    I don't know what your technical abilities are, first check horz. transistor if shorted, then i would turn the board over and see if there is any cold solder joints or cracks in the solder connections if everything is still ok next then i would replace the convergence amp IC's
    this doesn't always fix it.
    heres some likes on how to replace them and i would replace both.

    theres only one it should be on a heat sink and it should be very large with three legs coming out also should be close to the flybak transformer red think wire connecting to the pic. tubes.
    you have to unsolder it and the check it with a multimeter, take one lag and put the meter on that one then check the other legs with the other meters probe do this for all three legs and then do it in the opposite direction using the reverse probe of the meter

The red power light comes on but nothing else works on my hitachi 53FDX01B PROJECTION TV


silly question but have you tried turning it on with the remote. if a tv has been turned off by remote and then power goes, turning it on by the tv switch will put the tv back in stand-by mode and you need to use remote.

just a suggestion.

Turn on tv and standby light flashes 6 times


The self-diagnostic function of the projection TV will cause the STANDBY light to blink or flash when the television detects an issue.

Follow the steps below to perform a power reset:
  1. Turn off the television.
  2. Unplug the TV power cord from the electrical outlet.
  3. Let the TV remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the TV is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the TV.
  5. Turn on the television. NOTE: If the TV does not turn on immediately, the fan may need to finish its cycle. This is part of the cooling process for some projection TVs and is normal operation. After the fan turns off, attempt to turn the TV on again.

If the issue is still unresolved after following all of the troubleshooting steps, service may be required . Please note the number of times the STANDBY light flashes and relay that information to the service center.

My panasonic rear projection tv will not power on and no lights turn on. Any suggestions?


Please plug TV in another power source and turn it ON,
if still does not turn ON, unplug AC wire of TV, take off back cover and follow AC cord f TV that will take you in power supply board, find fuse nearby and check is it blew off? if yes, replace it with same ratings written on it.
Plug TV in AC wall socket and turn ON, if fuse blow again that means power supply section in TV got problem and need qualified tech to find out and replace components or power board.
Thanks.
