[Moved] Help Repairing a circuit board PLEASE

[hamez89]

Hello I have a projector I got it second hand it had a small board soldered to a few points but it was done bad and fell off, I need help identifying a chip that i think may be problematic. I looked for schematics for the main board and even tried to search for a replacement board but was unsuccessful. I called a Authorized repair shop and they never called me back. I've done months of searching with no avail. The projector blinks the different lights green, red, orange.(The lights are Power, Lamp, Temp) Sometimes there solid but never power on. Before this other small board fell off it would turn on but it had recently started to turn off after about 20 minutes like it was over heating. The image would blur as well before it would shutdown.If anyone know where I could locate a part for this please guide me in the right direction. Any options will be greatly appreciated.

The projector is a Sharp DLP XG-F210X, The chip which was solder to was labeled as follows:

AHCT08
BC38406
Un606
36A

AHCT is fast vesrion of the HCT seria. Because it's video the delays could be critical. I would suggest you find exacty the same AHCT seria - you can get them from Farnell with world delivery - world-leading distributor of electronic and maintenance, repair and operations products. | Farnell United Kingdom
