RCA CTC169bj5 Chassis cycles on off on power up
Like the subject says plug it in and push the power button and it
tries to start about 4 times and then quits I have replaced the following : C4102 C4108 CR4118 and my standby volatage at Cr4116 is 146 and at cr4118 13.1 and when I try to power CR4116 doest change much maybe .5 volts and CR4118 goes to about 14 and then it resets and starts again about 4 times before it stops and the voltages go back to standby readings i can find no other visiable damage set started this problem it would come on and work fine but if you turned it off it would not start again Any help would be greatly app. Thanks Mike |

That chassis uses the seperate HV divider off the 2nd anode lead. High
failure item. Remove the anode cap and disconnect the feed for the divider ...then see if it comes on . If it does , shut it down..... Originals are NLA.

Jeff forgot to mention to ISOLATE that high voltage lead because if it does
power up there will be about 30 kV on it. It'll either give you a hard on or make sure you don't get one for a while... Having a bad day and want someone else to have one too, Jeff, or just up too late posting? LOL Leonard "Shoreline Electronics" wrote in message et...

Here is a few things to check.
Check R4719, Q1914, R4713, R4704, C4141,C3124, Q3102 (SMD), RCA CTC169 DEADSET BUT SOUNDS LIKE IT TRIES TO COME ON AND THEN SHUTS BACK DOWN. CHECK/REPLACE T4401 FOR SHORT (OVER CURRENT)-UNSOLDER PIN 1 OF FLYBACK-PUT 100W. BULB FROM PIN 1'S SOURCE TO GROUND RCA CTC169 SET SHUTSDOWN AT TURN ON AND TRIES TO START-UP (3) TIMES CHECK/REPLACE C4401 |
