If the tv is completely dead, your first step is to check the fuses in the power supply.but if you get the standby light, and nothing happens when you hit the power button, you need to call the repairman


good luck

Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Diagram for cooling fans that controls the lamp on a Hitachi TV


I have not seen this model Hitachi but I have never seen one with 2 fans for the lamp---in all cases there is usually only one-

Hitachi only offers service manuals online and only to authorized repair shops with a user name and password. If two fans ARE involved it is unlikely both would be bad---flying by the seat of our pants I would suggest if possible to check the voltage at the fans---or even spin them to see if they will suddenly work---dirt can cause a fan to slow or stop and the set would either shut down or issue some kind of "fan failure" or temperature warning.


I am willing to help as much as possible and I understand the desire for a diagram but that is unlikely.

Let me know if I can assist or such in any way---I do this here for free but am here to help people.

Hi, someone gave me a Hitachi 50VS69A TV and it doesn't turn on the lamp light flashes. But the power light doesn't even go on?


Have you since the lamp light is on even removed and inspected the lamp to see if shattered or not?

Hitachi L26D103. Less than 2 years old. Working fine one day. Turned on the next day and the sound works, but not the picture. This is an issue when in both the TV and DVD modes.


Good day!

If your TV doesn't have a picture even you play a DVD it means there is problem to your TV.It could be the Inverter board or the cold cathode lights is busted.


This are the steps on how to fix that problem.
  1. Remove the back cover of your TV.
  2. After that,plug in the TV and power it ON to perform a voltage data.
  3. Check the the output voltage of your power supply by using multimeter tester (range in DC) then check the 24vdc(supply of inverter board).
  4. If you have 24vdc in power supply output,check also the input voltage of inverter board if have 24vdc.If doesn't check the wire connection from power supply to the inverter board.
  5. If have you input voltage of inverter then check the high voltage output of it,if have at least 500vdc so be careful to check it because it have a high voltage.
  6. If doesn't have high voltage output replace the inverter board and if have a output voltage the cold cathode lamp inside is busted so you have to replace it
The inverter board looks like this:

    T.V. Loses its picture when it gets hot but I can still hear it


    Hitachi sets are prone to Power Supply Faults.

    I think your PSU is getting too hot, then shutting down.

    The better sets have Fans in them.

    Either repalce the Power Suplly or put up with the fan.

    It will however still fail in the end, one or more components are allready failing under stress / load.

    Thanks

    Cooling fan won't turn off.


    this set has more then one fan; one fan will run all the time to cool the digital circuit board---if it is the actual LAMP fan then you have a problem---the digital fan is very small and not located near the lamp.
