Question about RCA F32450 32" TV

No power/RCA ctc187cl

Hello, I recently had a brown out and then my rca ctc187cl would not respond. I am an experienced electronics tech and have some tv knowledge. The main fuse was blown, replaced fuse, blew again right away. Voltage regulator seemed to have several shorted pins. Replaced regulator with stk730-150. Fuse is holding now but still no power. I have a V.O.M. and I could dig my Oscope out of the garage but really don't want to have to do that. Do you have any fairly quick and easy Ideas. Thanks!       Doug

Check for 5 volts present at pins of EEPROM IC. ( 8 pin-center
front) = no 5 volts = Re-check power supply components such as AC in resistor 2.7 Ohm ?....Or 5 volts ok,then suspect EEPROM corrupted........part # 223957 ( install 8-pin socket,then re-plug in original, if that doesn't clear it, plug in
new part) Use pre-programmed after-market replacement,if you 
can get it.....Let me know....T.

Screen went black sounds of crackling and smell of burning wires


Hello
There is somethin wrong with either its EHT section or power supply section. Your description gives me very little to say a strong opinion. In both cases, it is very dangerous to handle the components at these sections. If you haven't got enough experience in handling high voltage electronic sections, never attempt to do anything with this TV. Normally EHT arcing is more common to this type RCA sets. In my opinion, get it repaired by any experienced service technician. OK.

RCA d52w20 TV will not turn on, already replaced flyback & cp150(was blown)


Hello weewilliemom,

Have you tried to see if CP120, CP140, and CP150 are good? These capacitors usually are the cause of the problem you are experiencing. I have a copy of the schematic is you need it.

I hope this helps,

Thank you,

Verify that you don't have a stuck channel up button on the panel. Next check the solder connections on the IR receiver (3 pins). Also check the +5 supply for excessive ripple. Any of these can cause odd behavior. Let me know how you make out.

Distorted image


Thats a strong possibility as the STK730-010 is the power amplifier for the convergence circuits. Its an inexspenive part to replace and easy to install. You can get a replacement IC at the following link and they provide free on line tech support for free as well as send instructions on how to replace the IC. Here is thier link if youd like it. I am one of thier on line tech supports as well as one of thier board rebuilders.

No Power RCA chassis CTC187CL


Find Capacitor C4127, this is a startup cap and will fail. Then check C4709, C4105[this one almost always goes bad] and C4404. These are good starting points. You will have to resolder the Tuner as it will coorupt your eeprom and can create a dead set. And inspect the pins a Regulater T4101 I beleive, for busted grounds. If this will not start the set you will need a new eeprom or the T4101 Regulator. The regulatore rarely goes bad in this TV!

You have bad convergence IC's.. If your not experienced in troubleshooting electronics or soldering, you should have a trained tech take a gander at the set. Its not worth risking life and limb to save a few bucks, Good Luck
