It is most likely a 1000mF@25v capacitor in the power supply. Replacing this cap usually fixes the set.

1. Try this - hold the menu button down for 10 seconds. TV should power up; you will have to turn off front panel buttons on menu.

2. You can also try plugging in the TV through the USB on its panel to a computer or USB charger, and it may work. However, this is only a temporary solution.

3. Powering down the set or putting it in standby may have allowed the power supply to cool. Weak capacitors often go out of spec when they cool, thus preventing a section of the power supply from firing up properly again. There is a simple trick...just warm the back of the TV with a hair dryer for 5-7 mins after you have unplugged the TV. Look for the little areas of holes in the back panel of TV. Use these as your guide at where to use the hairdryer, but don't hold the dryer too close (say 5-6inches away). (Make sure the dryer is on High heat). If the TV doesn't turn on after you have heated it up (like it tries to come on but then turns off) you need to unplug the TV again, this resets it. And repeat those steps till it works. Resetting the TV after it fails to turn on is the key. Also, just leave the TV on. Don't turn in off. Since it is LCD, it doesn't take much power...only a few bucks extra a month for your utility bill.

4. A circuit board may crack about some of the larger components mounted on it. You can inspect the PCB's for fractures, and then repair them. It may also be poor soldering that has failed. I would be checking for these things first.


5. If you want to go in for a long term solution, you can easily replace the whole power board or just change the faulty capacitors. You will have to open the back panel and take a look. You can make out which are faulty, because their caps will be swollen on top. Here's a sample pic (not same model):
Power Will not function - d443bf7.jpg
Check the specifications of the faulty capacitors, and get the replacements from your local electronics shop. If you are comfortable with this, you can use a pair of needle nose pliers to G-E-N-T-L-Y pull out the defunct capacitors. Once that is done, solder in the new capacitors carefully. If are unsure how to do this, try to get a friend who knows how to do this kinda stuff do it for you, or get a qualified technician. Warning: If you do not have a background in electronics repair, or are inexperienced, get a qualified technician to do it for you.

REMEMBER there are very dangerous voltages inside a TV that can KILL. Be sure to work SAFE when dealing with electricity. DISCONNECT THE POWER BEFORE YOU DO ANYTHING.

Hope that helps...Should you have any further questions, please feel free to post them here.

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 sony grand wega kdf e55a20 power light keeps blinking red. what can the problem be?


Red is an indication signal for power connectivity. Recent devices have two power functionalities. Using the remote control would turn off the display of images to power saver mode. A red power light imiting diode display is indication that requiring display of images is achievable by pressing on the display mode button once more. NOTES; Powering on the device may be achieved with the same function buttons as shutting down the entire Device to least communicate with the power supply circuity from outlet sources. The device is in power off mode ready for repower on with the remote control. Requesting the TV to shut down completely would require to press on the TV button firmly until power cuicuit are disbabled completely. Refer to the TV user guide to ascertain fucntionaility modes usual during operations. Goodluck

I bought my son a 19" philips tv model # 19pfl340d/27.in order to turn tv on it must be unplugged for 10-15 minutes.The first one I bought did the same thing and I returned it.this one is exactly the...


The remote control will not operate the TV when the TV is in the OFF mode (No LED lit on front bezel). To change the mode from OFF to STANDBY or ON, press the POWER button on the side of the TV. Once the POWER button is pressed, the LED will change to either red to indicate STANDBY or green to indicate ON, whichever mode the TV was in prior to being turned off with the TV POWER button.

By pressing the POWER button on the side of the TV, the mode will toggle from OFF to either STANDBY or ON. If the POWER button is pressed and then the LED on the bezel is red, the TV is in STANDBY mode and will need to be turned on using the remote control. If the POWER button is pressed and then the LED on the bezel is green, the TV is ON.
