Re: Screen keeps flashing on and off
If the sound goes off too then there are bad solder connections, if it just the picture then the picture tube is getting weak, some times a picture tube rejuvinator can bring some life back for a while.

The issue here is the "Format" or "Ratio" of the screen. Currently, it is set to Standard Format or a 4:3 ratio. It may also be set to 480i or 480P scan rate.
You should change it to Wide Screen or 16:9 ratio. Additionally, you will want to display High Definition images by selecting a scan rate of either 720P, 1080i or 1080P - depending on which choices are offered by the TV. Typically the remote will offer a choice of Format. It is possible that the source device (cable TV, DirecTV, Tivo, etc. has a command to cause this too. In any case, the TV, and other source appliances must be set to Wide Screen / 16:9 and 720P or higher to veiw full screen, HD images.
You need to check power rails and look for bulging capacitors near heat sources. I hope I have been of help but please do not hesitate to ask if you have any further questions. I appreciate your vote if you appreciate my reply.
hi just by using a 3-2 prong converter which is found at a hardware
store can take away ur problem. It takes the plug into the wall from a
3 prong plug to a 2 prong plug and is supposed to work. try it and let
me know if it works....
Hi, tubes getting tired, band-aid fix you can do is remove back of set and turn up(clockwise) the screen control( small black plastic control mounted on side of flyback transformer, do not turn the knob marked focus) until you see a whole bunch of white lines across the screen, then turn same control counter-clockwise until all the lines go away, try several different channels to be sure all the retrace lines are gone, you`ll get up to 1 year more use out of it, than she`s done, good luck, BMW Rider
Sounds like you have a problem with the blue gun in your picture tube or its drive circuit.
You might remove the back cover and gently tap on the neck of the picture tube using a plastic
screwdriver handle while watching the screen in a mirrow. If the picture flashes back on or on and off then the picture tube is the problem.
If this is a projection tv you have three separate tubes : red, green & blue.
you'd need to tap the blut one.Gently!!!!
