Question about RCA F32450 32" TV

1 Answer

Lost my picture

I turned the tv on and shortly after I heard a pop and lost the picture. This happened to me before on a 27" sharp. To fix the sharp the tech had to replace the horz. control. I fell it's the same thing this time around. Your thoughts please? I do a lot circuit repair on pc's and consoles, just not tv's. So I feel confident that I can fix this problem if I knew what/where to repair/replace. Basicly if you can tell where to do a continuity/Ohm check and what the rating is, would be very helpful. Also how can I get a digital copy of the schematics for this model. The tv is an RCA 32" M# F32450 CH# ACT113CA1 Thanks RDTownsend75

Re: Lost my picture

This modelis avail on a PDF file from Sams photo facts for $27.50. First thing you wanna do is disconnct the horizontal output transistor.. Measure the base to collector or emitter to collector for a short. If it is shorted then the high voltage transformer(flyback xformer) is the reason it is bad. Its part # is 257805 and cost about 40 bucks at most RCA parts houses Also these models a small coil can cause the horizontal to blow out and its the small coil that conects the horizontal output transistor's base to the horizontal output tranformer secondary winding. Sart there first if you dont get anywhere please contact us again and post the pdf and we will look and ask you to do more checks. Good Luck

Picture wnt out suddenly without any symptoms

My picture would go out after several minutes but I still had sound. I took the rear cover off and blew all the dust off with compresed air.I did this for a few times over several days nothing happened.I also took off the rear circuit board that attaches to the tube with a round pin socket and blew that with compressed air and put it back on. The TV has now worked for two days without the picture going out. It worked!!!!!!!!!!!!!!

Screan turned a shade of purple

I believe you have lost the green channel leaving only the red and blue. It could be an internal connection like a solder joint or connector, or it could be component failure from the CRT to an adjustment pot. Being the set is ten years old it wouldn't be worth spending a lot of money on it. You can buy a 27 inch TV now for almost what a repair would cost. If the picture was very good before this probem you may try to get it fixed cheap. Otherwise it probably wouldn't be worth it.
My 27 inch TV's (A Sony and a Sharp) are pretty old and I would fix them myself if the picture tube was very good.
This may be a very good time to buy considering the discounts being offered. ;-)).

This problem sounds like a short inside the picture tube itself unless a driver transistor failed that drives the red gun in the CRT. You may have to take it to an authorized repair facility if the picture tube is still in warranty.

Tv popped and stopped

The over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits. It's best to have a Certified TV repairman look at it. Generally when this happens, the TV keeps getting worse and repairs can get expensive. If the repairs are over $300, then I would look into buying a new set.

Sony has a code for those blinks indicating the problem area. Count the blonks till the pause then google Sony blink codes for the area to fix.
