#1 Acer H6510BD Projector - Wont turn on / Keeps crashing

by Spenbarkley • 24 June 2024, 16:05
So I got this Projector because some company wanted to throw it away as it just won't turn on when pressing the power button.

Here are my observations:
    - The red power LED is always on and (only sometimes) the red LEDs for lamp and temp also light up.
    - When the lamp and temp LEDs light up, they don't light up consistently and seem to flicker at a high rate (around 50Hz).
    - The flickering makes the LEDs appear dimmer than expected.
    - The projector has suddenly worked at some point, but it kept crashing when I tried watching a movie on it.
    - I was able to figure out that the lamp was in use for about 5 hours from the menu.
    - Now it's back to the power LED on but no response.
    - Whenever it crashed, it was immediate, meaning the whole thing was instantly without power. I didn't touch it when that happened.
    - Visibly, there is no damage on the PCBs or any other part.

I'm a beginner, so it would be nice to know where to start measuring/looking. I accidentally touched a big transistor while trying to measure some voltage, which wasn't a pleasure. :?
So before I hurt myself further, I thought I'd ask for help.
