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:

palmer_band,

Due to the fact that you recently replaced the convergence ICs I would look at that area. Check all the resistors, diodes and semis for any problems. If none are found use my tip at http://www.fixya.com/support/r6396176-projection_tv_troubleshooting to help troubleshoot your unit.

Thanks for using FixYa and for the great rating.

Why is the picture like double vision blurry?


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.

My Hitachi TV Model #51F500 is showing shadows and double lettering (in other words a terrible picture). Please help.


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!

Green, yellow and blue images are not converging.


Try adjusting the convergence. If it won't move see below- (or hitting Magic Focus for some Hitachi’s)

Hitachi 51UWX20B no sound, no picture, blinking green LED


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.

Hitachi Projection TV will not turn on just blinking power light


There is a board on the right side of the tv called the convergence bd

There are little connectors that are on the left of the board
the last one is the power to the convergence Ic's

That is the one that is closest to you. they are little black conectors with wires in them


Carefully lift it up

Then plug the tv back in and see if it fires up

If it does do not run it long

just enogh to see the tubes light
then shut if off

If it goes on

your convergence ic's are Shorted

They have a kit for this tv it is available through local parts distributors
If you can't find it locally just Google HITACHI CONVERGENCE KIT

If you are not good with de-soldering and soldering do not attempt this repair. Remember to replace all the resistors in the kit

If you are not sure about doing this repair you should have your local tv guy do it for you


If it does not go on then I would suspect the regulator in the power supply But
Most of the time it's the ics
