Lamp went bad so i replaced it.the picture is like new really looks good.2 weeks later the tv will not stay on for more than 10 mins.turn it back on stays on rest of the it will not stay on for...

First You have to check the lamp cooling fan. if the fan didn't run at the correct RPM then the lamp will not get proper cooling and the lamp will get over heated. This will result in termal shutdown. And the tv will go to standby to prevent from burning the lamp. Just replace the fan. If the problem remains after replacing the fan then the problem is wiih lamp blasting circuit. If so you have to replase the lamp blast.

My 50 inch magnavox takes ten to twelve trys to get it to stay on it repeatedly shuts off on its own and the red lights come on


It's the problem of overheating in the power supply board of the TV.on the power supply board of the TV there are few capacitors and IC.any of this ic is got short or may be due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.
Take care in solving the problem.....

Turns on and off green LED flashes until TV turns back on.

this is a symptom of a bad lamp. for some reason it won't spit out a lamp error. shaking up the lamp will sometimes fix temporarily but you will find replacing to be the answer. if your tv has a fan error, you will get 4 red blinks.

Toshiba 46h84 rear projection shutting down

I have a Toshiba 46h84 with similar problem that needs a new green crt. Mine does not have a cooling fan. I don't know if having a cooling fan would help the problem, but mine didn't come with one. There are rear projection TV's that have bulbs in them that require a fan. This particular model uses a red, a green, and a blue crt to generate the picture and probably doesn't need one.

Many problems can cause this symptom. The only thing I can suggest is check the cooling fans. If they stop or are running slow because of dust they can trigger the shutdown.
