Phillips 64" PTV Issues

It had two blown fuses and a cut power cord when I salvaged it, I soldered on a new power cord, replaced the fuses and the tv ran great for about 8 hours, then shut it's self off. It turned back on and shut it's self off immediately. We took a look at the fuses and they were fine, let it sit for an hour and it worked for another few hours before turning off. Every time it's turned on it turns it's self off sooner, no matter how long it's been turned off or unplugged. It was unplugged over night, ran for 40 minutes and turned its self off, there is no noise or light associated with it's being turned off, but when it comes back on there is an upside down rainbow on the top of the screen. Any help is greatly appretiated.

Re: Phillips 64" PTV Issues

1) Not vertical problem
2) "upside down rainbow" at any time is a convergence issue
3) Replace STK convergence amp IC's

Let me know if you need more help...................T.

No power phillips hdtv projection

Follow cord inside and as seen from rear to the right where cord enters there are at least one and maybe two fuses.

See if the fuses are good or bad.

My tv clicks but never turns on

Model indicated has ONE VERY COMMON ISSUE:

The large power supply board (power cord goes directly to it) develops all kinds of bad solder connections from age.

I have seen and repaired a number of these where removal and resoldering of the entire board cures the issues.

The bad connections can also take out one or more of the fuses on that board--critical fuses that must be replaced with non-generic fuses.

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.

Tv problem

How can this be a generic problem? I had a flashing green light on a Phillips PTV it had a bad solder joint on one of the pins to an optic isolater.

Semiconductor heatsink

they can be very stubborn. If youve taken the heat sinks off the circuit bd so it is in no danger just knock em off of there they can be stuck good. If is the circuit bd your talking about then I guess you realize they are soldered in to the bottom
