BenQ HT2150ST: No power up

[RAMartens]

When plugged in, the power LED blinks red continuously. Temp and Lamp lights are not lit. Nothing happens when power button is pushed. When lamp door is removed, power light is off so safety switch is ok. I find no diagnostic that has blinking red power light but no temp or lamp light lit or blinking.
