Changed the bulb 3x. dusted off the intake valves in the front of the tv. tried to reset the lamp bulb. still flickering. from my understanding if the ballast board is bad/going bad the tv should either not come on at all or turn off by itself. my tv does neither of these things. after you turn it on, the picture is GREAT and approximately 30-45 minutes later, the color starts to flicker. the picture is great again.....then flickering color and good color...then the color is gone. wth?!?
The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

Your crt is leaking coolant onto the board , you need to rebuild whichever crt's are leaking and fix the board!

Its far more likely the result of the power pwb capacitors that have failed. As the 34 code will appear if the capacitors fail on the Power PWB. You can get the V26 DLP Power repair kit at the following link.with free instructions

There is a tiny reset button to the left of the timer light. Press with a pin or something small, wait 60 seconds. Viola!

Could be the FMT pcb or the Dm pcb board you should check the caps on them and replace any faulty ones.

What it sound's like is that the lamp ballast is the problem. Buzzing sounds like when the power is first brought to the ballast it has to ramp up the voltage to get the lamp to light, then the voltage drops back down when the lamp is lit. Sounds like the lamp ballast isn't ramping up the voltage the way it should. May have to replace it. A good service shop would be able to do this for you.
