Singer TV Model 20LNC

If you can't turn it on with the on button on the tv its not the remote causing issues. Are you able to pull the back off it and take some voltage measurement readings/

Look for loose contacts in power outlet. Try the TV on some other power outlet. There could also be a problem with the power cord.

Try manually pressing the power/standby button on the tv (side or bottom) the red light should appear, most modern tv's will turn on simply by pressing the channel up or down on the tv itself.. But unfortunately in most cases, this seems to be an internal surge and needs a professional to inspect..

Depending on the brand and MODEL number here is what I think happened.

All TV sets have a Standby power supply. It runs all the time even if set is off but plugged in.

It supplies among other things the power (usually less then 12 volts DC to run the remote circuitry---It usually is not fuse protected so if a strike hit nearby it may have come in via the power cord.

Trouble is almost certain to be in the standby supply.

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.

check the owner's manual, you'll see what the indicator light code means. More than likely it's your tv lamp.

standby light flashes tv wont turn on

yeah, should stay red when unit is turned off, indicating there's power but it's doing nothing.

Per user manual:
Solid red - power off (standby mode)
blinking red - power off (now cooling)
blinking green - power on (preparing to light lamp)
solid green - power on

Unplug the tv for 30 and plug back in.

If you dont hear a click theres a problem in the standby power supply. if you do hear a click theres a problem in the Main power supply or sweep supply. Get a good tech to look at this for you if your not a tech. Good Luck
