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.

Pioneer sd-643hd5 fuse issue


The fuses may not be your problem--I have fixed several of these---The large power board is on the right side as you look from the back?

Lots of these sets develop bad solder connections on that board--several sites on the internet offer to have you remove and send them the board to resolder--this set used lead free solder and after some years has problems--a few I have opened had clearly broken solder joints--I usually in this case remove the board(mark all the many plugs and make a diagram) and solder almost all of it by hand----usually fixes this kind of trouble.

I do this here for free so if this information was helpful give me a vote here....I am here to help people.

Power problem on Pioneer Pro-700HD


The failure is not on the power supply but the convergence amplifiers STK ICs have the 24 volts shorted.
If that fuse is blowing, de-solder the convergence ICs and put a new fuse to power up the TV; you should see distorted video when the TV powers up and the fuse should not blow.
The service manual migth not help much in this case since the failure is easy to pin point.

Good Luck.

Toshiba 50H81 TAC0151 Blowing Fuses, I Need schematic


Well without the schematic, knowing Toshiba they have alot of convergence problems, so see if the fuse blown in the convergence area, if you you may have to replace convergence amps. These are the big STK's. Most of the time there was a color problem with set before going out. If no problem with this on your set then look in the HV area Hor. and Ver. area. Hope this helps!

Replace the Power Supply switching transistor, If a CTC195 chassis it is the Q14101. Cost about $8.00 for part if you can do it.
