We have only had the TV now just short of 2 years. We were sitting there watching it and the screen went blank. It has a slight faint line across the middle of the screen. I have tried it in other TV points and still it doesn't work. We have had this problem once before about 1 week after our 12 months guarantee it did the same thing. We got someone to repair it and 8 months later it has happened again.
I dont know what any of the numbers meam so I hope something makes sense to you?

Re: My TV Doesn't have any picture???
This is what is known as frame collapse - which means there is no vertical deflection applied to the tube.
Please do not continue to watch the set in this condition as it may burn a horizontal line in the middle of the screen.
The most likely cause is either bad solder connections to or failure of the frame vertical output IC.
Please rate the assistance I have given - I hope it is useful. If you call a serviceman and tell him its frame collapse as this type of repair is not for amateurs - voltages in television receivers can kill.

I WOULD SAY NO ! THE PICTURE TUBE IS PROBABLY AS MUCH AS THE TV IS WORTH. i had a very nice sony trinatron tv. the picture tube whent on it at about 5 years so I CALLED FOR REPAIR AND THE PICTURE TUBE WAS 2-300 DOLLARS. good-day !
1) When the picture "stops", does the standby light blink at all?
2) Can you post the model number please?
Some of these sets are known to have problems with the picture tube as it starts to age. There are some workarounds for this that can extend the life of the set for a short time. Without the model number though, I can't confirm that this set is in that catagory. Please supply responses to the issues above and we'll continue from there.
This problem sounds like a short inside the picture tube itself unless a driver transistor failed that drives the red gun in the CRT. You may have to take it to an authorized repair facility if the picture tube is still in warranty.
Picture tube failure is rare problem. Your problem is powersupply failure and short circuit in deflection area. This is quite common problem. My sugestion is before you got this problem picture clarity and color clarity is better perfomance in your satisfaction means repair is better. Otherwise replace it.
