Question about Toshiba 50HM67 50" HDTV
I unplugged my tv while it was on and when i plugged in back in the lamp light started flashing. It has done this before but turned back on in 5 or 10 min and now it will not. i got a hold of a new lamp and it does the same thing. so its not the lamp. any ideas would be great.

I think your problem is actually simple enough, but may require proffessional service, depending on your fundamental skills with electronics. It sounds most likely that your power supply is bad. This would explain why this happens at the begginning and not later on. You see, once the transisters are warmed up, it is not so demanding on thepower supply. You may want to have it proffessionaly done, which may cost about 300-400 dollars. This is a good tv set, so it may be worth it to you, but I would suggest you look around at replacement costs and determine if you want to gamble with it. Good luck.

SOURCE: Replace Light Engine
I have the 62HM95 and my light engine went out between 2 and 3 years. I will never buy a Toshiba again. I have had nothing but trouble with the components and the customer support. I am in a class action lawsuit with them, but I doubt very much will come of it.
As far as fixing your TV I was in the same delimma as you. I wasn't willing to pay nearly $1000 to get this set repaired when it already cost $3000 and it started having problems within the year and major issues after 2-3 years. I was willing to risk a couple hundred bucks that I could fix it myself. If you aren't very handy with taking things apart and putting them back together, by all means don't do this. It is pretty easy to do and you can figure it out as you go, but I wouldn't suggest you doing this if you weren't willing to take the risk of really messing it up.
I didn't go to Part Store.com because they wanted $456 and then when I finally decided to do it they raised the price to $556...No way, I found http://www.tristatemodule.com/html/light_engines.html and you can get a light engine that is refurbished for $250, or you can have your light engine refurbished for $200, which is what I plan to do if this one fails in the next two years. I looked at their site and it doesn't show that they have any in stock, but they may if you call. I wasn't comfortable sending mine off to be refurbished because I wasn't sure if I would remember how to put it back together, and I'm glad I didn't because the one they sent me didn't work, which sucks, but it happens. I called them back and sent it back to them and it worked fine. All in all, I had no instructions or any other help besides my memory of how I disassembled it and it only took me an hour at the most, not really too hard.
The only other issue I had with them and it really wasn't with them as much as Toshiba is, I received a light engine for a 46" model, which when I talked to Toshiba they swore up and down that it wouldn't work, when I talked to TriState about it they said that Toshiba would say that and they had used it in 1,000's of 62" models and it's worked fine. After they replaced the broken one they sent originally, the new one worked fine and is still working brilliantly and I have my original 62" light engine to get refurbished if anything should happen again. Their shipping time was good and when I returned the product to them, I received a working part pretty quickly.
For $250, this would be the only way I would go. If this hadn't worked, I probably would have just went out and got a different TV. I hope this helps.

Likely to be the STK convergence chips causing a protection circuit to switch the TV off. Have you got any onscreen convergence problems (i.e, colour fringes)?
