Our tv just started having a fuzzy image and the auto focus function aborts during the red color alignment. is there a manual alignment I can do to fix it.


What does this fuzzy image look like? Does it have ghosting shadows. Of course it is possible to align red manually from the convergence menu. But first lets confirm that it is indeed a convergence related problem.

My TV looks like it had permanent 3-D. Red Ghost


hello it sound like the convergance ic may be the problem these chips sit behind the tuner board connected to a metal frame called a heat sink they are soldered in. also you will have to check the resistor in front of the chips also check the 2 capacitors at either end it would be best to get a quote from and engineer good luck

Ghost image arcs over picture


This tv have a convergence problems,it dead.The covergence board the 2 STK convergence ICS and some or all it resistors are dead.All these parts must be replaced to solved covergence problems.The shop will cost U $300-350 for parts and labors.

Convergence


Did you remove 1 leg of each resistor out of circuit when you checked the resistors? sounds like thier is still one resistor open or maybe one of the new IC pins need abit more solder.

Color Issues with red ghosts on screen


The suggestions listed would be relevant for 'Ghosting' by itself, however you mentioned you tried to use the crosshairs to line up the images4.gif, which implies convergence - red/green/blue image separation and/or distortion. NONE of the solutions mentioned were anywhere close to the fix for this problem - this us usually cut and dry; convergence circuit failure. Generally, STK ICs are used. (Common parts are STK392-010/020/040, STK392-110/120/150/180, etc.) Most times replacing BOTH of these chips will be enough, sometimes there will be a blown fusible resistor and/or burnt resistors near the chips themselves. If you don't implicitly know exactly what I'm talking about, don't attempt it - take it in to a repair shop. For in-shop repair, this would NOT exceed $250 (EVER) at our location, unless there was more damage done, which is a one in a hundred situation. Good luck!

Red and Green picture with ghost images


sounds like the high voltage transformer arc or one of the picture tubes arc causing the convergance ic to go bad
you can try to replace the IC heres a site to help:

but you still may have a arcing problem.

Sony KP-57WS500 Pictures problem


Your Convergence Correction Amplifier ICs have gone bad (STK329-110) They must be replaced along with the biasing resistors

www.electronix.com has the parts you will need plus I would suggest that you have a qualified TV repair person do the installation for you.

Make sure the traces on the circuitboard are good and that the solder connections are good.

But the ICs and resistors need to be replaced.

Thank you,
