RT2250 Shuts down on its own after a few minutes of regular operation.
Can anyone send me a pic of this, or a description of what they look like? (IE: color, size, etc.)
"Try resoldering the row of regulator IC's. They're on a fairly large heat sink at the middle of the unit."

I have the same problem and it seems like it is going into thermal shutdown as ICs 104 and 106 are overheating which are fed from C138. All input source voltages seem to be correct and I do not get any voltage fluctuation from any input on the following regulator ICs. IC 106 3.3 VDC regulator is giving me 3.3VDC as a Output Source voltage and IC 104 5VDC regulator is giving me 5.0 VDC. IC102 15VDC regulator is giving 15VDC output and IC103
-15VDC regulator is constantly dropping voltage from the time of "Power On" until shutdown which takes about 5-7 minutes. I get right around -11VDC when shutdown occurs. ICs 102 and 103 are not overheating which leads me to believe that the IC 103 -15VDC regulator is faulty and putting a load on the other regulators which are trying to compensate for the voltage drop. I plan to replace the regulator with an NTE 969 replacement.

hook up the antenna at the back and try to tune-in to your favorite radio station.
read the description at the back of your rca rt2250, how to connect your antenna.
connect it properly and raise up the antenna, put it where the signal is good.
Mine will always just turn off every minute or so after a hard shut down(ex: power outtage). I have to turn it back on and then hold the set button for a few seconds, then it stays on, until i turn it off manually, since the remote won't turn it off.
I have the same problem... I read that it can be a capacitor issue, they are on backwards. I just dropped mine off with the repair guy today... Does anyone know of a fix? Mine first had an electrical zap, then smoked, now CHCK SPEAKERS then off, and on standby...
it sounds like you gonna break the unit eventually:) now seriously, when a problem can be handled by activating physical force, it is probobly related to loose conections or wiring. if you wanna fix it yourself, take it apart and start loking for those kind of things.
