    I have the same problem, tv "poped a couple of times while watching over the past few weeks, tonite it poped and went off, just a whinning from the center of the main circuit board, when you unplug, the whinning noise sounds like an electric motor winding down....



    I saw one post of a possible hort. transistor and a flyback transformer, but does anyone have a schematic? Or directions? I am a ham operator and very good with high voltage circuits, so I want to try to go at this one, TV shops will just laugh and say to go get a HD which I don't realy care for, I like my 900 pound tube tv! LOL!

This set is famous for this. It could be the main power supply has a short in it but most likely the Horizontal output transistor is bad because of a bad flyback transformer. Not really a job for a novice to attempt as there is alot of High Voltage present on the picture tube. Good Luck

My Braun 7570 has suddenly stopped working, but there is a high pitched whine when I switch it on.


This sounds like a battery problem. The likely remedy is to replace them. You will find batteries for your shaver at shaveroutlet.com

High pitched whine/sometimes TV won't turn on


The power supply on this model will whine when it is shorted or overloaded - the set would have to be brought in to determine exact cause.

RCA F32650 production May 2003. Was working fine. Turned it on the next day, got no picture and a high pitched whining noise.  Please let me know what I should do to fix it.


If it weren't for the high pitch whining noise. I would say it probably is an internal fuse inside the chasis. It is rated at 1.5 to 2.0 amps. With the whining noise it sounds like a trouble shooting bench
job. Problems occur when a electrical/electronics device is turned on and turned off. Inrush voltage,
when it is turned on, can go up to three times more than normal. This also happens at turn off. Solid state components usually fail at this time. I don't feel that this is a problem that can be fixed in the home.---BBB

High pitched whine when the motor starts


Had the same problem. It quit within about 5 seconds after turning the TV off. Replaced the color wheel and the whine is gone. The picture also looks brighter, which may be due to dusting the projection lens with lens-cleaning compressed air (from a can). The color wheel was about $100 from Samsung parts and it took less than 3 hours to replace. See http://www.jangro.com/a/2006/07/24/samsung-dlp-replace-color-wheel/ for good info, and be sure to read the cautions.

Power light comes on, followed by a high pitched whine


Hi, If after trying the TV again later and problem persist, repairs are in order. A high pitched whine is an indication of a fault at the horizontal section of your TV. The horizontal provides the high voltage for the picture tube. Your best bet maybe to seek the services of a qualified professional TV repairman since this involves component level repair, soldering/desoldering, use of soldering iron and VOM (testers) and knowledge of circuitry. Good luck and kind regards.
