Toshiba TP61E80 blows fuse

I just got a toshiba TP61E80 for free a guy said it turned off one day and wouldnt come back on. i opened it up and noticed a fuse was blown. i replaced the fuse with the same one it asks for. and everytime it gets plugged back in it blows the fuse. i tried unplugging everything else from that board and putting a new fuse in and it still happens. nothing looks to be damaged on that board. has anyone had this problem? or is it something that is worth trying to mess with?

    it is the closest fuse to the power cord.

  • brandyn Jan 31, 2008

    im pretty mechanically inclined but not so great when it comes to electrical... would i just check the power cord basically? and where it comes into the board? and across the fuse?

  • brandyn Jan 31, 2008

    would that just mean check the power cord and where it comes in to the board and across the fuse? im pretty mechanically inclined but not so great when it comes to electrical... i have a direct email to if that would be easier to communicate. Brandyn85@comcast.net. thanks for the help.

    i measured between the fuse clip for continuity(sp?) got no reading..im not the best when it comes to using a volt meter. but im pretty sure i did it right. i check alot of the resistors and they showed a reading when i checked both sides. when i checked the fuse clip, i also checked from one side of the fuse clip to one side of where the power cord connects, and there is continuity there as well, and the same thing when touch the other side of the fuse clip and the other power cord prong... is that normal? there is also no fuses in the board at this time...



    if thats too confusing i can try to get a picture of the board online. thanks for the help again. i really want to get this thing fixed.

Blows AC fuse on plug-in is a direct short in power supply...
check components with ohmmeter to find short....Check MOV
across AC line by measuring across AC fuse clip.......T.

    Correct...with no fuse in clip and set unplugged,measure across

    the fuse clip.....if it is shorted,remove soldered in Metal Oxide

    Varistor ..Example = D899 hooked between AC cord and fuse.

    Install new fuse ...try again.....MOV is an overvoltage protect device....................................................T.

  • Vista Electronics Feb 03, 2008

    Please identify all parts by location ....F801 7amp, for example.

    D801,C811,812,813 and then on to the regulator Q801 should all

    be checked......you have a dead short somewhere close ..between the ac fuse and the regulator IC........T.

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.

My Toshiba TheaterView has no sound or picture


You may have overloaded your audio output with the external speakers(impedance or short wire problem?)as a result the audio out i.c maybe damaged which in turn may have blown one of several fuses in the power supply.maybe regular GMA type fuse or picofuses,you can try replacing blown fuse but if they blow right back you`ll need the help of a repairman

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.

No power


I'm having a very similar problem, basically its a fuse that is blowing out, I think the transformer is sending too much power it's way.

Yep, your problem is a relatively easy one to repair if you know how to solder. You better repair it before it blows the fuse though. There are two capacitors in the main power supply that are coming loose and need to be re soldered. There is a Toshiba service bulletin about it. They are marked C809 and C810 on the main power supply board. Good Luck
