Where can i buy a infocus control board 510-2111-00

Without a remote control; you can't. If you wish to buy its original remote control, contact the authorized service centre, or authorized dealer to your device brand. They can either give you a genuine remote control to your device, or can direct you, from where can you purchase a suitable one.
To select a proper universal remote control, you should know about the number of digits to its set-up codes. There are 3 digit, 4 digit, 5 digit, 2 digit and even single digit codes, to some brand devices. After confirming this, check the sites linked here. Both the sites have set-up code list and set-up procedure to many popular brand remote controls. Check which brand remote control has set-up code/s to your device brand, and buy that one according to availability. Brand name of the remote control isn't a matter, but it should have set-up codes in its code list, to the device brand you have.
Please note: Every new universal remote control will have set-up code list, and set-up procedure along with its pack. Never accept a remote control, that hasn't both of this. For more details about the set-up codes, visit the sites.

Universal remote controls are available at most of the electronic spare part selling shops. Visit some on-line sites too, which deals with electronic spare parts.

reset the settings to factory default. if that doesn't work, you may need to have the eca controller (main board) replaced. unfortunately, infocus no longer carries parts for that model anymore.

you have a problem with the main controller board. unfortunately, there are no replacements from infocus. sorry.

but try to clean and resolder the edge connector (looks like silver fingers) contacts on the power supply where it plugs into the green plug on the main board. the main board may be getting fluctuations in voltage due to poor contacts.

good luck. infocus has nothing having to do with any of the lp4xx series. they don't even have lamps. try ebay.

you won't find schematics for them. infocus had their boards made by someone else who now no longer makes boards. it's usually the caps drying out that causes power problems.

Hi there

I just sent you an email through fixya and I don't know if it went through but I was just saying about the fan and the grey bar. The problem with the fan, is not the fan itself, but the controller board not supplying enough voltage to the fan (you can see this by powering the fan on its own using a 6volt supply, you will fine that the fan will work perfectly normal), thus having to replace the entire control board at around $650+, this is a very common fault for these models. The grey bar as meantioned in my post is caused by the faulty light tunnel, there is a link I've posted here somewhere which tells you how to fix it, but you need extremely strong glue and electronics skills lol, otherwise infocus wouldn't sell me the part on its own, only the whole optical enigne at another $450+. Very poor service in regards to infocus.

Cheers

A bit unusual for the projector to stop responding to the remote. Usually it follows when someone has opened the projector, they forgot to reconnect the controls from the case top which also includes the IR receiver. If it isn't that, it could be a broken IR pc board or bad connection. I've seen that.

The worst case is that the IR controller on the main board has failed and if that's the case, you'll have to live with it as the cost of a new board is very high.

The cost of a new controller is prohibitive. If you have to replace that, you may as well replace the projector. It is the second most expensive part in the projector, the optical engine being the most expensive. Last time I checked, a new Controller Board assy is in the neighborhood of $800 - $900.

ebay has several that need bulbs... just a thought here is one of the item numbers Item number: 270207032811
