Capacitors are usually Blue or Black (Black on most optoma boards) and look like little cans. In most of the board I have seen online, if you have the power plug port facing you, the caps should be on the far right hand side.
Be very careful when dealing with capacitors, they will hold a charge for a very long time and can be deadly if the pins are shorted.

If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

It will be difficult to get. If the space allows, you can use 3300MFD 16V capacitor in place.

Hello
if replacement lamp has done, was the lamp timer reset after replacement? and if the lamp is original, there is either a bad lamp or a cooling problem.
Good luck

if it is a DLP projector then the DMD on the engine is likely bad or the main board is bad. The white things are pixels.

My optoma es526 came with a 7year colour warenty,try ringing up optoma and send your projector to them or try replacing the colour wheel.

The only thing I can think would be that the projector is heating up because the air filters are clogged.
