Need Help with Pinstriping on Meridian MF1/JVC HD10K

After recently getting the power supply replaced on my Meridian MF1 (tweaked version of the HD10K) when I unpacked the PJ from UPS shipping, I saw vertical striping in the pictures below, which were not there previously. Reading about striping with the HD10K several users have said they found it to come from loose connections in the machine.

Normally I'd ship it back to shop (the Repair Shop near Atlanta) but I'm in VA and RT shipping is $300 and I think its the shipping and shaking that caused the problem. After talking to The Repair Shop I have disassembled the PJ twice and tried tightening all of the visible wire connections, but gotten no improvement.

QUESTION - Does anyone 1) know any other causes of the striping in pictures below, or 2) know which connections in the PJ are likely to cause striping? I'm happy to disassemble again and try tightening connections I may have missed.

Thanks for your help on this - its an excellent projector when its working.

Hi,

The most common cause for stripping issues is a bad connection between the image panels (LCD, LCoS, whatever) and the main board. The problem is that complex projectors like JVC’s don’t usually connect these cables directly to a main board, they have a dedicated image processing board. On the other hand, stripping as regular as shown on those photos would seem more likely to be caused by an issue with an image processor board itself, while bad contacts usually produce a more or less irregular stripping. Besides, JVC projectors have high quality connectors usually pretty well attached and shielded. I don’t think this is the kind of issue you can fix just by reseating some cables. My X30 has a similar occasional issue with the red color panel, and I don’t think it comes from one of the main contacts of those cables.
