LCD rear prjection TV's do not have convergence amps.......
Problem is rightly called ghosting....Your Hitachi- experienced
service tech will check the ghost adjust at I2C menu pg.57 in
service manual. Or research ghosting at HitachiServiceUSA.com
Hope that helps.....T.

Is anenvolved job to repair a convergence problem,the way to go about it is to locate the convergence amplifier IC's,one for each color(red green,blue)check for loose conections at the ic's legs,after resoldering all the legs see if an improvement is present if it gets better you will be able to adjust from the custumer controls,but if no improvement the Ic's will have to be replaced.Some units have a separete board were you can adjust convergence after replacing the Ic's and other units you have to access the service menu to be able to do the adjustments but just doing this adjustments can be very challeging even for a train technician,I would suggest you seek assistance from a servicer and get an estimate.

Ghosting or a 3D image. A yellow and blue ghosting or shadowing image. Looks much like the top picture in the "picture ghosting image" entry. Is this a convergence problem?

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

I have a Sony projection TV KP-53HS10. From one

It is most likely the convergence board. Rear projection TVs use three lights to display the image. The image is aligned via the convergence circuit. After many many hours of use the capacitors and resistors on the board lose their tolerances. It is very expensive to repair if you take into account the price for a new TV and the quality of the image you will be getting if you do have it repaired.

I have a jvc projection the top of the screen is misaligned (drooping)convergence dosent help whats wrong

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!

Double image, green and yellow ghosts, blurred image - Flash Focus does nto do anything, convergence adjustment does not work at all

That means convergence out ICs are not working, requires replacement.
