Re: now it squeals when turned on

That is a CTC203 chassis that is VERY difficult to estimate without seeing it... The "squeal" symptom you described indicates that the HOT (horizontal output transistor) has shorted. (Q14401 RCA p/n#242224 (2sd2578)). But I would not stop there... Check also: Q14101 RCA p/n#244223, R14107 p/n#244214 (43 Ohm 1/4 Watt) and really go over the underside of the board for poor solder connections. Tri State Module can rebuild that board to like new for $100.00 dollars plus shipping. and even if a shop locally did the teardown and re-assembly that's a lot cheaper than the cost of a new TV of comaprable value. Hope this helps! Bill

After tv is on for approx 20-30 mins it starts to make a loud high pitched squeal or whine. once turned off for approx 10-15 mins can turn it back on for another 20-30 mins before squeal will return....

Sounds like a problem I had with a Polaroid t.v. Take the cover off the back and look for capactors that are buldging on the top. The top should be slightly concave. If they are convex at all, you can buy new one at Radio Shack and replace them for under $5.00

Tv turns on every night at 7:00 and turns off at 8:00 by itself. If we are already watching tv it defaults to a specific channel at 7:00 pm automatically.

Dear customer,                Check you tv's sleep timer and scheduler settings and disable them. thank you.

TV Turning on and off by its self

You have problems with a condenser that allow the power supply to maintan an acceptable level of voltage in order to keep the TV on. take to a tech to be fixed. unfortunatelly, this problem needs a tech to take measures in the circuitry to find the component that causes the problem.

TV turns itself off after a few seconds, no picture at all

As far as fixing goes, you might as well get a new TV... Unless its a LARGE EXPENSIVE HOLY $%^# TV, It will cost more to fix, than to just buy a new one, unless its under warranty, which being an older model as that (or so im reading) It may not be covered.

Try unplugging the TV, and while unplugged, hold down the power button for a full minute (yes, with the plug NOT in the wall) after a minute, plug it back in, and try. Its a hard reset. If it still does not work, and you've tried different outlets, It's probably a repair issue, and you'll need to get someone to fix it, or just junk it :-/
