Hitachi 53SWX12B Convergence Problem and blinking light
My 53SWX 12B projection TV was repaired a year ago for convergence and sound board problem. The convergence went bad again and about a week later the TV shut down and now the only thing I am getting is the power light is blinking, no picture or sound. I've checked the fuses and the check out. I did notice that the LED light on the different electronic board are also blinking. I am getting good power to the set, but have no clue what is going to the differnt components. The nearest repair center is 100 miles away and they want $2.50 a mile plus $90.00 eveluation fee. I would like to try to fix this myself if I could. I do have access to meters, soldering irons and some technical people who can help. Any idea what is next. I would like to repair the unit if the cost is not out of this world. Thank for any help.

Im thinking your convergence chips is causing all of your problems but here's the fix to the convergence: http://home.earthlink.net/~oleg.filippov/ConvergenceFix.htm http://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-ii.html

The tv have a problems known as a convergence problems,it dead.Tv have R,G,B colors lines mis alignments,have colors shadows pictures or 3D pictures look alike?The tv have a dead convergence board,tv convergence board require changes 2 STK convergence ICS and some or all of it resistors too.Fixed the tv convergence board will solved the tv convergence pictictue problems.The shop,will cost u like $300-350 for parts and labors.
Flash Focus magic button no longer work.The tv have a problems known as a convergence problems,it dead.Tv colors lines R,G,B mis alignment,have colors shadows pictures or 3D pictures problems.The tv convergence board the 2 STK convergence ICS and some or all it resistors are dead.These parts,must be replaced on the tv convergence board to solved the tv convergence picture problems.The shop,will cost $300-350 for parts and labors.
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 $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
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.

The 392-150 is a higher current device then the 110---you can use either--this is normal in the hitachi sets---I usually replace both with 150's---check the led that does not light---should indicate which voltage source is bad---if it is one of the 2 voltages for the convergence ic's(one is a positive and the other a negative voltage) then the convergence Ic's may be bad---look for any discolored resistors around the ic's---one way to tell if it is a convergence ic is to de-solder both ic's and see if the set turns on(the convergence will be out the window) but if it comes on change both and do the alignments with the Hitachi remote. By the way----the led should have a location number printed on the top of the circuit board.
