Sometimes when shorts or sparks occur in the viciity of the flyback. compnents take a hit. if i had this set in my shop i would first check what is called the horizontal output transistor. this transistor is directly related to flyback and i would suspect it to be shorted. certain capacitors and diodes also can short under the same situation. And theres a possiblility that the flyback is bad

Vertical hold (picture squashed into 100 mm wide )


This only happens on tube TV's. I am assuming that you are dealing with a flat screen tube TV, not a flat panel TV.
Your issue is that the voltage on the vertical sync is low. This can be caused by a cold solder joint, or a bad transformer.
A "cold" solder joint. Just means a solder joint with poor contact. This can happen over time, and it's pretty easy to see. The solder will look dull grey, and have a brown greasy substance on the surface. you can just heat the solder with your soldering iron to remelt it, if this is the case.
Unless you have experience with repairing tv, I can't give you any more advice, without suggesting that you do things that could hurt you.
If you are going to open the tv yourself, don't do so without leaving it unplugged for 24 hours minimum. Most tvs discharge all power when you unplug them, but not all have this safety feature, and the flyback transformer has adequate voltage to kill you.

Convergence nightmare


If this is a ITC222 chassis then you need to check the fuses that are near the flyback. I would also unsolder all the pins on the flyback and re-solder them as the factory lead free solder tends to crack and cause issues with the convergence. Re-solder it with common 60/40 solder you can pick up from Radio Shack or other places.

Rca hd52w59 convergence problem


there is a special fuse on the power deflection board. when blown this causes the processor to think it a crt tv. The fuse calle fl231 is a small brown rectangular fuse in the middle of 3 just like it next to the flyback transformer the big black thing with the large red wire comeing out. ussally it blows because the solder connections on the flyback. WARNING high voltages are generated by flyback. be careful please

JVC 31" TV Vertical Screen Jumping


I've heard this is could be a cold solder joint and am looking for advice on which IC to re-solder. 1 whatever you have heard is correct as whenever you smacked the lelt side it works fine. 2 you will have to check loose contact in vertical section. your vertical ic might be located at the left side of the tv. 3 check any connector is loose near vertival section. 4 any preset is loose in vertical section. it is a simple problem if you are not technical person please get it done by tech person. as your tv is old & if it is done by tech person tell him to replace all elrctrolytic capacitors in vertical section. good luck.
