Epson Projector EMP-TW20 Schematics or service manual

[Guest]

I had an Epson Projector TW-20 for years. Already operated ~ 1300 Hr. However, recently the bulb can not be on.

I openned the case, and try to fix it. Occassionally the bulb was on for twice. (But still can't be on for many trials) So I suspeted there are something wrong with high voltage section. (The bulb always with a weak sparkling of light for less than 1 sec. when power on, but never be lighted after.)

Please if you can support me the schematics or service manual? Or if you have any suggestions. Thanks!
