Question about InFocus ScreenPlay 5700 Multimedia Projector

Unit will not Power Up.

While pluged in the power LED continuously blinks to the beat of the fan on the lamp. The lamp fan is continuously running while unit is plugged in and it has a ticking sound which the power LED blinks to the beat of the ticking sound. I push the power button and nothing happens. I'm thinking either the lamp is bad, or the power supply is bad. Any ideas? Similar problem - the power light blinks very rapidly a green color. I got a new bulb and did not help. Infocus says it is the power supply and wants $550 (heck, I'll just get a new projector). Took it to a local shop and they did not know what to do. I'm now shopping for another power supply to try and repair myself. Anyone done this, and know where to get the power supply?

Terry, I had the same problem. Its a small capacitor on the power board labelled 'C16'(right in the middle of the board) its value is 16volt 100uf.
I also changed the biggest one on the board as well( 450volt 270uf @85deg). The big one was sourced through RS components @£5.14, the other I got through a maplins store for the grand sum of 13 pence.
Both are quite easy to change if your not adverse to taking the unit apart. (Just remember where all the leads plug in).
A torx T10 screwdriver, and soldering iron is all you need.

It's more like the eca controller (main board), in which case it is cheaper to get a new projector. besides, infocus doesn't have any power supplies or ecas in stock.

1,Check the fans ,whether each fan is running,when you turn on the projector
2,if the fans run, then ,check the lamp or lamp ballast

turn on the projector ,at the same time ,if you can hear a continuous beep beep sound (the ballast igniting the lamp)

Power led and lamp led blink simultaneously on my jvc hd65s998 rear projection tv


You might need to replace your lamp driver, or ballast as some call it. This is what strikes the lamp to make it light.

Infocus screenplay 7200 fan failure with new lamp After powering on, red LED blinks 4 times which means fan failure of the fan that is part of the lamp module. Already returned initial new lamp and got...


Not sure if this helps with the 7200 bu had a 4805 with a failed fan issue. There are two fans inthe unit, one smaller one that cools the color (colour) wheel and the larger one that cools the lamp. This unit had a problem with the larger lamp fan not turning. Unplugged and disassembled the unit to get the fan out and tested the fan using a 9v battery and a couple of wires (best to uplug the fan from the controller board so you are not forcing voltage into the unpowered controller board... that said, I did it hooked up just peeling back the label in the centre of the fan and touching the wires to the solder contacts) The fan worked fine so figured the controller board was the issue, so this wasn't going to be a simple "buy a new fan" issue.

Here is where your mileage may vary...

I decided that it would be OK to just run the fan. Unplugged the fan and powered it from the 9V battery and assembled the unit and powered it up. Found that there was 7v available on the power board at the second pin that was alwasy on when the power switch was on (thats the positive 7 V pin, but measure it with a meter since we are talking about a different projector) and just wired the fan direct to pin 1 and 2 (1 is ground on the 4805, 2 is +7V) and so now whenever the main power is on the fan runs, so after ti cools down I just power off the main power when not in use... or let the fan run if the noise isn't an issue. Crude but effective fix.

Hi there

Replacing the lamp won't make any difference at all.

If you have checked the fuse on the Powersupply Board and it tested ok , then the whole Board will need replacement.

Power LED blinks red


it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea

From the manual...

The POWER LED
and LAMP LED are
blinking
alternately.
• It may be a malfunction that the fan is locked or the temperature has increased.
The POWER LED
and LAMP LED are
blinking rapidly
simultaneously.
• The lamp may not have been installed correctly, or it may be due to a malfunction.
• The lamp door may not be closed correctly.

The LAMP LED
continues blinking
• It may be a malfunction of the internal electrical circuits

Unit will not Power Up.


Hi, we had the same problem... Bought a new lamp and then encountered the power light blinking repeatedly problem. After much frustration and anquish, we finally got it to work again... The way I did it was, take out the power cord from the back, then hold down the power switch and re-insert the cord. Somehow it made a difference to the unit and it powered back up all fine.. Cos we heard the fan come to life properly.
Cant guarantee it'll work for everyone but give it a try all the same.
Good luck
