Re: toshiba cx35f70 35"
It could be a bad solder connection on either the crt drive board that attaches to the neck of the picture tube, the video processing circuits on the main printed circuit board or the picture tube itself. If you can lightly bang the sides or top of the set to get the symptom to come/go, then it is most likely a bad connectiion. If, when the screen goes green, you see fine white lines diagnonally across the screen about a half inch apart, then it is likely the picture tube.

While i don't recall that particular pro lemme alot of Toshiba sets had an issue with the ballast boars. Basically over time the solder connection s get hot and cool so much that the joints Crack and breal. The ballast board may need to be resoldered. If you choose to try this yourself...be advised there are very high voltages inside a tv that can seriously hurt or kill you.
maybe a re-gas will last another ten years...if the leak is that small a re-gas will probably last it days out....ask the service man to re-gas it so the food does not spoil until you can save up for replacement...then just see how it goes.
If this TV is 36" it does not use the coolant. This condition could be related to a defective video amplifier transistor that is mounted on the assembly that is attach to the CRT or a dry/cristalized solder joint on that same assembly.
It could also be a defective picture tube(CRT) as well.
have 42in Magnavox plasma just over 1 yr old picture freezes
for about a minute still have sound then flashes off then comes back on does this about every ten minutes after the tv is on for
a while used to take hours before problem occured has always
How old is this TV?
It either has an unrepairable problem in the tube itself, or the
circuit driving the green gun has a problem. If the TV is at
least ten years old, I wouldn't spend any money on getting this fixed.
Did you check the supply fuses to the convergence ICs? Did you check the output resistors then i would start by replace the convergence ic first. http://home.earthlink.net/~oleg.filippov/ConvergenceFix.htm http://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-ii.html
