Question about RCA F36TF720 36" TV

RCA F36TF720YX2 TV

As soon as I plug it in there is a loud whining or chirping sound. What can the problem be, and where can I find part #'s and parts?

    The chassis # is ATC113CE2. I have seen similar problems on here and am guessing that it is the high voltage transformer or flyback? Not sure what that is, but I do know a little about electronics and could fix it if I just knew for sure what it is and where. Thanks for the help.

    Can you please let me know what is the chassis number?

    I can give you a better idea where to check if I have that info.

    Thank you.

The squeal maybe produced by the flyback, It looks like is a common defect on this chassis, but check any other defective part in the horizontal section and the power supply as well.
The fly back part # is 257805 but i would call RCA just to verify it or you can check inside the Tv's lid for that part number.
Check globalsemi.com website.
Good Luck.

RCA HD50LPW42. Sound so loud it sounds like a jet engine coming from TV (very loud whining sound). I assume this is my color-wheel, but I'm not sure.Turns off when TV turns off.


You need a replacement color wheel or have yours rebuilt since the RCA color wheels are on nationwide back order. You can get your wheel rebuilt at the following link

I have an RCA model #HD50LPW62AYX2 hdtv/dlp rear-projection set. The picture went out, and we thought it might be the bulb, so replaced it. The picture still will not come on, and there is a loud...


The color wheel can make a whinning sound for sure, However it should not continue to whine after shutting it off. That sounds more like the fan used to cool the lamp, as that will continue to run after the set is shut off. How soon does the whinning start when you push power? Let me know I should be able to help you out. DLPs are my specialty

RCA F27667 No Picture / Chirping sound


I will bet you 10 to 1 that the flyback transformer and the horizontal output transistor is bad. an no at this point the set is not worth fixing.
