
Press and hold the front panel buttons (not in the remote) "Input" and "Menu" at the same time for 5 second.
Let me know how many blinks it has to pinpoint what is the caused of the symptoms.

Cannot adjust convergence

Projection TV sets have two very common problems listed below.

Problem #1) Convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture
