Question about Hitachi 50V500 50 in. HD-Ready LCD Television
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.
