Question about Hitachi 50SBX78B 50" Rear Projection Television
Hi This has a line clear picture on the top 80% of the screen But the bottom has slight red shadow (convergence?) also has a hourglass effect starting ,,now the Lines,,they go across the whole screen about 1/4 way down many lines about 4-5 inch wide distorts picture right there . the rest is a perfect picture ,, this set has this digital Convergence Magic button , does this system clear up Bad STK IC's this well while causing the lines ?
John, Hitachi site is down at the moment, if you remove the clips on the front of the IC`s you will see the numbers of the convergence ic`s, and yes they are a pain to get out, they are probably stk 392-110`s if they are the originals, you`ll have to un-solder 36 pins total to get them out, check for burnt resistors in the general area of the ic`s and replace any that are burnt before turning the set on,be sure to order a tube of "heat sink compound" to apply to the back of the new IC`s, once on the set will probably still look poor, this is normal, run the set for minimum of 15 minutes then push the " magic focus button " inside the front door panel, after it has finished running magic focus it should look great, video-tek
