The Symptom:

When I connect the power cable, the small LED indicator on the front lights up. However, the projector does not actually turn on. When I press the power button on the remote, the LED blinks/flashes in response, but the fan doesn't spin up and there is no light output from the lens.

What I've tried so far:

• Checked the power cable and adapter (using the original Samsung 65W USB-C brick).

• Tried a different wall outlet.

• Attempted to power it on using the button on the unit itself, but it still won't boot.

Is this a known mainboard failure, or could it be a software hang that requires a specific hard reset sequence? Any advice on which internal components I should check or test with a multimeter would be greatly appreciated.

Thanks in advance!

Projectiondesign F35 AS3D Vizsim 1080

When attempting to do a firmware update it comes up with the message detected firmware and a few seconds, prompts to remove the USB after reading its contents reboots after that, but nothing is installed.

Current firmware is 010-0003-09

Trying to update to 010-0003-25 downloaded from Barco website.

Have followed instructions in manual on Barco website.

Memory stick has USB FAT-file system and the unzipped release.tar on the root of the USB memory stick.

Have downloaded the firmware twice and tried two different USB memory sticks.

Am I missing a step not mentioned in the manual?

Are there any stupid things I might be doing wrong without releasing it?

Thanks.

There seems to be a yellowish stain in the middle of the projector. Pls do let me know how to fix that.

I’m in the process of fixing my Epson EB-W130 projector.

The projector doesn’t turn on or show any indication of powering up (power buttons do nothing and no LEDs light up when power is applied).

I’ve been trying to locate the service manual for it. (Note this is different to the user manual).

So far google searches have only returned the user manual.

Does someone know where I can find it? Or perhaps point me in the right direction to obtain it please?

Cheers,

Currently my investigations point to the main power supply (main PSU).

I’ve found:

• 2 fuses - all intact still.
• 1 thermal fuse - which is operating correctly.
• 240V AC (Australian mains) is measured on the main PSU board successfully.
• Probing the main PSU shows that it’s output to the processor PCB is 0V DC (expecting 17V DC according to the silkscreen on the main PSU board). I’ve even hooked up the oscilloscope to see what the main PSU does when power is applied. Nothing, there’s a small flinch in the voltage level but nothing to really indicate that the power supply powered up and had it’s output disabled by the processor board. There’s not even any activity on the optocouplers that pass control signals from the processor board to the primary side of the main PSU.
• Disconnected the main PSU from the processor board. I read 10 V DC on the output (expecting 17V DC according to the silkscreen). The oscilloscope shows a very clean 10 V DC signal.
• I try connecting the power supply to the processor board again, this time with the optocoupler signals disconnected to make sure there’s no ‘kill’ signal being sent to the main PSU. Power on, and the supply’s output measures in at 0 VDC again.

Perhaps the main PSU is not working properly (indicated by 10VDC being measured instead of 17VDC). It could therefore be struggling to source enough power for the processor board to boot up?

I’ve started reverse engineering the power supply a little to double check that the PSU IC, transistors and other components are working/biased correctly. (This is where I was hoping for a service manual to help me along). Nonetheless I will continue investigating.

At this stage I’m not sure if I can trust the 17V DC marked on the main PSU’s silkscreen. I have thought of powering the processor board using my bench PSU - I just don’t want to risk damaging the processor board until I’ve investigated the input range it can handle. I see switching regulators, so perhaps it has some tolerance to input voltage. My thought is - if it powers up from the bench supply and provides some activity on the status LED’s then that’ll add evidence to the problem existing at the main PSU.
