You have to get the 'tubes' replaced with new ones, can be done at service.
the tubes of colors green and blue are getting old, so they cant withhold that much energy while being this old

SOURCE: jvc 24" widescreen tv problem turning on

The tube is not blown or the Tv would not turn on at all. I would say its probably a bad cable or the board that the cables connect to the back of the Tv with is either loose or bad. Try replacing the cables first, then try holding the cables very snuggly in place and seeing if that gives a solid signal for more than 15 seconds. If that doesn't do it, you probably have a bad input card. You would need to have the TV serviced or get a new TV

My Samsung DLP is having the same problem.  Not sure what to do, but I will contact my warranty place for the second time.  Hopefully they'll fix it.  Any other suggestions?

The screen turns blue after about 2 minutes of turning on the TV


Sony TVs has an Optical Block issue. If there is an issue with the optical block, then there will be green, blue patches or tint on the TV display. Try resetting the TV to the factory settings and try Power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue still persists, then TV may require service. You can contact the Customer relations team and check for the available options. Sony had repaired free of cost for such issues. Hence, contact the customer relations.

Tv comes on for 10 seconds then fades to a green tint then turns completely green for a few seconds than turns off


Hi,
Symptom shows tv got problem with green picture tube that need to be replaced.
Rear projection tv has 3 picture tubes, red-green-blue to make color picture.
Since its an old model so spare parts would hardly be available and local tv repair shop will help you to arrange required part, if they can.
Thanks.

The screen is showing green all over the images on the tV


This may be caused when your picture tube is magnetized and it should be demagnetized to return back to normal.
As a simple measure, switch off the television and UNPLUG IT FOR TWO TO THREE HOURS AT LEAST. The longer the better. Then switch it back on and see if it get demagnetized all by itself. This is just a try.
If it fails, try replacing your picture tube. Try to have undamaged picture tubes of old color televisions as they are of better quality than modern ones.

Picture turns green!


The CRT (picture tube) is failing. This is classic in these TV sets, and including many models of the Sony.

There is a short occuring in the electron gun. The CRT would not be feasible to replace even if it was available!

This may be a bad crt or picture tube. Take a good look at the picture when it's on and see if it has a pinkish or greenish tint. This is easiest to see if you turn the color adjustment all the way down. If it looks like the tint is green or pink and the focus isn't great then it's probably a bad crt. Not worth repairing if its the tube.

Video turn pale green/yellow then comes back?


sounds like your picture tube is going out, if its an old tv it would be best to let it die since its very costly to fix these problems. If its new you better get it looked at. It is a hardware problem, nothing you can do about it.

Pink screen


Is your grey scale or Black and white programming pink?? Thats an indication that the green and blue grids on the picture tube are week or that the red is over driving. First thing is take off the back of the set. Find the end of the picture tube and look at the printed curcuit board there. see if you can find and red drive controls there. Put on a black and white pic and ever so slowly rock that red drive control a little at a time till the picture looks almost normal.. If you get it to be a little \less pink then stop right there but if it starts to get a bit green or blue then try rocking those controls all back and forth till you get the bese B&W picture you can BUT BE VERY CAREFULL as there is alot of voltage on this picture tube and if your not carefull it will bite ya. Now dont be too critical as the tube is a bit weak so you probably wont get a perfact grey scale so if after a while live with it or get a new set. Good Luck.
