I had the sample problem. The fuses are in the middle of the board. You need to disconnect all wires carefully so you can put it back. Find the blown fuses and go to Radio Shack and buy replacement fuses with the same ampere . The main cause is the two STK divergent chips mounted on the biggest heatsink. You need to unsolder them CAREFULLY and buy new chips STK 110 or STK 180. I recommend STK180 because it can handle more heat. Search the web for STK 110 or STK180 I will cost about from $20 to $50. After I replace the 2 chips STK180, I never have any problem since. THe performance and the sharpness is much better. Try to buy brand name SANYO etc..
don't buy bargain chip, keep replacing chips you are going to damage the board. Do the job once and enjoy....

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.

If you have any questions or need advice reply to this posting here.

22 is a error code for a short protect which is triggering shutdown . Try unplugging the crt circuit boards and seeing if the fuses still blow when you press power.
