Question about Toshiba 61H71 61" Rear Projection Television

3 Answers

No Audio or Video

About a week ago the edges of the television screen were flickering but would go away after about 10 minutes or so. My family told me that it started flashing orange then the Screen went black and no sound. I found that the power indicator on the front was flashing, but could not shut off the TV or turn it on; just a black screen with no sound. I shut power completely off to the unit and waited a few minutes then restored power and the TV came on and worked fine. Today when I got home my family said that when they tried to turn it on today it just went black and no sound. I tried to shut power off and on but no luck. I hear a relay click when I return power but nothing appears on the screen and no audio. The power indicator is flashing.

    I plugged the TV back in after about a half hour and it came back to life, but kept flickering on the edges and then it acted like it was going to shut off again by flashing off then on every few minutes. I jumpered the failsafe x and r and it shut off and acted just like it was before. Could my fail safe be shorting? It reset after removing power. I see no bulging caps. Whick transistors should be checked?

    I hear a hissing noise coming from the transformer T862 area; don't know whether it is coming from it or something else around there.

  • ricke Sep 02, 2007

    Could this be connected to the convergence some how? While the television is on alot of things on the screen are warped and distorted and I see red outlines on things on the screen. A few months ago I also had another problem where the screen was distorted. I tried the standard convergence and that did not work so I went into the service screen and did some adjustments. It seemed to help at that time; but this problem seems more extreme where the whole tv goes out.

    The television flashes. I hear a hissing sound coming from around the Voltage regulator area. What would hiss? There is the transformer T862 in that vicinity.

    I pulled out the board and looked at the 2 caps:C809 and C810 the solder joints are good also I checked out the fuse F860 and it is good also.
    Not long ago I had a convergence problem where I went into the service menu and ajusted the red, blue and green. Everything looked fine but when I pressed the touch focus button it came back with an error. If my two convergence chips STK392-110 were going bad could that be causing this problem?

    PS: I do know how to solder and have a meter but I do not have and O-scope.

  • ricke Sep 11, 2007

    I replaced my two convergence IC's and resoldered the Caps.
    I am still having the same problem.
    Previously I went into the Service menu and accessed the self diagnostics. It came back good except for main and sub were both red. After I did the work to it main is now green and sub is still red. What does that mean?

  • ricke Sep 12, 2007

    Yes

  • ricke Sep 12, 2007

    The service manual does not say what the red sub means however.

This is a very common problem with this model and a few others that was manufactured the same year of this model of Toshiba TV set. The service bulletin number is TV0201. What you need to do is first unplug the TV set. Look around the power supply area for a blown fuse, a round glass cylinder shaped device. The number on the printed circuit board should be marked F860. If this is blown, do not replace it yet as you will cause more damage if you do not repair the original problem. You need to find two larger type capacitors around in the power supply circuit marked C809 and C810 on the printed circuit board. These capacitors come loose over time and the connections go bad. You need to simply resolder these two capacitors really well and then replace the fuse and you should be all set. If you have no experience soldering on a printed circuit board, give this information to a repair tech and they should not charge you a lot for this repair. Good Luck

    Do you have the service manual on this set?

  • Larry  Dillon
    Larry Dillon Sep 12, 2007

    Have you reset the trouble codes in this set yet. A factory reset? It should tell you in the service manual how to do this. if you like, send me a copy of this service manual to techman32k@yahoo.com

Sounds like a power supply issue. It's producing the lower voltage needed for the lights, but not enough for the screen or sound. You can get a list of parts for your model here: http://tigerdirect.partsearch.com/GetModel.aspx?MfgName=Toshiba&BrandName=Toshiba&ModelNumber=61H71&page=9 I suggest you open up the back and look for bulging capacitors, or possibly power transistors that may be bad. You can order replacements at the above link, if you find any damaged. They'll have to be soldered in place. Unfortunately, you can't order a whole new power supply for this one. If you don't feel up for a soldering job (once we find where the fault is), you'll need to take it in for service.

When it flickers, can you still see the text when the screen goes dark?
May have to use a bright flashlight set right on the display to see
the text on the screen beside where the light sits.
That will tell you if it's the backlight.

You can also look at a grazing angle into one of the edges to see if the
backlight is flickering when the display does.
When it's cold, does it start with a slight pinkish color? That can be
a sign of backlight going bad.
Anything interesting happen when you flex the cable by moving the screen?

I'm not saying it's impossible, but I've never seen software cause
consistent screen flicker. And if the vga port doesn't flicker, sw is
even less likely the problem.

If you bet the odds, you'd bet on a bad display cable.
Won't hurt to try replugging it.

If that doesn't help, then your monitor may be dying....

The flickering is most likely due to a faulty fluorescent backlight. Once the bulb heats up the flickering usually goes away. Some bulbs are easier to replace than others so I would contact your local TV repair shop.

Blank screen when tv has been on for 10-20 minutes


Hi jilanfa00, 
I am happy to help, we need to check the backlight inverter.
  1. Turn tv on and get to a point that you have audio.
  2. Take a flashlight and shine it on the screen.
  3. Look very closely at the screen for a very dark video image.
If you see an image you have a bad inverter, you should be able to replace it yourself. I can walk you through in chat. Let me know your findings. Lone99star
