Check the CRT base card to green CRT for any loose solder terminals. Re-solder all the suspected solder terminals by applying a little more solder to each terminals. Check the solder terminals of the CRT base connection socket too. The fault is with some loose solder terminal itself at the green video output stage circuit. Gopakumar Gopalan Google

Sounds like the red picture tube could be shorting internally which would cause the "all red" condition. In which case you'd have to replace the red tube. Are there horizontal (slightly slanted) lines through the picture as well when this is happening and a very very bright screen? If so it's most likely the tube.

SOURCE: Picture Problem

In that set its usually a bad picture tube. The lines you are seeing are called retrace lines. You can take it to a shop and they may be able to rejuvenate the tube

SOURCE: Samsung CRT HDTV - Color Problem - Red, Blue, No Green

This will be a lack of green drive caused either by the green output transistor having failed or no green output from the driver IC. As to which you have depends on how old the TV is. These are located on the CRT base (square type board connected to the neck of the CRT. You would need a multimeter to check the voltages going to the green output on the crt. It is also very possible the CRT is internally faulty giving no green, if this is so, you will need the crt (tube) to be replaced,it is not very economical to do this now a days.

Mitsubishi ws65819 rear projection tv looses green color after 2-3 minutes


Check all the voltages at the other pins to its crt base socket. Check the video output transistor's solder terminal. Check the voltage that comes to green drive transistors' base. Refer its circuit diagram for more details. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy Pull up older posts.

Picture stays on for a few minutes then turns off.. what could be the problem? light bulb? can i do it myself?


This model TV is a CRT projection and does not have a lamp. It has 3 CRT tubes (Red, Green and Blue). Unfortunately, you may need to have a trained TV technician diagnose this further.

I have a Sony 47 inch rear projection tv that is about nine years old When the set is turned on it has a good color picture but after a few minutes it tuns to a complete green sceen. Can you tell me what...


The green CRT may be intermittently bad or the focus screen block. Certain sony's are common to have bad CRT's. When the screen goes green does the set shut off?

Green horizontal lines on screen no picture


The green CRT's (color picutre tube or color wheel, or ballast) will need to be tested for replacement.
It is quite common with these tv's

You will need an ohmmeter and or voltmeter and test each component for currency and accuracy

TV screen goes blank but power stays on


Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.

Problem with color


Yes you have a problem in the red crt driver board. Most likely the driver transistor is failing. This is a component level repair, so if you have no experience with TV repair, play it safe and call in a trained tech to assist you in this matter. Good Luck

Screen turning pink


If the pink overlay goes away gradually, you could have weak picture tubes (CRT's) If the color jumps in after warming up, it could be a bad solder connection. If you haven't had a good picture to watch for a long time, I would be tempted to put the money towards a new HDTV set as those older Mitsubishi Rear Projection TV's had a Lot of bad solder connections in the past, and by fixing one problem another could crop up in the near future.
