pkt195db convergence board barbecue
Greetings all,
I'm working on an RCA 52" Model P52830BL, Chassis PTK195DB. Came in with a blown main fuse, an obvious burnt R19233 and no convergence (upon powering up with 200W bulb in series.) R19233 being on the collector of Q19230 I figured it'd be toast too (some spurious power surge perhaps?) but it wasn't and everything else looked OK, so I just tried replacing R19233 (forgot to put the bulb back in series -oops-) and it promptly toasted R19233 again, as well as R19207 and R19209. I don't have a schematic, so I thought I'd run it by you gurus in case anyone had had a dozen or so of these with a similar or same problem. Thanks in advance. Kevin |

OK, so no takers. Could someone maybe give me the values of R19207 and
R19209 for this chassis? |

Sounds like time to go buy a SAMS Photofact for your set?
