RS20 Upgraded to RS35 Performance
Jun 20th
I recently sent my JVC RS20 in to correct a problem with the lens shift mechanism. When the projector was returned it noted that the optical engine was upgraded. After installing and testing this unit it now performs like an RS35. It is much sharper than before, has near perfect color More >

I have found two things that can reduce plasma buzzing sound levels. One is to reduce the contrast (light output). The second is to eliminate a ground loop as shown here http://homecinemaguru.com/?page_id=211.
Maintaining Front Projector White Balance

These were born in the past due to More >
LED LCD Display Observations
Feb 11th
I am seeing LED based LCD displays now that are over a year old. It appears that they are losing light output much more than expected. On/off contrast also seems to fall significantly along with an increase in the corner flashlight effect with time. The most reliable flat panel technology I have More >
