    STR-DE345 5.1... Problem
    is valid for all Receivers


    check to see if you put the correct fuse in the receiver, and if it is the correct one, you will need to check the protection circuit because with it being turned up so loud the amp was probably damaged. in most cases with protection circuits you will probably find your problem with an output transister. than check for blown caps.
    ---------------------------------------------------------------------------------------------
    sorry but I'm a little illiterate when it comes to technical terms... So what am I looking for? where is the protection circuit? how do I know if something is wrong with it? same with the output transister and the caps? Thanks !! : )

Had a blown fuse on main board 125V 4A replaced and indicator came on green light flahes twice and goes off


Something else went when the fuse blew---voltage checks are needed and someone needs to check for shorts on the set to ground.

It keeps blowing the 4A-125V fuse every time I plug it in...


There is something shorted in the system. often it is the audio output which fails especially if it is run at high volume levels. Unless you are trained in electronics, I suggest you find a repair shop that repairs audio equipment. (Sorry) Hope this helps

I plugged it into 220V outlet and Brother HL 2140 only accepted 110-120V. Is there a fuse somewhere I can access and replace? THank you.


hi. I had the same problem and to fix it you need to take printers right-side cover off. Underneath you'll find a Power Supply Board - hidden under metal cover. Take it out and disconnect two cables from it. Now, I had to replace an fuse 125V 4A and varistor E241AD 83P on the Power Supply Board in mine HL-2140. It works fine now.

Note: I could not find the exact replacements in electronic store so I used:

- fuse: 250V 4A

- varistor: FNR 10K241 (241 is the important number)


Hope it helps.

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.

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR LEAKY C9A60 470 PF 1000 V PART # 154P400030, PARALLEL TO D9A57 ON THE POWER PCB. 2. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR OPEN FUSES F9A04 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT
