Toshiba Sorry I keep bugging you. Do I need to find a special seller for this fuse, or board? Or is it something pretty standard at any Radio Shack? Thanks

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------

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.

House was hit by lightning now there is no picture. The repair man said it is probly a fuse just needs to be replaced. Can I get to it pretty easy myself?


Unplug the set and remove back cover; follow power cord inside---the fuse should be in a holder and if blown will be blackened inside.

Amperage of fuse will be marked on it and on board next to it; DO NOT BUY REPLACEMENT at Radio Shack, get one from a regular parts dealer, the Generic ones RS sells may blow for no reason.

let me know if you have questions.

The fuse rating should be on the metal side of the metal ends of the glass fuse. Very hard to read amps and rating, may need a jewelers lupe. Or take the remains to Radio Shack.

Toshiba 57H81 Flashing Red Power Light, Blown Fused F850+F852


Solved by resoldering some solder joints!!!!!!!
********
Toshiba Model 57H81 Rear Projection TV - Purchased 11-09-2001

Problem: Toshiba 57H81 Flashing Red Power Light, No Picture/Sound, Blown Fuses F850 + F852

Symptoms January, 2009:

  • Upon turning on set I got flashing red power light and nothing else.
  • Removing plug for one minute and plugging in results in:
    • Audible click, steady red power light for 2 seconds then slow flashing red light
    • Pushing power button results in steady red for about 2 seconds then slow flashing red light, no other set activity
  • Removing power cord for several hours and plugging back in made no change
    • Audible click, steady red for about 2 seconds then slow flashing red light
  • Possible related note: Over past several months occasionally the entire screen would flicker momentarily and at other times be problem free for weeks.
  • Fuses F850 and F852 found blown

Repairs Made:
  • PD0074 DEF/CON Power Board
    • There are two main power supply capacitors in this set. They are C-809 and C-810. One their negative lead on the printed circuit board re-soldered leads and nearby contacts. I’m told that because the factory left out a printed circuit board eyelet, the connection will come loose over time. When I called Toshiba customer service they said there was a known solder joint problem causing blinking red light.
    • Replaced blown fuses F850 and F852.
      • I actually installed a fuse panel on the inside of the cabinet and routed the fuse connections here instead of ordering the special fuses and replacing them on the circuit board.
      • Had to use a 5 Amp SLO-BLOW for F850. Fast blow does not survive power up. Get the red blinking light.
      • Used a fast blow 2 Amp for F852.
  • PD0073 SIGNAL Board
    • Re-soldered Q751 + Q752 STK392-110 Convergence Amps
    • Re-soldered adjacent pads that looks suspicious

Total Cost to Repair about $10
  • Twelve hours of my time over three days to research issue, disassemble set, make repairs, add fuse panel.
  • Already owned Service Manual and Circuit diagrams from a different 2004 repair.
  • Less than ten dollars at Radio Shack for fuses and fuse panel. Already had wires, etc.
  • Some solder. Already owned de-soldering tools, etc.
  • Visited both local authorized Toshiba factory service repair facilities. One said repair would have to include replacing Q751 + Q752 STK392-110 Convergence Amps with ST392-180, and realigning set for a total of $500+ and it would be more if they had to order a power board. NO THANK YOU! Other shop said $65 for site visit and $30 to make an estimate that could be applied to repair.

Hi, The problem lies within the unit. You have a hardware failure within the board. Most likely the power supply board needs to be repaired or replaced. I hate to give you this bad news, but the cost to have the power supply board repair or replace will exceed the value of your rear projection television. Of course it all depends how much you want to invest in the television. Sorry, but I wish I had good news for you. Just being honest. Thanks, Mike

Pioneer sd-533hd5 not turn on


Theres 3 boards on the bottom inside of tv. The middle circuit board has 3 small fuses toward the center of the board. Just pop those fuses out and look for the 1 that is broken or burnt. Taken the bad fuse to radio shack and get replacement. Very easy repair.
