Epson CB-2065, CB-2155W, CB-2165W, CB-2245U .
When the lamp driver fails, typical symptoms include:
- The projector powers on but the lamp does not ignite (no light, no flash)
- The lamp starts but then flickers or goes out after a few seconds
- A clicking or buzzing sound comes from the ballast area, but no lamp illumination
- The projector shuts down and displays a lamp error (even with a brand new lamp)
Replacing a defective lamp driver with this genuine PHG251A4HY restores proper lamp ignition and stable operation. Installation requires opening the projector and basic electrical disconnection – recommended for experienced service technicians only.
Before ordering: Confirm your projector model matches one listed above, and check the original lamp driver board for the part number PHG251A4HY (printed on the PCB label). If you are unsure, send us a clear photo – we will verify compatibility for you.
