Neighbor got new TV, gave me his old one. Son and I were looking for an electronics repair project, and this found us. Neighbor said this one needs high power board, otherwise fine. Very good condition overall.
Any suggestions on where to find? Checked ebay, nothing listed for this model number.

Hi, Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
The colors seperating is a convergence problem, as far as being dim this may be related but the TV likely needs service adjustments. convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks! See link for more detail http://www.ehow.com/how_4575598_yourself-projection-tv-repair-convergence.html
you need to replace the convergence ic's these are the stk-xxx-xxx chips found on heat-sinks
on or around the main chassis don't adjust the tubes or anything else this will only make things worse after you replace them you can do the user alignment also check the values of the resistors in the circuit as they may be off now pay close attention to the resistors that have a value less than 10 ohms these are critical to the correct alignment if in doubt replace the resistor.
