RCA CTC 187CK
RCA
CTC 187CK This set (F31632ET) will "click" on, Don't think any HV to crt (arm hair test), no audio, CRT neck gets warm, but I see no glow, anyone know if this a typical RCA problem, and would a failed HOT cause ths? I have no manual or schemats for this one, anyone know of case history or famaliar with this particular model, I'd appreciate any input.... Mark G -- "The plastic tranny is almost here!!!" |

How about starting with standard tv set troubleshooting procedures for dead
set and go from there. Post some real troubleshooting information and where you wind up unsure of which direction to go for hints.

Angel's Dad:
You gave us almost nothing to go on here...... you are our eyes and ears.... we need at least some basic technical and definitive test results and troubleshooting observations with at the very least a DMM or VOM. My best suggestion to you is for you to go to the website for this newsgroup at http://www.repairfaq.org/ There with some searching you will find a wealth of information that will help you to do some initial troubleshooting, voltage readings, component tests, etc...... THEN, you will be able to post some pertinent information that will probably result in helpful repair suggestions. Be sure to heed the safety warnings in the repairfaq or you may get more damaging results than just the hair on your arm standing up.... be very careful..... dangerous and lethal electrical shock hazards can still be present even when the television is turned off and unplugged from the AC power.... -- Best Regards, Daniel Sofie Electronics Supply & Repair - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - "Angel's Dad" wrote in message RCA CTC 187CK This set (F31632ET) will "click" on, Don't think any HV to crt (arm hair test), no audio, CRT neck gets warm, but I see no glow, anyone know if this a typical RCA problem, and would a failed HOT cause ths?

OK then, I'll go check that site out,
I measure voltages on pin 1 or 2 of the flyback, and I get popping sounds thru the spkr, and my meter pegs out, there is a small glow off the CRT neck, so the heaters are working, I mess with the screen control on the flyback and ya can hear it changing pitch(have to get ear close to flyback to hear it), also, once its on, it won't cut off unless ya unplug it....... |

Your troubleshooting approach needs some technical enhancement..... be certain to go to the website for this newsgroup at http://www.repairfaq.org/ You will find a wealth of troubleshooting tips, repair procedures, component testing methods and IMPORTANT safety information. Do some searching and learning in the repairfaq site, perform some more in-depth technical troubleshooting and testing and if you still can't get it going, post your renewed technically oriented troubleshooting results with some more details, meter readings, and component testing results. Good luck.... and be very careful. -- Best Regards, Daniel Sofie Electronics Supply & Repair - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - "Angel's Dad" wrote in message news:1068503245.130576@rh9cache...
