RCA F36650 Will Not power on Buzzing Churping when plugged in
I have an RCA F36650 YX01 ATC113CA1
A few months ago the picture would randomly disapear and come bad, then recently it made a pop and no picture and loud buzzing churping puslsating sound. If you even try to plug it in it makes the same noise and will not turn on. I replaced the flyback transformer, hoping that was it, and it still does the same thing and will not power on, is there anything else that would cause this what could make such a noise and what part might need replacing where would i be located.
The channels on the TV would start changing automatically and the problem would sometimes correct itself. This week, the on/off button does not work and I cannot turn on my set. Please help.

Hello, the HOT was not replace, i was told the flyback, and i replaced it but it still doing the same thing. Could the hot be causing the issues? Im not sure which one is the hot, there are sever transiters on the board stuck to heatsinks which one would it be?

sorry im new hear and the response went in the wrong spot, i have only replaced the flyback , i have not replaced the hot, im and not sure which one is that, there are several tranistors on the board stuck to heatsinks, i am not sure which one is the hot, is it all of them or just one?

Thanks for your help, i will try to find the part buy it and replace it, i have already replaced the fly back transformer. I guess the nest step is the hotThanks for your help, i will try to find the part buy it and replace it, i have already replaced the fly back transformer. I guess the nest step is the hot
thanks for all your help, i had the rca f36650 tv, buzzing wouldn'tturn on no picture. i replaced the flyback as well as the hottransistor, it ran great for 2 hours now the picture cuts out with a 3colored ball in the middle that disappears, looks like the windows 98screen saver color ball. The buzzing is gone no hi pitch squealing. Thepicture will be fine then it will disappear with the ball of color andgo black. Any ideas what could cause that? thanks so much for your help

I have an RCA F36650 YX01 ATC113CA1, thanks so much for your help the last time, but it seems im back where i started again. o replaced the hot and flyback and it was working great for a couple months. then the picture would cut in an out. Now it has to be unplugged because all it does is buzz and not turn on. i know the hots probably fried again, but what would cause that? I know there is a little min transformer thing next to the hot the feeds it i guess but other then that i don't know. Thanks for your help

1 Hori output Transistor most of time it is close to FBT follow pins from flyback one one pins goes to hori output B C E It will have a number on for example D1889 or C2324 Come to think of it if hori output is shorted it will make that chirping sound.and set will not come on.1 Hori output Transistor most of time it is close to FBT follow pins from flyback one one pins goes to hori output B C E It will have a number on for example D1889 or C2324 Come to think of it if hori output is shorted it will make that chirping sound.and set will not come on.

To your unit RCA F36650/CHASSIS # ATC113CA1, I posted replies to your original problem here. FBT would be the FlyBack Transformer or Line OutPut Transformer (LOPT).A ring test is check for the FBT out of circuit using an instrumentthat sends pulses to the FBT's primary circuit. Thereafter a comparatorcircuitry checks the number of damped oscillations or 'rings' producedand determines if the primary is good or not. Incidentally, it could also be the power supply unit (PSU). You could verify by doing the check on the HOT or lifting the supply to the main B+ going to the FBT and trying it. It the PSU powers up and the light lits as well as the sound comes up, the PSU is good and HOT/FBT is suspect. You might be better off getting hold of a service manual or at least a schematic diagram.
Incidentally, 13 years is a rather long time in electronics with the technology changing at such a fast pace. 13 years ago we still have a few Betamax and laserdisc players especially those by Pioneer.
Fly back transformer will cause a buzzing sound like this. Really up to you how bad it bothers you it can be fixed but it will cost a couple hundred dollars. If you can solder you can put it in yourself but the flyyback will still cost a little bit of money.
Verify service number from back of set................. Probable bad IHVT ( aka flyback transformer) and possible shorted horizontal output transistor........T.
Please let me know if # is F36650 YX01.............
Confirm service # from back of set = F36650 YX01.......... Transformer red HV lead attaches to CRT & Horiz output xistor is on heatsink next to transformer = 2SC5148 ......... Rca part # 257805 or ASTI 2078 and 237470 xistor............ Do not use a generic transistor = name brand only............T.
Apparently, a power supply weakness re-occurring........ Possible incomplete or incorrect repair the first time..... Have it diagnosed by a qualified RCA tech...... Always a possibility = IHVT = 257805 or asti 2078.......T.
Please rate this solution..........................

Hello, the HOT was not replace, i was told the flyback, and i replaced it but it still doing the same thing. Could the hot be causing the issues? Im not sure which one is the hot, there are sever transiters on the board stuck to heatsinks which one would it be? Thanks for your help
I did!!!!!! I replaced it with a bran new one!
sorry im new hear and the response went in the wrong spot, i have only replaced the flyback , i have not replaced the hot, im and not sure which one is that, there are several tranistors on the board stuck to heatsinks, i am not sure which one is the hot, is it all of them or just one?

Does anyone know how many ( hot )there are on the board that could go bad that woukd need replacing.
Thanks for your help

Was the hori output (HOT) transistor OK before you replacedFBT?
