Color convergence problem

If you follow the instructions on the other thread, you should be able to resolve the problem. Try the simple stuff first. Resolder the pins of the convergence ICs and see if that alone resolves the problem. Sometimes that is all it takes.

Keep us posted.

Colors out fo alignment

The convergence circuit is having a problem. This can be either bad connections at the pins of the convergence ICs or defective ICs. These are large black ICs attached to a heat sink and should be marked STK-XXX. If you can solder, try resoldering the pins of these ICs first. If that failes to resolve the problem, replace the ICs. The should be no additional alignment necessatry once the ICs have been replaced.

Sprayed Screen

Take a look at this relevant post:,p211196/RCA-P61927-61-in-Rear-Projection-Television.aspx It's possible that the cleaning agent in the spray has dissolved the screen. If it is the lenticular lens(the vertical lines) there will always be permanent marks from the spray until it is replaced. You can try a toothbrush, dry and carefully scrape the material out of the grooves. there's also the Endust Product made just for this type of thing, It's called Endust for Electronics, and I heard it works like a champ. Another option is a dry-cleaning solvent, trichloro-ethane, which you can find at many hardware stores. This will wipe crayon marks right off of glass without any scrubbing at all. Plus, it's harmless to most plastics. Also heard of a product called Tough and Tender, that should be ok with a screen. you better consult JVC on any material you plan to use though. Major problem is in case the spray dissolved the screen. Don't be hard on the kid, encourage him and he might be a great graffiti artist ;]
