Question about Hitachi P50H401 50 in. Plasma HDTV

2 Answers

All of a sudden my Hitachi P50H401 has not been turning on. I simply plug it into an outlet and it turns on for 2 seconds then immediately shuts down (not even the red standby light stays on) . Any explanation or solution would be awesome. Thanks

These tv's are know to have some issues. Some of the caps in the power supply are known to go bad. Normaly its the two 3300uf 100v 105c caps by the output that goes into the xsus board. But its good to open the set and check for other swollen caps.

You say the standby light doesn't come on or anything. Normally these sets are known for the light on the front of them to start flashing when something is wrong. So i am thinking it is something with the power supply.

Hitachi p50h401 wont turn on no power at all


This problem is mainly on the fuse or in the power supply. Just check first the power chord if they are plug properly to the outlet and to the TV...
If they are properly place but still no picture. It's time for you to call or bring your TV to the nearest repair center for them to fix the trouble

Hello williams6590,

Welcome, and thank you for using FixYa!

Your problem is the X-Sustain Board. There are a large number of componants and connections on this board. I recommend purchasing it from eBay! and then having a TV Repair Professional install it.

Here is a link to purchase the part:

I have a hitachi 50 "plasma that was given to me


First do you see a light indicating that the TV has power? There are two power buttons on the TV (the main power and the regular power button). The red standby light will light up when the main power switch is on. This indicator is just to the left of the remote I/R sensor. You can find the main switch on the bottom front of the tv (it is under the tv forward of the stand). Turn on the Main power if it is not on. Then try the power button on the control panel of the TV again.

Does the standby light change color or blink? (Red is standby, orange is power savings (no signal), blue is on.) If the main switch is on and the standby light doesn't come on, the TV has a problem at the power supply. Try unplugging the unit for a bit (at least 30 seconds) and then plugging it back in. This will reset the internal circuitry. If you see a blinking light, then the TV is reporting a self-test failure. I do not know the codes for this model Hitachi Plasma TV.

The manual for the Hitachi P50H401 TV is available from Retrevo: http://www.retrevo.com/support/Hitachi-P50H401-TVs-manual/id/1233ci869/t/2/ . You will need to enter a code to access the pdf.

I'm assuming you don't have one of the special versions that were intended for large audiences that were only controlled by remote (no control keys on the front of the TV). Remotes.com has the original remote or a substitute remote if you need it. See http://www.remotes.com/remotes/servlet/rs?a=gmi&uuid=13104063628240&smodel=P50H401&brand_pn=HITACHI_P50H401 .

I hope this helps.

My hitachi will not power on when clicking the power button it comes on for a second or less and immediately clicks off


I have worked on a lot of these sets and in fact own one almost identical to yours. The shut off means either a "shut down" circuit is being engaged because of a problem somewhere in the set OR you may have the same problem mine had---here is what I did.

I plugged the set into a outlet controlled by a wall switch: turn set on and it shuts off, turn wall switch off for a second and back on and try turn set on.

In my case sometimes had to do this many times but eventually the set would come on. In my case problem turned out to be bad capacitor near the main power relay, that is the click you hear when try turn set on----if it will not come on after say 20 tries it is bad part most likely in power supply or even bad solder connections that develop after age in many set.

Let me know what you find and IF ANY QUESTIONS feel free to comment here and the site will email me so I can assist you.

Hello, I have a p50h401a and the red standby light is flashing. i can power the tv up and it works for about three seconds and then it shuts down, back to the flashing red light. I was wondering if this is...


A lot of modern day tv;s have power supply failures due to capacitors drying out , you can sometime tell which ones are faulty if they swell up or deform. if so they need replaced. Not a hard job for some one who is experienced,

Hitachi Plasma TV model P50H401


I think you have problems with the digital main PWB.

If the power PWB failed, turn off and change the pilot ligth to red.
