Re: Projector Epson EH-TW570 not Warming Up

any Luck here??, Got the same issue with my Epson EB-S18, when first plug in power button lights blue, when press the power, indicator "status" flashing forever and no boot, No fans spinning and the main board gets a bit hot from the same aria where the mentioned ic in the previews reply from Mr bermo96, and stays blinking with or without lamp.

Re: Projector Epson EH-TW570 not Warming Up

After some inspection, the cap was shorted because the IC was shorted internally. WHen I removed the IC the short was gone. The IC is a SiI9587 Port Processor.

with out the IC304 it should boot and hear the ring sound of boot. you need carefully check after OPEN FB such FB304 / 302

if its cap was shorted then why you removed the IC.. could you remark on the MB photo which cap and IC you removed !!

Re: Projector Epson EH-TW570 not Warming Up

There was a short in the HDMI IC, a cap was shorted to ground. So I removed the IC and the short is gone but still no image and the same blinking LED status. Do you think that with the HDMI IC removed the projector can't work ?

Re: Projector Epson EH-TW570 not Warming Up

then its not boot i think now.. go back to service manual and check the INPUT signal switcher IC. i faced at Benq before and it was no boot i found out HDMI IC was shorted.

The service manual doesn't provide much info but I'll try to find it. Thank you for your help !

No luck with the RST with SW700, it doesn't do anything.
The 3 IC are still getting even with the 3 LCD ribbon cables disconnected. And the LED status has the same behaviour.

Re: Projector Epson EH-TW570 not Warming Up

disconnect all 3 LCD ribbon cable and check if the ics keep warming? and the status led behavior same or changed

BTW you have on MB SW700 for RST

Re: Projector Epson EH-TW570 not Warming Up

So the voltages from the power supply to the ballast are :

4,2 V
17 V
380 V

I unplugged the fans one after another but nothing different happened. I have the same LED status light blinking. I have also the same behaviour when I remove the lamp.

I have notice that 3 IC's are getting really hot when the projector is powered on. They are labelled E06210POA but I can't find any info or datasheet.

Re: Projector Epson EH-TW570 not Warming Up

okay our thought was the boot.. so we have now when you plug it first time at wall socket power LED goes Red as standby. after pressing power the status blinking red and keep blinking..

let trick it by make error.. to see the error section at boot will remark them and give asign or not..such..
1- disconnect main FAN socket and try
2-remove the lamp ( but put back the door )
3- while its on standby.. if you press power on RC it response ? in case yes.. then press freez keep pressing and power it on from the panel switch.. same do it by pressing the menu on RC

Re: Projector Epson EH-TW570 not Warming Up

My bad, the voltages are from the power board and not hte ballast, I'll try to take the voltages from the ballast.

Re: Projector Epson EH-TW570 not Warming Up

be aware of very high voltages ...mine cost me £100 for a new multi-meter .

Re: Projector Epson EH-TW570 not Warming Up

good done.. you listedd only the voltage of ballast socket, how about the socket between PWB and MB ?

Re: Projector Epson EH-TW570 not Warming Up

All the fuses are good ...

[bermo96]

Re: Projector Epson EH-TW570 not Warming Up

Start checking all SMT FB parts specially on the downside close to EX FAN and SCI.. this boards had so many fuses need first to go over them.. then back to boot.

Ok thanks I'll do that.

Re: Projector Epson EH-TW570 not Warming Up

Here some pictures of the main board, but unfortunately there is no micro switches for downloading.

Re: Projector Epson EH-TW570 not Warming Up

would be helpful if you upload very clear photos for the main boards from both sides.

Re: Projector Epson EH-TW570 not Warming Up

in general over projector's there are several Manual Micro switch's do the job of downloading and reading.. i am not sure about the one under your hand if its had such option
