We have an issue with blanking out. We have the above TV and have cable with DVR. While watching TV, the screen blanks out for a second and comes back. It doesn't happen when we watch dvds. We assumed it was the cable company and for the past 4 months they have tried numerous things. They are now saying it is most likely our TV. We bought it in November 2005 and have no warranty on it. One would think it would show up even with movies if it was the TV, but it doesn't. Even with our DVR, if we are watching at the same time it is recording, we can see that it blanks out, yet when we go back to watch the same recorded show, the blank out is not there.
We have not seen a pattern yet on when it happens. For example, if the tv is on for an hour does it start happening. It can be right away and other times longer before it starts blanking out. Sometimes the blanking out can happen alot during a show, and other times, it can be spread out more.
OUr next step is the Toshiba Repair Center, but they want alot of money just to bring in.
In looking online with Toshiba, they talk about a lamp you can send in for, but we don't know if this is a lamp issue. Again, you would think it would happen with DVDs too.
Any thoughts are appreciated. thanks

Re: Toshiba DLP 46HM95 - blanking out issue
I am assuming that when the set blanks out, you don't notice the power light flashing any certain sequence. What I would try if that is the case, would be to press a button on the remote control to bring up a menu on screen when it blanks out. If you can bring up any writing on screen while the picture is blanked out you know the Lamp is doing its job. Also, do you lose audio when this happens? If so, it could be a problem in the power supply or if you have the cable connected directly into the TV's tuner stub, the problem might lie in the Tuner. If you have On Screen Display when this happens and audio, then it looks like there is a problem in the video circuits of the TV. If you have a cable box hooked into the TV, the problem could be there also. Now you know why the Toshiba Repair Center gets the big bucks to figure out these things.

More than likely, as with almost EVERY 46HM95, it's your light engine or color wheel (same thing) starting to go out. The piece alone will run between $500 and $750.. Install prices depend on where ya go. And don't let the Toshiba rep lie to ya. That person might not have known the problem, but Toshiba as a whole has heard about this problem and known about it. If you've searched the internet for the same problem, you'll see that almost everyone that has bought this TV gets the same response from Toshiba "Never heard of it" or "it's out of warranty, tough luck" I'm surprised there hasn't been a class action lawsuit yet.
Your bulb may be blowing because of airflow issues or power cycling issues, first does your outlet get switched off at any point in time? if so you may be killing the bulb before it cools, if you turn the set on/off alot and or restart it after off quickly this could lead to permature bulb failure, if the original lamp was not replaced with a proper lamp to match the ballast it could blow the bulb. If your tv is too near a heat vent or the airflow thru the set is not adequate it could blow the bulb.
