Question about RCA G27647 27" TV
I am hoping someone knows a common problem with this chassis.....I have changed the jungle chip, but no go. Color comes in once in a while but 3.58 freq. is not in sync. Then goes back to great grey scale. I dont have a manual. Have also checked chroma buffer q2850 [smd] Anyone?....Anyone?

First thing to check would be L401. Its a small coil from the secondary side of the horizontal driver transformer to the Base of the horizontal output transistor. Not a solder problem, You must take it out and scrap off the leads to remove the excess enamel paint the reinsert and resolder. Also check connections on the driver transformer too(horizontal). Next check for bad solder connections on the flyback transformer too. Good Luck PS please dont forget to rate this thread.
