Replacement of the board is never recommended, unless the board caught fire and is all burned up. If the convergence circuits quit working then you still see a picture, but the 3 colors just dont line up with each other. The picture shutting off, closing in and then popping back to full suggests a loose solder joint in the horizontal deflection circuits. This is something that cannot be adjusted in the service mode and the repair should be handled by a qualified tech.

SOURCE: 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.

SOURCE: I have a toshiba tz50v51 projection tv. the red power light is on

It could either be due to the convergence Circuits ( If the Power Indicator Blinks) or the power deflection board if it doesnt blink. I have a source for parts if you would like the link.

SOURCE: no picture and the power light blinks

A red blinking light could mean that the lamp timer is at it's limit and it is time to change the lamp. You will also have to reset the lamp timer by pushing and holding down 2-3 buttons on the tv or remote. Refer to your user guide for the proper way to reset and or change your lamp.

I have Philips Flat Tv model # 42pf7320a/37 ..I have a clear picture but no audio, just white noise and static.


Clear picture but white noise and static?!!!!!. What do you say?. Check whether the audio is muted by accidental press at remote control button. Enter its sound menu, and check it. If muted, as you know there will be no audio output. If not muted, check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. Surf the site with patience.

It will be best to replace the power supply regulator board as card basis.
Fuses can be bought from most of the electronic spare part shops. But, before replacing the fuse, you should check out the cause for the blown off the present fuse, and should rectify it; otherwise, replacing a new fuse at this condition might make problem more complicated.

LG PDP42X3 No Picture - I have sound and blue power button in front but no picture. How do I tell if the ceramic fuse is blown? They are all still pure white. If they are not blown, does that help with...


This condition, sound no picture, is generally a result from a failed y-sustain and/or x-sustain board. You can check the fuse for continuity or resistance using a multimeter. I am helping someone repair their LG 42pc3d, that's why I thought I'd help you out too.
