Question about Projection Televisions
SOURCE: TV won't turn on
problem is fan stoppage this is probable caused by excessive
dust in fan take off back and locate visually the cooling fans in unit
use canned air to remove dust until fan moves freely. if all fans
are clean maybe one fan is not giving rotation detect signal
look at voltage on white or yellow wire from fan s/b 5v then 0v
when fan rotates if one stays at 5v replace it

That is indicating that the convergence circuits have shutdown the set. You will need new Convergence ICs. They should be STK392-110 or STK392-120 either number works the 120 being the better chip. I will post a link where you can get the new ICs and they provide step by step instructions with pics so you can do the repair yourself. You will find your IC numbers under the section titled Convergence ICs just click on that and you will find your STK numbers.

This is straight from the service manual (I'm not sure what the problem is but it sounds serious):
8.2. Power LED Flashing timing table
When an abnormality has occurred, the protection circuit operate and cuts the power supply. At this time, the defective line can be
identified by the number of flashes (red) of the power led indication at the front of the unit.
NUMBER OF FLASHES CIRCUIT MICRO PIN
1 LOAD SHORTAGE 92
2 OVER VOLAGE 93
3 FAN SOS 94
4 MAIN 3.3V 88
5 LAMP DISABLE 61
6 GC3FM-IIC IIC
7 GC3FS-IIC IIC
8 GC3I-IIC IIC
9 COLOR WHEEL STOP 110
