Those 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 section 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.

If blinks continue without any pause, or the LED light stationery; the main board is faulty./

Blinking codes details of many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

Is the red flashing light on evaporator circuit board normal.


some units just shine steady others steady blink as normal,,the trick is does it blink a number of times then pause this indicates a code. some will display multiple codes at one time, generally there is a sticker on the access panel inside or out with a listing of codes. thank you and hope this answers your question, most units have safety proticalls to prevent the unit from working under dangerous conditions

My 52" Mitsubitshi Diamond series will not turn on. It has a blinking green light that says timer underneath and the system reset button had not effect either. The TV is only six years old and rarely...


Probably a blown pico fuse on the circuit board, convergence amplifier issue, or blown HOT transistor. Could also be a solder connection on the pc board other bad component. Count the blinks and note any pauses in blinking. This could be a trouble code. Type into google your tv and model number and the words "troublecode ## " if you had one or "steady blinking green light" if it just continuously blinks wit no pauses. See where that takes you... Hope that helps some.

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.

It's not coming on probably because the safety sees a short and is sparing you smoke damage. Double check to make sure any solder didn't cross or drop to another set of solder joints on the bottom. You might be able to get a service manual from here that could tell you more about the lights -> https://www.manualsparadise.com/ShowProductsForModel.do?model=M22931911
