High pitch noise after moveing? - RCA F36648 36" TV

Question edited for clarity and fix the model number, no 'o'.
Question moved from Televisions Category to maker Category.

Try and find a repairer for the board, this make does not have a maker website, so made in China. I can't think of anything on a PCB that would make a noise.

Hello,

Sorry to hear about your issue, let me see if I can help.

What type of tv is this? tube or flat panel? If tube, have you recently moved it and shook it up a little?
If panel, are you using an hdmi hookup or just regular cable from a cable box?

Be sure that your hookups are on tightly and that your cables are not tangled as well especially hdmi cable. Let me know if any of this is helpful in solving your issue or if I can be of more assistance. Once you respond I can help more, just need more information..

Thanks,
d

TV not turning on; making high-pitched sounds - Tom's ...

your rear end is going bad and they are realy exspensive, buy a new mower.

I highly doubt the main board is going bad. There is a huge difference between an electronic high pitched noise vs a scanner noise. Does the noise only occur while scanning or when parts are moving? If yes, then a scanner noise. If the noise is on all the time even when idle, then you have an electronic noise like an open or leaking capacitor.
On this particular model the seperation idle roller builds up with paper dust and will cause a high pitched noise. Like nails on a chalk board. Very simple fix. Open cover. Grab seperation assembly and pull toward the tray at the front of the scanner, it will pop loose then lift up. Make sure to pop it back into place good. Be forcefull. With the assembly in hand, clean, and lube idle roll. It is the first metal/plastic roll the paper touches at the tray entrance. Also clean the shafts and bushings for the rubber rolls. Reassemble and you are all set. Happens on EVERY I420 scanner I have seen.

try checking the tension on all the belts(fan/water pump, power steering, alternator). If loose, they'll whine.

sometimes the high pitch will come from rear bearing open door pull up on basket see how far it moves up down also ck the pump for thngs in it

if sound also goes away when throttle is released and sound returns when throttle is pressed down, then you have engine noise from car engine electronics. In older cars, this was quite noticeable when the cars had distributor caps. The electrical noise caused by arcing required for the spark plugs could be your issue. It is resolved with a noise filter which gets wired inline leading to your in-dash deck and power amp (if you have one). The filter can be found many places including Radio Shack and Crutchfield.com. First find your total wattage draw for each component of the sound system (deck and amplifier), then divide by 12 to get current draw through filter. Purchase that size filter or larger.

I have a very high pitched sound and when I move the tv it will stop for a second or two and then start again. The sound sometimes stops all together. But very high pitch sound.
