Question about Samsung PCJ534RF 53" Rear Projection Television
This sounds like a convergence problem which means that your convergence amps have malfunctioned. You can change these out yourself, however you will also have to change out all of the biasing resistors connected to the amplifiers. To do this:
1) Unplug the TV and then get a schematic of the TV I use http://www.servicemanuals.net or http://www.manualsparadise.com
2) On the schematic locate the STK329-xxx series IC packs (usually attached to a large heat sink)
3) determine if the STK329s are 110, 120 or 150.
4) if the STK329-xxx's are 110s replace with 110s (forget that upgrade stuff it is a hit or miss game that I don't believe you want to get into), if they are 120s replace with 120s and so on.
5) Now to replace the STKs: remove the module from the TV and unsolder the old STKs along with the bias resistors, and replace them with the new ones (be sure to apply heat sink paste to the STKs when attaching them to the heatsink)
6) make sure there are no short circuits form your soldering job.
7) Reinstall the module and then turn on the TV.
8) do an auto-convergence test and then things should be back to normal.
Now if you think you can do this have at it, if not I would suggest that you have it done by a qualified TV technician.
I hope this helps,
