I have a 55" Toshiba Rear Projection TV and it works great for 30 minutes or so and then it just turns off. The picture is prefect as is the color...Then will not turn back on again, just flashes a red...

As your instincts have told you this MR.Techie is trying to rip you off. I think what you have is a faulty ballast. A ballast is a part in the projection tv that supplies power to the lamp. If the lamp is drawing more power than normal, then the ballast turns off and resets itself after a while. That's why the set works for a while before turning itself off again. A faulty ballast may reset even though the the lamp assembly is drawing normal power. You may also need to replace the lamp if it doesn't resolve the issue.It is a relatively inexpensive part but you will need the techie's assistance to replace it. Should cost you around 100-150$ for the repair.

Feel free to post back if you need more info.
