No power, 6-9 hisses then nothing (RCA model P52730CK, Chassis PTK169PCB)
I have an RCA model P52730CK, Chassis PTK169PCB. I have looked for
schematics everywhere and cannot find it. I be extremely grateful if someone could point me in the right direction. Thanks! |

This set does not have a Tripler ,it has a Flyback
Transformer and a High Voltage Block. kip -- "Watch the return E-Mail addy its false" "User" wrote in message ...

No comment on terminology or false email follow the red cable from the
flyback to the voltage block, tripler etc. it will disconnect there, as well replace HOT horizontal output transistor just in case it was taken out as well it's a huge semiconductor bolted to the heatsink just in front of the flyback. Some one went to the trouble of fixing my syntax and not offering advice on fixing the set.

Remove Red wire which leaves the Flyback and goes
to the High Voltage Block. Start Tv up ..IF high volts appear and sound OK.... Switch off TV. Replace Block. Before switching on again measure Voltage on collector of HOT if its over say 141 --143 rebuild Power Supply section before running the TV. kip -- "Watch the return E-Mail addy its false" "User" wrote in message ...
