    The actual Model# for my set is 51H83. I got a service manual for it but it doesn't cover lamp removal or replacement. I appreciated the answer that was given, but wanted to be sure if the answer was correct for my model. I do think it is the lamp and will pursue that course. Any additional info would be greatly benefitial.

If the light is on a steady red, thats an indication that the lamp is bad, or the lamp circuit is bad. If you replace the lamp, and the set still does not come on, this is going to be a tough one if you are trying to trouble shoot it without a manual. You can get a manual here http://www.servicemanuals.net/results.aspx?type=SM&brand=0&model=62HM94e Start with the power supply, and see if the regulator is working. If so move on to the lamp ballast circuit. If you need an owners manual, you can get one from here http://www.tacp.toshiba.com/tacpassets-images/models/62HM94/docs/62HM94_om_e_rev1.pdf Good Luck

    If you replaced the lamp and the set still does not work, return the lamp and get a replacement. If that lamp does not work, then you know you will have to search in another direction. Good Luck.

    The service manual does not cover the lamp replacement but the owners manual does. You can download that for free from Toshiba athttp://www.tacp.toshiba.com/tacpassets-i...
    It is in chapter 11 on pages 98 through 100.

    OH man, I know now why you cannot find the lamp for this TV set. I just realized your model still uses picture tubes. You have to be careful when you post the model number. I just saw your real model number, the 51H83. There IS no lamp inside this TV set. Three picture tubes yes. Now on this TV set, the reason you have no picture is the set lost the vertical sweep and the set automatically shuts off the voltages to the picture tubes to protect the lamps. I have seen the vertical output IC cause this problem, I have seen the Capacitor in the sweep power supply that feeds the voltage to the vertical out put IC, and I have also seen the convergence IC cause this problem. The set you first mentioned is a DLP set, you do not have a DLP set. You have convergence adjustments and a magic focus to adjust the convergence on the TV set. A set that uses a lamp does not have convergence alignments my friend. I am glad I cleared this up.

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.

Toshiba MD20FP3 Combo does not turn on. Help!
Not unless you have taken the time to learn all the safety issues concerning the HI voltage safety facts, in the repair of electronics? It sounds like your tv has a problem in the sweep/power supply circuits, and since these sets have NO user serviceable parts< its best too leave these types of repairs to a certified electronic technician. Good Luck
