Power comes on try's to eject disc power light turs yellow then goes back to red light. whats wrong any info

Hi, alot of people think they know the answer to things they know nothing about.....2 units getting the ylod does not mean someone should trust you more...lol
I own a console repair shop and have fixed over 150 PS3 units. your unit displaying the flashing red light is telling your there has been a malfunction.
some people turn their systems back on to realize they have the ylod and the unit quickly turns on then off displaying the green and red lights at the same time,
giving us our yellow light. I have come across a few consoles with the exact problem you refer too. Your system is shutting down due to a blu-ray drive failure(most likely a problem with the pcb on the bluray drive.) I was able to fix the issue by replacing the pcb, the trick is finding a compatible pcb. you have to match up the revisions.
Parts may be hard to come across, these pcb boards are very rarely listed online. So my suggestion to you, is to find a console repair shop around your area, and see if they may have the part you need, otherwise sell your unit for parts. With blu-ray lasers being expensive, you can still easily get 80-100 for the unit.

good luck,
