Hi the blue line on my hitachi 60'' wont adjust. i tried magic focus and i also tried doing it manually. i managed to adjust my red line but when i try to adjust my blue it just wont budge at all. i checked all the lights on the board and they all seem to come on. can anyone help me out with this problem. i was thinking it could be the STK but im not quiet sure can u tell me if i am right or if it can be soemthing else. thanx

This set with front grill removed has a tiny blue button on front edge of chassis on left side that will manually take set to convergence mode but you must have the Hitachi working remote to do adjustments---different buttons on the remote adjust and save the adjustments, I have the Hitachi book that shows all remotes they use and which buttons do what---if convergence is real bad most likely the two chips for convergence need to be replaced if Magic focus will not help.
Sounds like your blue convergence module is faulty along with a few resistors.
There is two convergence modules in your set(stk-392-020) and when one fails, the both of them are usually replaced with a matched pair .If you have a good knowledge of electronic you may replace them yourself.otherwise you`ll need the help of a tv repairman.
Hope this help. Good luck
Try adjusting the convergence. If it won't move see below- (or hitting Magic Focus for some Hitachi’s) This sounds like 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 charge between $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
if magic focus will not correct convergence problem look in the customer menu for the word CONVERGENCE---IF BLUE WILL NOT ADJUST IN some direction, one of the two Stk-392-110(or 392-150) convergence Ic chips are bad; you may also find some burnt or discolored resistors behind them----this kind of problem is usually fixable right in your home; if you need direct help;;;
If this was helpful I would appreciate a vote from you here.
Maybe the best way to adjust the screen is with the manual magic focus..instead of letting the tv do the auto change it to manual and see if you can adjust the convergence yourself. I have this same model and once in the manual adjustment you want to make sure you see all white lines....if you seen any blue or red that is the color that needs to be moved towards the white line closest.
Once you think you have it lined up nicely hit "exit" on your remote and option 1....
