Toshiba MT8/Infocus 7200 broken power board

My tosh MT8 (infocus 7200 clone) has a a power fault. When switched on (from fully off) it emits a clicking sound from the power board before eventually coming on.
Now, it refuses to come on at all, just clicking at different speeds.

I've been told its a power board problem, which I'm happy to swap out myself if I could only find a replacement part!?

Toshiba are of absolutely no help with this issue.
Can anyone help?

thanks

Can't start infocus sp7200 after changing lamp.


The end of lamp timer has reached it's limit and won't let the new lamp strike. What you need to do is Reset the end of life timer. To do this, with the projector switched off press and hold both the up and down Brightness buttons on the projector. while holding them in turn on the projector. Continue holding the buttons in for 10 to 15 seconds This will reset the end of life timer in the projector.


Cheers

Infocus x1a fan replacement


to remove the fan: remove the 8 screws from the bottom of the projector (4 silver, 4 inset and brass) and the 2 screws from the back. pull the back from the bottom, but use a small flat-head screwdriver to release the tabs seen through the topmost vent of the back. once off, unplug the speaker wires on the right and the cable harness on the left. pull the top off while pulling the front off from the bottom. remove the wire harnesses from the power supply board and the ground wire from the power input board. take the 4 screws off of the power input board and the 4 or 5 screws from the power supply board (and 1 center clip) and remove. take out the 4 or 5 screws from the metal shield and remove shield. now you can unplug the fan that need replacing and access the 2 screws holding the fan in. remove fan and replace with a like fan. since the fan speed is not monitored, if you can find one that's the same size, power, and plug size, use it. otherwise, contact an infocus service center and ask them for infocus part # 526-0192-00. reverse instructions to put it back together. but you must remove the front from the top case, put the top on first, plug the speaker and left harness in, then put the back and front on. wasn't that fun?

I have a Infocus SP7200 projector that will not power up. The power led is not turing on. I have tried different plugs, etc. I believe the problem is inside the projector but can not determine how to take...


One way of telling if its the power supply is apply power to the projector and look at fans on the side. If they don't move then its a power supply issue. The case is only held together with 4 screws. Two in the back and two underneath. The and then it just snaps apart. I'd be careful in there since there are some delicate optical parts. I can fix this for you for less then it cost to send to infocus or to a repair shop. Ebay Id is Gtitubro

Infocus x1a fan replacement


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

LP540 INFOCUS


good luck. not even the infocus authorized service centers get those. besides, they were made by another company that does not make power supplies antmore. and infocus doesn't have any new ones in stock. if you're getting no power at all, replace the mosfets. it works half of the time.
