Waves on top part of my picture when tv is on

Change input device to some other like a DVD player. Look for loose contacts in RC jack, cable, sockets. Look for any jammed buttons on TV or on remote.

Switch off TV, switch off power, remove plug and wait for 48 hours and retry.
If problem persists, call in a qualified service technician.

Tv have convergence problems,it dead.Colors lines R,G,B don't aligned.The tv convergence board is dead.The 2 STK convergence ICS and some or all it resistors are dead,these parts must be replaced to solved the tv pictures covergence problems.The shop,will cost u $300-350 for parts and labors.

i think there are som ic,c broken.
you have to replace them,then you have to adjust the convegence again.
the ic,s are stk 392-10,also check r7716,7721 and7711

The capicators in the hyperboard have failed. An esy fix if your patient. Otherwise I offer a repair service. Let me know.

That symptoms are due to failure of convergence out ICs in your TV that will be replaced to get correct converge picture on front screen.

There are 2 big black IC mounted on big aluminum heat sink and number would be written on as STKxxx, these 2 ICs will be replaced.

If you want to repair TV by yourself then confirm model number of TV to provide you more info or call local tech to replace said ICs.
Thanks.

you have a fault in the power pack, ths can only be repaired by a tv engineer..

This is a common problem usually seen when playing copy protected tapes. The part of the picture affected is normally off the top of the screen. Sometimes the problem is also due to the VCR itself and differences in tapes. It's also possible for the TV itself to be causing this, although you would probably also notice this flag-waving (that's what it's called) on regular TV viewing if that were true.

Sometimes increasing the height of the picture can push the affected area off the top again. But this can also cause you to lose part of the picture you want. Also, the height adjustment may be difficult to find as it's not something normally used. On some TV's it's a small pot somewhere on the board, but most newer sets have electronic adjustments through a service menu that you need to know how to access.

I'd suggest trying another VCR first and play one of the tapes you know shows the trouble. That might be all it takes. Then consider trying to increase the picture height if it's just a small bit at the top of the screen.

Any kind of wave form usually is cause by a bad filter, the question is if it's in the powersupply or horizontal section. I would first start with PS. Look for bad capacitors.

is the waves running horizontal?
