Sounds like the convergence board, try replacing the STK voltage regulators and any resistors that may burned or discolored. This problem is causing the power supply to shut down probably.

Projection TV red is drooping


Do an internet search on "Hitachi Convergence Circuit". This apparently happens all the time. TV repairmen charge about $400. Parts are less than $50 but you would have to be an expert at soldering electronics circuits to replace it yourself.

My TV had the Blue misalign instead of the Red. I ordered the kit #9 from http://www.bdent.com/search/part.jsp?partnum=KIT9

DO NOT ATTEMPT IF YOU DO NOT KNOW HOW TO SOLDER. YOU WILL PROBABLY RUIN YOUR TV.
