Question about Toshiba TN61X81 61" Rear Projection Television

1 Answer

Toshiba TN61X81 took power hit

Some time ago we suffered a severe power surge at our home.  According to a friend whose knowledge-base I trust, this "type" of surge sounded like a current-reversal, which according to him, even my $300 surge surpressor protecting all my electronics, is not designed to trap.
The problem:  Even though I lost nearly everything (DVD, VCR, Amps, telephones, etc.) the Toshiba still powers up, has sound, can still change channels, and even still displays the onboard menus (Volume Up/Down bar, channel display, etc.)  What's missing is the picture.  Have tried all the various input...coax, RGB, S-video on the front.  Nothing produces an image.
Would like to know if, based upon this description, does this sound like something I might be able to DIY?  We live rurally & getting a repair company out here is going to cost a small fortune.
Thanks in advance for your time.

You will need to trouble shoot the various power supplies most likely something minor in either the stand by or start up circuits. I recommend that you get a service manual at the following link as they will email it to you and also help you diagnose it with free tech support. Here is the link.

SOURCE: Problems after convergance IC fix

try not to mix areas in the tv chasing several problems.

  1. Lets get back: i hope the tv was doing fine before to start digging into it ( was it?) Was the tv complete tested before to make sure the buttons were working all and the audio was there. I mean each part of your tv has different solutions:
Think you have an animal with several heads now:
  • the buttons in the panel (some working is good! some others can be replace and there it go all panel works)
  • audio mute (maybe no signal and automatic mute is there. or maybe really audio is damaged. Leave it at the end is another area.
  • Touch focus is the the program controlling convergence digitally talking. If the tv is not yet fix with the amplifiers then the problem still landed in another area not in the digital control.
Finally Start over! Get into de convergence and get your three tubes at least close to convergence (forget auto focus now) three screens together or almost but three rectangules with white noise. No having GUI you mean OSD (i gess) (on screen display) channels appearing when you push that button or audio level line or menu letters (several buttons have to be touch to make sure of there is not OSD.

if the tv has not white noise the screens are without convergence. you are digging in a set with maybe 5 problems the three you told me plus the other posibilities im gessing and i hope you don't have. So slow down with the repair and try step by step. bye now.

Why won't it power up?


Flat Panels are quite sensitive to power surge so if you didn't have it with a protector, it's quite probable that some of your TV's circuits suffered a "burnout".
If you don't have the technical knowledge to repair a TV, your only option is to take it to a repair service.
For future prevention, see some surge protectors at Amazon:

Tv does not turn on after a thunderstorm and several attempts at power returning to the home. The power went on briefly then shut off several times, now the television will not turn on. We had the tv...


Check the main fuse in the power supply, the TV also has small surge protection devices (MOVs) installed after the fuse, any surges the come along and big enough will cause the main AC fuse to blow. When you surge protector, EVERY connections must go through the surge protector, for example, the AC cord of the TV is connected to the surge protector, the cable connection did not go through the surge protection, the surge then can get to the TV through the cables.

If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

My toshiba r10 laptop wont turn on the green power light to the front is on but the yellow battery light only comes onn when i plug in the power cord to it and it only stays about 2 seconds


Ok here's what you will do

1) Unplug the notebook from the ac adapter (charger power cord)

2) Take off the battery pack on the notebook

3) Once the ac adapter and battery is off the notebook, hold down the power button for 15 seconds

4) After 15 seconds, let go of the power button

5) Now plug in the AC ADAPTER (OR CHARGER POWER CORD) ONLY (DO NOT PUT BACK THE BATTERY PACK)

6) Now press the power button once.

7) If the unit boots, the unit suffered a slight surge

8) If the unit does not boot and remains dead, the unit suffered a severe surge and may be burned out and needs replacing

I hope this helps and let me know how it goes afterwards

How do i fix this


I just posted this in a previous message:
"In both cases, I think you are either suffering from a failed power supply or the supply is cycling because of a 'downstream' problem that could be in the high voltage circuit. In each case, the blink count probably would tell you approximately where the problem is located but only a Sony tech will have access to the codes. After all, we are only mortals.  "
