I have a 3M MP7720 projector, unfortunately the PSU board has failed and blown T101. Can anyone tell me what IC T101 is as it is completely destroyed so I can't read any identifying information. Thanks

Chances if that got destroyed, it took out peripheral componets as well. might as well replace the board.

Need a power supply for a pmh5000 and install directions


These are delivered with a power supply. If yours has failed, LIKELY there are other problems. I have repaired several supplies and can coach you through which parts to replace. Often the failure originates with a shorted MOSFET in one of the amplifier channels, usually the rearmost one. Getting parts for these is really hard as FullCompass is the Behringer parts distributor. The SPS1000 supply takes out about $25 of parts when they go. The hardest parts to replace are the IGBT transistors as the heat sinks are hard to remove to get the screws out of the transistors. All the repair parts are available using five different online sources.

Simply fails to switch on. Mains fuse OK "Special" fuse of PSU board OK.


Check the lamp door. There is an interlock there that will prevent power-up if the door is open at all It should be a small post on the door that enters the projector to compress a micro switch. If the post is broken or the door is not completely shut, the switch won't activate and there will be no power.

If that is not the case, please update this and we'll lok further.

Thanks,
Dan

first reset the settings to factory default. you may have to realign the lcd panels and make sure the panel ribbon cables are properly seated. otherwise, you have a main board issue.

Loud Bang and Projector no londger works


If the internal fuse has blown, if you connect the power lead loosely and move it about, you should not be able to hear any crackling sound of electricity. If you do then it is more likely something else other that the internal fuse. Generally, a loud bang is either the fuse or lamp.

No power to projector


Generally when the globe goes end of life and needs replacing the unit will fail to power up. Try another globe if you have one spare.

Tv cuts off 10 seconds after switch on and destroying vertical output ic


If the main IC is not putting out a vertical drive signal then the vertical output will not do anything and therefore will not be damaged. What exactly do you mean by the set "literally eats deflection IC's"? What is the number on the vertical output IC? I will bet that your pump-up cap or pump-up diode is defective.
