Question about Pioneer SD-533HD5 53" Rear Projection HDTV

Fuse keeps blowing

Our television suddenly stopped the other day. I replaced the fuse and it keeps blowing when you attempt to turn the set on. Is it worth trying to fix or time to dump it? I'd like to attempt to fix it myself, I'm fairly familiar with it - I replaced the IC's about 6 months ago. I've asked around for names of those who repair, but even a friend who works at an electronics store said there's no one around here who messes with them anymore. Any suggestions?

Re: Fuse keeps blowing

It might be worth fixing but you will have to call a tech out to give you and estimate. When the fuse keeps blowing that means it is drawing to much current so it could be the power supply and that might not be that expensive. You best option is contacting pioneer and asking them where the closest authorized service center is.

Keep blowing the main fuse.

To which circuit section did you replaced the fuse? Main power retulator? Just understand, the fuses are used to protect the circuit and TV from any short circuit or over voltage. Without any one of these, no fuse will blow up. If it was due to over voltage, the set should work after a fuse replacement. But here, the fuse blow up again, means, there is some thing shorted component/s. Check which component is shorted, and replace it, before replacing an other fuse. One more thing to say is, never insert a fuse other than specified. The voltage and ampere specification to fuse, will be marked at the circuit board, very near to the fuse clamp. Insert a fuse of same rating only. Using other fuse, rated higher ampere rating, might make things worse.

Magnavox 37MF437B/37 keeps blowing fuses

Either a short somewhere---which fuse? The one at the power cord or what?

Other possible reason is wrong fuse----many of the fuses in these sets are special-----if you go and buy some Generic ones--hardware store or Radio Shack the fuse even with same amperage/voltage rating may blow at turn on instantly for no reason------

My HD rear projection television keeps blowing a fuse. Everything was working well last night then it blew the fuse I replaced it and it blew again.

On these sets if you replace a fuse either you have a short OR the fuse is a generic one------replacement fuses from say Radio Shack will even if correct amperage and voltage blow for no reason-----most of the fuses in these sets are actually thermal or slow blow types.

With the set unplugged take a meter and check both sides of the fuse to ground in the set. If the fuse that is blowing at once is the one connected to the power cord it is likely incorrect fuse or generic junk fuse was used to replace it.

ATTn SD Tech: my 65" Mitsubishi keeps blowing the

1,2 means no error found. To confirm turn set off and unplug and and turn back on, when it fails try the self check again.

Where did you buy the replacement fuses? Radio Shack?

Some of these fuses are special and the poor ones which are generic will pop for no reason sometimes; examine original fuse and holder for correct amperage and type of fuse used.

Replaced the fl231 fuse tv worked for day now blown again and tv keeps shutting off what do i check now

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

The fl231 fuse blew 3 days after i replaced it so problem is obviously steming from somewhere else. I keep seeing solder joints that need to be resoldered, can you elaborate.

The reason the fuse keeps blowing is because of bad solder joints on the flyback transformer,resolder all flyback cnnections and you should be good to go.

I am trying to locate the fuses in the back of the tv.

That set is equipped with self diagnostics. After attempting to turn it on fails try this...On the front of the set hold down the MENU and INPUT buttons at the same time until the green LED starts blinking. It will blink a two sequence code. As an example a 1 - 2 code is no problem detected. Repost code and I might be able to narrow things down for you. BTW fuses in these units do not blow for no reason. If you do find a blown fuse a replacement would just blow again until the short is found and fixed.

My TV doesnt turn on. where is ther fuse?

The fuse should be near where the line cord is attached to the power supply inside the TV. Be careful as there is a possibility of some DC voltage present from filter capacitors still holding a charge, long after the set is unplugged. If a fuse is blown and blackened, a new fuse will probably do the same when the set is plugged back in. Make sure you use the exact same rated fuse. IF the new fuse blows right away, do not repeat the process, it will only cause more damage. Good Luck.
