It could be high voltage cap located by flyback,if you have back off of tv and turn tv on,you will see green led's turn on,(on the board)if they turn off there is a small blue high voltage cap hidden under glue(i believe it's a 102 cap)that would be the one change,99% of time that is what will fix problem

This should be a menu option in the video portion or initial set up area of your menu. If you have auto converge it will do it for you otherwise it will put up a screen with color patterns for you to manually converge.
Did u check the pico fuse and all those resistors on the tv convergence board to make sure with ones are good resistors which are not good resistors and replace all them resistors too?U didn't do that should get it tested and replaces all those dying resitors.Try website like Tvrepairworld.com look up ur Hitachi tv model what resistors and pico fuse u require to check.
Ur tv have a problems known as a convergence problems,it dead.Tv have corlors R,G,B lines mis alignments,have colors shadows picture or 3D picture look alike?Yes.The tv convergence board is dead.The convergence board must change 2 STK convergence ICS and some or all of it resistors to fix the convergence board to solved the tv convergence picture problems.The shop will cost u like $300-350 for parts and labors.
No there are no quick fix options for this fault. The convergence amplifiers operate similar to a high power audio amplifier, so if there is an impairment anywhere in the system, it will result in distorted audio, or in the case of television convergence amplifiers, a color won't align. The convergence power pacs need to be replaced and the out of tolerance precision resistors located near the power pacs need to be carefully checked and replaced as necessary.
It is also possible that there are root faults that cause the amplifiers to go bad which include bad connections or a bad digital control module. This repair is possible for anyone having basic electronics knowledge and soldering skills.
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.
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
Good Day, Gil;
Your problem is in deflection circuit (115+v) check these: FP05, DP15, Q777, QH01, TH01, T701, etc. BUT suspect C707 1k pfd, 2kv, and check all the pico fuses (brown) 2" to the right of cap. Good Luck, big IRISH.
it sounds like your blue convergence ic is getting weak you need to replace the ic's STK392-110 and you should replace both because when 1 is bad the other will go real soon. They are inexspensive at the sight I posted and you will also get free tech online support if you purchase them there. http://servicemanuals.vstore.ca/
