Question about Toshiba 61H71 61" Rear Projection Television
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.
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

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.
