Hi, I have a Proscan 36" TV, it's about 9yrs old. The unit was working fine in the morning. When I went to turn it on at night all I got was a clicking sound. Initially it clicked several times now it just does it once but never powers on. I did remove the back to inspect for obvious damage and try to pinpoint the source of the clicking. The board "looks" good. I do not know part numbers or the correct jargon but there is a white square object/part from which a cable attaches to the tube, it has a little discoloration on top, but that's it. Unable to pinpoint the source of the click, and so far have taken no voltage readings, there is a small fuse by the power cord that is good. Has anyone else had this problem and is there a probable cause? I am new to this forum and appreciate any help. lancelot -- lancelot |

There is nothing you can do but call a TV service shop and get an estimate.
This is a CTC197 chassis and needs trouble shooting possibly bad IHVT and S/C HOT. May even be trouble in the SMPS sections. IHVT = Flyback Transformer HOT = Horizontal Output Transistor SMPS = Switched Mode Power Supply. "lancelot" wrote in message m... Hi, I have a Proscan 36" TV, it's about 9yrs old.

I would guess that kip, after reading your original post, based his
suggestion on an estimation that you probably do not have the background required to fix this yourself. That's would I would conclude, and I'd make the same recommendation. If you really don't know what you're doing, and/or don't have the proper tools, you could do more harm than good (to the TV and to yourself!) Regards, - another Kip |

Well I guess my 38 yrs as a CET and working factory
service for RCA when they had factory service does not count. Not to mention I work on these 6 days a week. Get A Life Fella. kip "Mr. Land" wrote in message oups.com...
