SOURCE: syntax olevia lt32hv 32 inch lcd tv. power surge now no picture

The electronics are known to go bad with these TV's, and I'm looking to buy someone's junk TV that has a good screen, rather than have to throw it out.   
(So if anyone is out there with a 532-B12 that isn't working, send me a message!)

Yours might be worth fixing - however I know sadly that parts are nearly impossible to get for these TV's, and the manufacturer is virtually impossible to contact.
If you DO manage to contact anyone (manufacturer or otherwise) who can source or supply parts, PLEASE do let me know - it's been nearly impossible for me, and I want to replace my cracked screen in my TV.
If you can't, please let me know - I'll gladly give you a few bucks at least to salvage the screen from your TV, to transplant into mine, rather than turning it into junk on your curb.

SOURCE: Soyo 32" won't turn on

The problem is the capacitors on the power supply board. There are two of them, the rating is 220uf - 250v - 105C (M). The back side of the capacitor says V9A PET. You need to remove the board, make sure the capacitor is drained, (you can do this by placing a screwdriver across the posts) Use a soldering iron and remove the capacitors. The only place that has replacement parts is at www.mouser.com, Install them, make sure the polarity is correct, re-solder them back into place. Re-connect the board and it should power back up correctly. Good Luck. Steve

SOURCE: Panasonic TX32POL1 high pitched noise

The high pitch sound is comming from a power supply transformer that will resonate (or vibrate) at the operating frequency (12-14KHz).
This is usually affordable to repair -at least worth the estimate.

The high pitched noise is coming from the Tcon board. It is not properly decoding the signal coming form the main board correctly. The only way to fix it is to replace the Tcon board. You might have a hard time coming across the part because Olevia has since gone out of business. Also, usually Tcon boards are not available sepertaly and most manufactures make you purchase the whole LCD panel of which the Tcon is included.

Monitor Goes black, or flickers on and off


The high pitch sound is coming from the inverter. It is faulty and needs to be repaired or replaced. The inverter supplies high voltage to the CCFL lamp, this lamp gives the backlight to the LCD so you can see the LCD images.
