Witam.
Projektor po wystrzale lampy. Oznaczenia płyty głównej: 4H.1YU01.A01, poniżej zdjęcia:

Po rozkręceniu wyczyściłem projektor ze szkła, zablokowana przez kawałki szkła była turbina chłodząca lampę. Na chwilę obecną projektor się włącza jednak nie daje napięcia na 2 nowe lampy, które podstawiałem i są sprawne w 100%. Ponieważ projektorów nie naprawiałem, proszę o pomoc od czego zacząć sprawdzenie?

Hello!

Does the projector report any error (any LED is on or flashing except the blue power LED)?

No, 3 blue diodes lightning like normal working. I forgot to write, when the bulb exploded, the fuse in the box in the flat turned off.

Measure the voltage between points A and B (not to ground, but between the points itself), when the projector is turned on.
Be aware of high voltage.

Check the transistor Q651.
If it's good, measure the voltages on all pins of this transistor in reference to the "hot" ground, when the projector is turned on.
The "hot" ground is the negative pole of the large (450V) capacitor near that transistor.
Be aware of high voltage.

I checked Q651 - it was damaged. Today I put on a new one and now I have 385V on legs A and B which were marked in the previous photo. The lamp is still off.

Check the listed components on the ballast board:
- All five power transistors (marked yellow).
- Power diode (marked red).
- Both coils (marked blue). As for the coils, it's enough to just check if they have a low resistance.

2 transistors on T4 and T5 (STP30NF20) were damaged, they just arrived and after the change the projector is alive. Thanks matic for your help.
