Re:
It is probably the convergence Power supply usually mounted above the main boards below. Most of them use a STK730-010 amp that is usually the problem, if not some used a little FET instead. It seems that PCB is available probably listed as a power supply rather than a convergence bd though
Joshtv poster that the problem was probably the convergence board power supply. I tried what he said by first checking if I had that component in my tv - which I did. I looked on ebay for that part number - and bought the part for $1.30us. There were 11 pins on the power supply (had to desolder it then remove it and place the new part in it's place and solder each of the 11 pins - always be careful not to overheat the leads as you solder them - use a heat sink if you can to avoid damaging the power supply). The tv worked fine after that.

You have probably blown one of the convergence ICs. Effectively the easiest thing to do is replacing the whole convergence board, so that no soldering is involved.
If the color are separated then you need a new convergence board, or have it repair. If the controls are not working correctly then the processor could have some garbage in it, do to a small power surge, and you will need to leave the set unplug from the wall for 40Min. and it will reset back to normal.
Hi the green cross it cant move that the reference for red and blue adjustement ;just try to put the red and blue cross over the green pattern then quit/
if that doesnt work you probly have the stk-xxx ic
who control the color alignment ,are blow/
you will have to replaced and make the convergence
check if you have an auto adjustement for that most projection tv have one...
hope that help..
A professional tv technician can realign convergence or you can try to
manually realign it yourself via little knobs under one of the tvs
panels near the lamps.
Try the menu under setup, find convergence, it realigns the colors,, you are suposed 2 do that periodicly,, or when u move the tv,, should help you ,, ive got that same tv,,
Try removing the Green CRt PC voard that is on the bottom of the green Picture tube which is the center one. Then replace the fuse and see if your set powers up if it does you need a new gree tube. Just be sure the crt board doesnt touch anything while you try it. then let me know what happened, if you need a tube they arent available new any longer but I have a source for good used picture tubes,
I have the same problem three seperate colors. Did you fix yours?
