Hitachi 53uwx10ba wont shut off

Unplug, wait 5 minutes, plug back in.

Hi

I know this may sound silly but have you tried starting it up with the power adapter switched on and plugged in

GO BACK TO XP OR GO TO 7

Do a reset on your 2wire by pressing the reset button of it for 15 seconds while power is ON and then after that power it OFF for 10 seconds and then reconfigure your unit and check if its working already....

no,what are you doing is right.when your PC wont to shutdown,that mean is somethings wrong with your PC.
you better to reinstall your Operating System.

the regular problem is the convergence kit,

Same problem. Replaced both convergence ICs about 5 months ago. Worked fince since then and just recently no sound, no video, blinking red on front panel and clicking sound. I suspect that the ICs went bad again and blew a resistor or two. I used cheap Chinese ICs instead of the Sanyo ones and thing this is why. I'll be looking at it again and post solution.

replace the convergence ICs you can get replacement ICs at the following link with free installation instructions. Use two STK392-150 ICs they are good durable ICs for your model,
Heres the link.

you have a sensor problem to start magic focus is the last step in this repair done normally after replace converge outputs did you do this? if so a manual alignment is needed then you may write it into memory if you get a solid green screen after just briefly you have done it wright if you get a red screen after wards you need to try again it will stop on red if all is not well
