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?

switch ignition on, engine off. fully open window fully close window, lift and hold window close switch until window motor emits a clicking sound, repeat procedure for remaining windows,switch ignition off. sound like battery been replaced disconnected, if this procedure dont work let dealership check it out.could have blowed window switch fuse to that door.
Here you go,
This is the search section - turn your Tosh over and find the product label...
note the details they want and fill them in - IF you can connect using your Tosh... just click Auto detect... then look for the drivers you want (note there may be more than one.. choose the latest...)
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.
I had exactly this problem. After plugging and unplugging it multiple times over several weeks (even plugging it in quickly after it was unplugged but with the green light still flashing as suggested here) all to no avail, it just started working on its own one day. It worked for a few weeks and then the problem re-appeared.
InFocus tech support recommended: 1. Check whether the lamp door is securely closed. 2. Check the color of the LED and the number of time it blinks. (For me, a very fast almost flickering flash) 3. Does the fan operate? (My fan would go on when plugged in) 4. Remove the lamp module, shake it gently and reseat the lamp module.
For me, these steps did not work. InFocus then recommended that I send it to ProjectorDoctor http://online.projectordoctor.com/, and it was diagnosed with a bad power supply. $395, but it is fully functional again. Good luck.........
I had pretty much the exact same problem, I could hear the fans turn barely on when plugging in, but it wouldn't power up. If you look at the power light in dark conditions, the light was doing a rapid flicker. My power supply had failed. I tried to get a replacement board, but the part is no longer available. Projector Doctor would fix it for $395, but there is a person on this board who goes by Neo32 on here and gtitubro on ebay that fixed it for me for $150. I'm a satisfied customer :-)
