I've been searching the internet(s) for help with this and thought I would come here for a hail mary. Any projector guys around here?
I purchased a used JVC DLA-RS46 projector and its been working for a few months then all of a sudden this happened.

I noticed that there was a slight flicker in the brightness so after searching I thought it was the issue with the bulb filament that needed to be run on high for a while to attempt to correct. After running this for about 30 minutes I started to see the image jumping. no longer just a brightness issue but the image itself jumps up and down.
Seems like it comes and goes. Sometimes it gets worse sometimes it will go away fro about 5-10 minutes then it comes back.
There was one time that it was happening and i hit the reset on the picture mode and it went away for a few minutes then came back. Reducing the bulb to low mode didnt seem to do any good.
Also tried high altitude mode and eco mode with no luck .
It seems this was only happening when there was a source playing though it. I use a HTPC and I tried a laptop with the same issue. Also tried multiple hdmi cables and eliminating the receiver.
If I have the grid patterns displayed its fine.
Any suggestions please? the only issue I have been able to find is the bulb filament issue but this does not seem related.

I recommend checking on AVS forum. They have several owners using the JVC-Ila and a familiar with most issues
May look up HDMI convergence issues, there is a firmware release that must be loaded via RS232 serial2-channel: Modwright KWI-200 Integrated, Dynaudio C1-II Signatures
