These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. Viewing it in "Mosaic" or "Magazine" will make surf easy.

Can i fix my tv screen is red


Toshiba 36A10 36" TV is the model you have indicated---

If the screen is all red and or too bright (no green or blue can be seen) the problem is in one of two places: Either a shorted picture tube or the board that plugs onto the end of the tube.

That board sends red,green, and blue video and information to the picture tube via 3 pins on the tube (the K or cathode for each).

The set will have either 3 IC's on that board or 3 transistors, or a single larger IC for this.

to troubleshoot this:

I would locate the Red Cathode and unsolder that pin at the socket on that board--takes red out---if you have green and blue picture then---it is either the IC/transistor that feeds that on the board or the tube itself.

If it has 3 chips (usually will each have a metal plate attached for cooling) you can either remove and replace the red one OR what I do is swap it with the green or blue chip---if suddenly you now have a blue or green only screen you know that part is bad--simple as that.

If for any reason the picture tube turns out to be bad--you are finished and so is the set= way too expensive to replace it.

Let me know if you have questions or need advice.

Turn on pic turns red with thin bright red horizontal lines


Sorry to say, but that's usually the sign of a bad picture tube. One of the elements inside the tube shorts and you see the picture you describe, and the set shuts down due to high voltages getting to places it shouldn't. There's no solution except picture tube replacement, and that is uneconomical. You're better off replacing the TV when the tube goes bad.

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.
