I replaced the bulb and ballast with Philips upgrade and the set came on with 
normal picture. I then tried to reset the timer lamp by entering service mode 
and the lamp would not start up again no matter how many times I tried. I took 
it apart and realized the color wheel was not starting so I manually tried 
starting it with no change. I checked voltages to ballast and both 5v and 138v 
checked ok. I suspected bad ballast and got another one with same results- 
initially starts up then will not come back on after shut down. The customer 
said it was very tempermental and would not always come on before the bulb 
finally blew. Lamp led blinks then cycles on and off three times with sound 
then shuts off. Anyone seen this? Any help would be appreciated. Thanks, Tim
