Picture Jumps/flashes for first 5 minutes

I have a Toshiba 36HF72 that when turned on for about the first 5 minutes has a horizontal flashing/jumping/jittering that "tiles" or scrambles the picture. After it warms up the picture has slight vertical (up & down not side to side) wavy lines throughout the picture but mainly noticable at the top. The picture continues to flash every once in awhile (especially when the vcr is playing). The horizontal & verticle deflection sections have been resoldered as well as the power supply section. Freeze spray has no effect on the board after warm up. Tapping, shaking, or flexing the board has no effect nor does probing with a plastic stick. The problem seems to be gradually getting worse. Any suggestions would be greatly appreciated, Thanks :-)

Re: Picture Jumps/flashes for first 5 minutes

How are you able to get underneath the main board so that you can detach the main part of the silver "box" from the board so that you can unplug the module? this is where i'm stuck. also, the solution lists number cx241 twice but counts it toward the total of 11 caps to replace, can anyone confirm this?

TV video/audio problem

It may not need repair or replacement.
Unplug the set at least overnight; the CRT (picture tube) has voltages that may be as high as 30,000 volts and take time to bleed off. Believe me, it stings if it bites you.
Remove the rear housing of the set, then use a clean (preferably new) 2-3" paint brush to whisk away any dust deposits you see. This works best with the nozzle of your vacuum cleaner near the area you are cleaning.
The problem you describe can be caused by an accumulation of dust that is picking up moisture from the air and temporarily creating a path for high voltage to discharge which can cause all kinds of strange occurances such as you describe. The warmup of the set dries out this moisture removing the discharge path.    If you don't remove this dust buildup, it will eventually damage the high voltage circuit if not others as well. That high voltage is a healthy static charge and wasn't designed to supply a lot of current which it has to do when discharging.

Problem with tv

Could be a horizontal output fault, faulty power supply, a simple dry solder joint or HVT. If you can hear arcing or smell an ozone odour, it will be the HVT which may cost a bit.

Without knowing the actual cause, it's impossible to say how much it would cost to fix it.... could be anywhere from $50 to $250 etc

Best to have it checked by a technician and get a quote to repair... then decide if you think it's worth it.

Toshiba is generally a reliable brand, so if you were happy with the picture quality before the fault occurred, it's probably worth repairing.

Takes about 5 minutes for picture to appear... Then every one to two minutes the picture disappears. It comes back on for 1 - 2 minutes then repeats. When set if first turned on, the stereo/stand-by light (red) flashes on/off until just before picture first appears .if your tv is very old than it might be due to crt getting weak crt base loose loose contact in power supply thanks

Toshiba 32A43 Horizontal Bars, pop, no picture.

First of all, there is no such thing as a "high power flyback converter". There is a flyback transformer, but if it was bad you would have absolutely no picture at all. The fact that you dont even know what the basic components are suggests that you should not be "diving in" to someone else's TV. Do everyone a favor and allow an experienced tech to service the set.
