RCA Pro Scan M:PS52652 Chassis : PTK169PDBS

[Chris W.]

set seems dead. checked fuses and they are good. tech had looked at
set before i got it and said the coolant had leaked, but there is no
coolant inside any where on any components or boards. any help would
be great!

Thanks,
Chris

May be time to have an RCA Service Technician have a go at it, have them
indicate to you where the fluid could have gone and the effects. Seen a few
of these that the fluid goes right into the deflection - HV circuits.

Looks like it is time to call on an experienced and trained technician,
preferably one with lots of experience on the ctc195 series of chassis.

Without even minimal basic troubleshooting information, no real help of any
kind can be given. The information you have given says you have a dead set
that needs repaired.

UPDATE ....
there is a clicking sound from the HV block when i press the power
button. it keeps clicking if i hold the power button down. hope this
helps.

probably a bad HV block; pull the flyback to block lead (it's labaled near the
block) and position it out the front of the cabinet as far away from everything
as you can manage; then turn on the set (briefly); if it powers up, even for a
second or two, you've found the problem (the block). Don't buy the generics,
use only the RCA part. You'll also need to check the power supply voltages, as
this chassis frequently has problems with some capacitors, and a diode.

upon further diggin i found the R712 and R713 resistors were burnt and
cracked. does any one know the value of these so i can get
replacements? they were located next to the output trans on the left (
if looking down on the board).
