BenQ th585 schematics or service manual

[Paba]

Hi there.
Looking for schematics or service manual for BenQ th585 projector. Can't find it anywhere.
My friend tried to clean it and knocked off quite few components of the board. Hdmi area is affected so no signal from both hdmi but VGA works fine.I saw some photos of boards from AliExpress but there is no way to know what values them components are. Can send some photos if required. Thanks for help

what kind of cleaning to have many parts fly out from boards..
notice the circuit at Benq had many parts missing by original depend on the version of boards...
HDMI switch on at this Brand depend on the strong signal db and the first version of HDMI cable. any one are not not matching it will failed to sync the signal.

Well it looks like he used some sharp edge to open it. I compared board to same boards for sale. And in "missing" spots solder had remains of previous components.

Hi thanks for reply I'll be home tomorrow as soon as I get to my workshop I will proceed with your hints thank you so much. I think I haven't got any tv boards. I do have Xbox one S and Ps4/ps5 boards if that helps.
