Question about Hitachi 55HDX99 55 in. Plasma HDTV

Open Question

Hitachi 55hdX99 shuts off and turns on by itself repeatedly

Once the TV is turned on either via remote or button on the TV, it is on for a few seconds then shuts off, then turns back on after a few seconds. It will continue this repeatedly until you shut it off again. Remote only activates volume or power. INput button works for a second then TV shuts off again, and on then off, etc... I think its the internal power supply but don't know for sure or where to start.

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

its most likely the common hitachi fault....its a little resistor that burns out, it happened mainly on the old crt tv's. any tv repair shop should be able to sort it for you.

Hello

Check the settings on your external devices,check the settings on the devices you are having a problem with. For example, if your Blu-Ray player is outputting to 1080p but your television supports a resolution of only 720p, this could cause the audio and the video to slip out of sync.

Try different inputs. If problems persist with external devices, plug them into different ports. The problem may be a bad input rather than a bad TV. Replace cables to make sure that isn't the problem.

Check the settings menu. If the image on your Hitachi TV looks too dark or too washed out, adjust the picture settings in the television's main menu. Sometimes the factory settings on a Hitachi TV aren't in line with the needs of the user

If this does not solve the problem,Press Menu Button, then in sequence 4, 7, 2 and 5.You are now in the Service Menu

Goto Options and press Factory Reset, it will only take a couple of seconds

Press Escape, Standby and Unplug from Mains Leave for 5 mins and turn all on again

If the problem persists, Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. They can be found online.

Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.

NOTE; If your tv is still under warranty,do not open the tv as this may void warranty.Best option will be to send the tv back to the dealer for replacement.

Trouble Finding Code


Have you tried the code search option:
Programming a Device using Code Search:

  1. Manually turn ON your device (TV, VCR, Cable Box)
  2. Press and "HOLD" CODE SEARCH
  3. Press and release the device button you want to set up (TV, VCR, Cable Box) However, if you are using AUX for a device, press and release AUX first and then the device button for the type of device to be programmed (TV, VCR, or Cable). The selected device button will flash once.
  4. Release CODE SEARCH.
  5. Press OFF/ON repeatedly until the device turns off (you may have to press up to 100 times at a rate of once per second).
  6. Once the device turns off, press and release ENTER.
  7. With the device on, press any other button. If the device responds, no further programming is required. If the device does not respond, repeat steps 1-6.
