Question about RCA R52WM24 52" HDTV Projection Television

Fusible link keeps blowing out , shutting tv off

Tried replacing it several times, it works for a few minutes then the fuse gets blown. Checked circuit board, no bad leads, solder joints, or shorts, no scoring or blown components. Nothing seems a miss. The fuse I'm referring to is the fusible link t400ma on the FL231 space. Is there something I'm missing here that could be causing the fuse to be blown everytime.

Re: fusible link keeps blowing out , shutting tv off


Thanks to you, I was able to find the solution to my problem.
Have you tried using the correct Fusible Link? I noticed in another post that you said you replaced it with a 500ma instead of the 400ma. I had the same original problem as you and found the exact fuseible links at Part# 576-3960400000 Littelfuse Fuses - A 125V UL TL LL .400A . They are only 55 cents plus shipping. I bought 5 for under $10 shipped. Only took 2 days to get them. My TV works like a charm now! I too thought I may need to replace the IC's but thankfully my TV is working fine. If you did need to replace them, where were they located? I couldn't find any stk IC's inside either and the IC's on the heat sinks are all small. Just trying to be proactive, in case I ever need to replace them.

How many amps is the fuse that is located on the back of the TV near the power cord. It says T5AL/125 or 250 v. f800

Something else is going on to cause the fuse to keep blowing. Sounds like you have an issue on your power supply in the unit. Also check the outlet that your plugging it in to. Good luck!

Resolder the flyback pins as thats what causes the FL231 fuse to blow. Soldering the flyback should solve the issue you may need to replace the fl231 again

RCA R52WM24 52 in. HDTV won't stay powered on

sounds like you have more problems than just the fuse.. did you resolder the connection when you replaced the fuse. this is what causes that to happen.. fuses blown for a reason. ussally something is shorted. that particular fuse blows because it is a very small fuse and doesent take spikes in power to well. so when a intermittant connection begins to cause ossillations it shakes that poor fuse. it however sounds like you have more than that. does the led on the front flash when it shuts down.

you have a fusible link that has blown. This is what causes the convergence option no be erased from the menu. You will need to locate the blown link and replace it. They are identified by FLpreceeding the location number on the circuit board such FL221 and etc.
