Question about Hitachi 46F510 46" Projection HDTV

6 Answers

Convergence (?) Had a problem a couple of years ago - a TV fellow came out, opened up something, aligned (?) some lines, cost $200. Went out again, and then while moving the TV back into its proper place, I bumped it against the wall - and lo and behold the color was ok again. It now went out again. I bumped it, moved it, etc., and still out - I cannot get the remote to fix this and do not want to spend another couple of hundred dollars - almost feel like getting rid of it and getting another TV. Can you help? Thanks Glenn Benson

Only option is to check the IC's see if one is blown and if so identify it and replace it. But i feel leethedeuce has the best solution on the matter.

I heard at some point that having a strong magnet could fix color related issues. don't quote me on it, but taking a magnet to the bulb could have a positive effect on this.

Good luck!

Replace the television as you most likely need the 200$ service. Buying a new tv is much more cost effective.
Keep me posted if you need more info.
Thanks,

    I do not know how a magnet would help. I hope you will accept my solution and if you need further assistance don't hesitate to ask.
    thanks,

    Like I previously posted you have the answer yourself it is not worth the investment to fix. You can sell it on craigslist for parts. Buy a new Hitachi. If you want to feel real safe by the 4 year warranty at place like circuit city. Once a year you can have a professional come out for free and have the color guns aligned. It also covers power surge protection and other things.
    If you found any of this helpful please accept my solution and rate accordingly.
    Thanks,
    Lee

>reseat the bulb - take the LAMP out and put it back in
>powercycle - turn the TV off, wait for 3-5 mins, then turn it back on

>if bumping the TV again does not fix the issue, add previous bumps, NEW TV SET is the best recommendation

Replace the convergence IC and check power resistor for leakage, if values are not exact replace them. Once the parts are in place perform the alignment.

The bulb must have been dislocated

    Try to reseat the bulb and do a power recycle that should take care or else you have already decided to get a new TV SET so that would be the best choice

It sounds like it has cost you a fair bit of money over the years. It would be great to get it going again but if you stand back and look at what it may cost, would it not be wiser to put your money into some more modern technology?
Convergeance errors are unlikely to be easy fixes. I expect the power supply is getting noisy and producing distortion on your picture. Replacing the many aged capacitors will possibly repair it.
Hope that helps.

Red color convergence issue; Red lines are curved


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!

this indications that you have a problem with convergence. first try to go into customer menu...setup....convergence. and see if the convergence will adjust.. if it wont then you have a problem with the convergence cuircit boards.
