Question about Hitachi Office Equipment & Supplies
The bulb would not affect the focus. You have a problem with the TFT panels in the light engine. The only solution is a new light engine. Last one that I installed cost $350. I would think that you may be able to install it yourself. Basically it is the entire assembly inside the unit minus the power supply and video in/out boards. Here are some web sites where you can get the best price on the engine www.encompass.com or www.shopjimmycom or www.partstore.com . Let me know how you make out.

Once the lamp is replaced it is essential to reset the timer back to zero or the lamp WILL not work.
Lamp Life – Projector lamps have a finite life. The image will become darker, and hues will become weaker, after the lamp has been used for a long period of time. The length of the lamp is normally 2000 hours, on the screen there will be an indicator giving you adequate warning that the lamp is reaching its 2000 hours. (The lamp will automatically switch off after the 2000 hours and will not go on again – THIS IS A SAFETY MECHANISM TO HELP STOP THE BULB FROM EXPLODING). At this time you need to be ordering a new lamp.
if the lamp is new and lamp brightness is coming properly then its the problem of loose connection for this fuzzy image.remove all the connections and reconnect again properly and tightly at their respective ports/sockets. then check out.if still the same problem of fuzzy image comes up then check out the front lens from where the light ray from projector comes out.if that front less is dusty or not cleaned properly then also this happens.clean the front lens with a dry cotton cloth and check out. if there is no dust and every thing cleaned and bulb is properly glowing then its the problem of the internal circuit board of the projector.
the circuit board needs to be checked with a meter and the faulty components on the circuit needs to be replaced.
