Question about InFocus LP640 Projector Multimedia Projector

1 Answer

I have an Infocus 640 that I'm thinking of repairing. It won't power on correctly. If I hook up a regular power cord to the back and bend it slightly and press the power button, the unit will power on for a second. I'm thinking I could switch out the power supply pretty easily. Is the power supply the same as the 540?

Firstly why not just resolder the main connector on the pcb of the 640 unit. then check if your problems will be solved.

Otherwise look at the part number of both power supplies and see if they are the same.

My electric wrap continues to blink and not come on regular! What do I do??


You may have a damaged power cord or a defective thermostat in the electric wrap. Unplug the cord and inspect it from the plug to the wrap. Look for crushed and broken wires, especially near the plug and at the wrap.

Plug in the wrap and note the rate at which the wrap's indicator light blinks. If the blink rate is regular, the thermostat may be defective.

If the blink rate is irregular, CAREFULLY and gently flex the power cord while watching the indicator light. If bending the cord
changes the blinking rate, you have found the area of damage.

If the problem persists, unplug and discard the wrap. Repairing broken internal wires can expose you to an electric shock or cause a fire when you attempt to put the "repaired" wrap back in service. Your best strategy is to discard the defective wrap and buy a new replacement-- the safety risks are much greater than the price of a new wrap.

Usually the manufacturer's owners manual has a part list with phone numbers and part numbers available for replacement.
If the correct part is not available, you could buy a similar sized gauge extension cord to wire in place by taking the appliance apart and securing properly.
Last but not least and certainly not recomended would be to wire in that extension cord with wire nuts and then electrical tape together. Good luck!

Pull Cord has stripped and won't recoil. Can this be repaired?


Stripped? Maybe the recoil Spring just broke. Easy repair, sometimes you can just re-bend the 'Stop' on the old Spring

NEED A REPLACEMETN POWER CABLE FOR LEXMARK 640 COLOR JET PRINTER


If that is a T640 printer, it uses a standard computer power cord.
Any one will work, but if you can get a right angle plug on the printer end, it will look and fit better.
NOTE! If you get a right angle plug, make sure it bends the correct way (the plug only goes into the printer one way, and if the plug bends the wrong way it won't fit).

After connecting power cord, led turn solid orange, upon pressing the power button led blink green one time only then it return to solid orange again... i'm using Infocus LP70+. thanks


the power supply needs to be replaced. the caps are dried out and powering the projector causes too much of a drain, so it shuts down. you can buy the part from an infocus service center and do it yourself, or send it in to them for repair. either way, try www.avsolutionsny.com. they're really good.

In72 does not power up. I think that it is a blown fuse. Where is this fuse located


if there are no leds lit on the top, then it's a power supply issue. open it up and check the fuse on the power supply (next to where the cord plugs in). if the fuse is ok, you'll have to replace the power supply. you can get parts from an infocus service center or send it to them to repair. either way, try www.avsolutionsny.com. they're really good.

HP VP6210 won´t turn on at all


try to replace all the capacitors on the motherboard. This are the only parts that leak in time. Try otherwise to reset to counter or update the firmware on your machine on the infocus site.
Goodluck !
