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.

Hitachi p50h401 the power light keeps flashing


If you have a flashing red light, try this first: The flashing red light is, according to the Hitachi service manual, an indication of exactly one problem. It is that the fan (internal, blows air over the power supply heat sinks) has failed. In my case, it failed by continuing to spin (very confusing), but put out a signal (3V on the white wire of the fan harness) that it has failed (I had to look up the data sheet on the fan to figure this out). A new fan from Arrow $10 fixed the problem. If you suspect your fan, spinning or not, you can safely short the white to the black wire to see if your TV remains on after being turned on (solid red light), and then try turning your TV on (blue light) to see if it works.

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:

My 42HDS69 Hitachi has a recurring problem of not turning on. I unplug from outlet for awhile and sometimes it will turn after I plug in outlet, Other times it takes a few hours for TV to turn back on. ...


MY TV KEPT GETTING WORSE EACH DAY ALSO. BUY A CAN OF SPRAY AIR WITH THE EXTENSION SPRAY TUBE. WHEN YOU GET THE TV RUNNING SPRAY THROUGH THE HOLES IN THE BACK RIGHT ONTO THE FAN BLADES OF BOTH FANS. THE DUST WILL FLY OFF THE BLADES. A VACUMM HOSE WILL HELP PULL OUT THE DUST. ALSO SRAY THE POWER SUPPLY BOARD FOR DUST. I APPEARS THE FANS SLOW DOWN WITH DIRT ON THEM AND THE EXTRA HEAT BUILD UP JUST AFTER THE TV IS SHUT DOWN IS CAUSING THE POWER SUPPLY TO BE IN A SHUT DOWN MODE WHEN POWERED UP THE NEXT TIME. BEEN TWO WEEKS NOW AND WORKS PERFECTLY NOW AGAIN.

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.
