MY TOSHIBA 32 INCH TUBE TV I BELIEVE HAS A VERTICAL IC PROBLEM THE REASON I SAY THIS IS WHILE A SONY I HAVE WAS GETTING FIXED I MENTIONED MY PROBLEM TO THE TECH AND HE SAID IT COULD BE THAT OR THE YOKE THE PROBLEM IS MY TV IS SHRINKING FROM THE TOP AND BOTTOM SQUEEZING IN TO THE CENTER WOULD I BE CAPABLE OF OPENING UP THE TV AND BE ABLE TO FIX SAME
> WOULD I BE CAPABLE OF OPENING UP THE TV AND BE ABLE TO FIX SAME
Possibly; vertical deflection ICs are more available than some other parts but to identify it, you will either need knowledge or a service manual with schematics available.
There is a chance that it is not an IC but a failing capacitor.
The deflection voltage is derived from a tap on the flyback, rectified and then filtered.
If the cap that does the filtering is losing capacitance and gaining losses, this can cause your vertical deflection to gradually shrink.
You will still need a schematic to find which tap is used so you can trace it to the rectifier and finally the filter cap.
Do a search on your model number and the phrase "service manual" in quotes; I've seen a fair quantity of these available on line.
But, not generally from the manufacturer since they mostly insist on supplying this only to 'authorized dealers.'
The symptoms you describe are actually 2 different issues. The easiest way to address this is to attack the vertical problem then if the other still exists, we will address that one. I should be able to provide you with details, but I will need the model number. Please update this with the model number and further details and instructions will follow.
Thanks,
Dan
