Question about Toshiba 72HM195 72" HDTV
The original problem was continuous flashing blue light. Replaced the projector lamp bulb opened the unit up to check for other physical damage and found none. Now when I power the unit, the blue power light will not come on after boot. Only item apparently operating is the fan for the PC boards. Does anyone have any ideas?
Yes, I've seen the ballast bad after a lamp shorts out. It takes out a 1K resistor out in ballast. If original lamp blew up this could be your issue

SOURCE: Toshiba 52HM95 Light Engine
this is the worst investment I have ever mede after replacing the bulb for every six months the color wheel goes out and its 750 to repair
basically after the initial arm and a leg the TV came back for the other ones And the customer service from Toshiba is even wors than the TV I guarantee you will end up cursing at them before you hang up in there face after the smart *** remarks If you buy this TV your as stupid as I was
Toshiba is the worst brand to buy

You could have gotten a defective lamp. Try another lamp. Since you have a Toshiba youll be using it even if you don't need it now. Toshibas have short lamp life. If lamp does not fix then the light engine will have to be removed and sent to Toshiba to be rebuilt. They are no longer available.

I found R3 on the original board to be open, along with reading an open on CR1, D5 and D6. All the other transistors and the transformer check out. The only thing I have to do now is find out the specs of the diodes. The replacement board also had CR1, D5 and D6 open (R3 was OK). There had been some threads on various locations where remanufactured boards had bad components (the transistors were changed but not some of the other components).

the fan has (maybe - check it) a filter screen between it and the outside air... cleaning this filter will increase airflow.
cooling fans are really cheap and its a good idea to replace a fan that has had a hard job in a hot environment BEFORE it fails...
sorry, I dont know how to open the door though... maybe you'll have to take the entire case off... then you'll see how the door comes off for next time anyway - if you're "servicing" the set you could do worse than get the case off and clear the dust out.
