Re: Cant realign the color on my tv

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

Re: Cant realign the color on my tv

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.

I have a RCA Home Theatre TV Model# P46813BL and we are having trouble congiguring the screen. We had a fuse blow, and have replaced it, but now our picture is off. We have used the TV remote to pull up...

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.

Help with RCA projection TV P46812BL (chasis ptk195AA)

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.

Here you can buy a replacement convergence board, just select your model.

Let me know if you need further help.

Color convergence out of wack

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.

Hello Phyko14:

The convergence needs to be realigned, that is something that a repair center will need to do.

No Power

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,
