SOURCE: power surge

Yes possibile there's some IC's that are burn inside it and also the power supply can be damage so resetting it will not do anything , if you can take it to a repair center and let them check this unit and fix it.

Good luck........

Since this is a DLP type set, there is a lamp and ballast involved. When the set shuts down, are there any indicator lights on the front? If so, check the owner's manual for an explanation of their meaning. Typically, the lamp can cause this or the ballast. If either of those are the problem, usually the lights on the front panel will indicate it.

Keep us posted.

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.

How do I turn it on manually/


if the remote/TV button isn't turning on the set you have a problem. You maybe to force the set on manually by installing a jumper from 5vdc standby terminal to "ps on" or "on" terminal on the power supply. I woouldn't recommend this unless you are technically inclined. Sounds like you either have a failure on the power supply board or main board.

Toshiba 32HLX95. Worked perfect till I unpluged it. Know when you plug it in and turn it on you only hear a slight clicking noise but no picture and the red power light does not come on.


Most likelly it's your power supply. the clicking sound is the the power supply trying to turn on. You can check the capacitors sometimes you can see a few bad ones and replace them and that solves the problem. If that does not work you can replace it.


You can get parts at www.interliquidparts.com

I have a toshiba tv model 32hlx95. the power suddenly doesn't work. can't turn the tv on.


Hi ,

Here are some DIY steps that may help you fixing the problem.

I'm assuming that your unit is dead set without an standby LED light and your outlet is live.1.Power cord - check the cord it might be opened (no continuity).This is due to frequent bending,pulling. 2. Power switch - check for dry joints, open contact. 3.Check the internal fuse- sometimes the fuse fail because of the power surge, replacing with new one will cure the problem, If this is the case I've advice you to use surge protector/AVR (Automatic Voltage Regulator). However if the fuse blew again this is an indication that you have a shorted parts on the power supply, you may visit the link http://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info. If no reaction and still the unit didn't power up then you have an open parts on the power supply.

4.If you see that the fuse is intact on the board, don't attempt to touch anything because there somefatal components stored electricity enough to hurt you with a simple mistake only.

The next steps should be done by an expert or qualified technician because isolating the problem on the power supply is quite technical.

Also check if your unit is under warranty before opening the back panel, it will void the warranty. Avail it because the manufacturer of your unit will fix it for free or a little charge only.

Hope it may help you.
Thanks for using fixya.

Toshiba 50H81 Has Power but No picture or Audio


ok i'm goin to need more info about your problem. you stated fuses and didn't say the location numbers of the fuses. Also, have you rechecked your fuses to see if they are all still good? 3 fuses sounds like more then one problem. once you tell us your loc#'s of your fuses, we can look into your problems.

Check fuses on Power Supply board (F850, F851, F852) and all other fuses. Replace blown fuses (will need an ohm meter to check fuses). I would also replace the two convergence amps (STK392-110's on the signal board, the big black ICs on the two heat sinks). This worked for me.

No power blinking power light


You would need to check the power supply and shutdown circuit for a faulty component. There is a manual called Toshiba power spply and shutdown circuitry available for 10.99 at the following link, That manual covers your model as well as quite a few other toshiba models. It gives step by step instructions on what to check, And the site offers ree unlimited support to help you with your diagnosing. They will een email the manual to you instantly if you returnto the site and click thecontact us link requesting that they email it instead of mail it. Here is the link just click on the Toshiba section and go through the pages of listings you will find it listed there.
