Question about Hitachi 42HDT51 42 in. Plasma SLC1551AW

1 Answer

No power My problem is that the t.v. is not getting power. The outlet on the wall works fine. I even plugged the power cord into the AVC and it powered that up. Does the t.v. have some sort of reset button on it?

Re: no power

There is no reset on this TV. The SMPS (switch mode power supply) has been a problem on some of these models. There are no components available for this board as it has to be replaced as an entire assembly. If one or more of the fuses on the SMPS board have opened up then you might have a bad scan or sustain board. A qualified technician will be able to diagnose which board is loading the power supply if this is the case. Good luck to you. Joe Weibel

Sharp Aquos LC45GX6U & TU-GD10U. The unit doesn't power up, and has a red blinking light from the moment you plug it in. The unit works fine in service mode.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

My set is plugged into a cable box. the tv will not turn on either manually or with the remote.

Plug the power cord directly into a wall power outlet, and make sure that the standby light is lit (turn it on/off manually to see if anything changes). If there isn't any light, then it's most likely broken.
If the TV works again, being plugged into the power outlet in the wall, then the problem is with the cable box (i bet you figured that out too).

Tv turns off and on over and over

Hello, This may seem kinda silly but please check that the power cord is fully seated into the tv's power socket. Just remove the power cord from the TV, and re-insert it back in. Also verify that the other end is fully seated into the wall outlet or extension cord!
Good Luck

Tv come with no sound or pict.

Check whether the product is turned on.
Try another channel. The problem may be with the broadcast.
Is the power cord inserted into wall power outlet?
Check your antenna direction and/or location.
Test the wall power outlet, plug another product's power cord into the outlet where the product's power cord was plugged in.
If these tips don't work, you can also try to power cycle the TV. Turn the TV off and unplug it for about a minute. Plug it back in and power it back on to reset the settings back to factory default.

I have no power to my VCR? Was working fine

It could be a fuse to the outlet that it is plugged into. It could be what the VCR is plugged into.
In many homes and apartments there is a light switch on the wall that may control the lower wall plug in a pair. The best way to find out, is to remove the VCR and plug it into an outlet that you are totally certain works. i.e. test the outlet with a table lamp.
Then after you test it, you will then be certain it is the VCR. Most of the time in diagnosing problems such as "DOESN'T WORK AT ALL", i.e. a massive failure. It is due to problems in the power source.

Rarely an uninvited animal guest chews through the wire in the wall. Sometimes it just needs a new
plug installed on the end of the cord.

If it is the VCR, Check inside of it for a fuse.

Covers can be removed using a Phillips head screwdriver. Either a #1 or a #2 sized driver blade.
Screws will be on the side or rear of the unit. When removing the cover lift from the rear for most
Hope this helps,

Tv does not power up, checked plug, fuse and power lead that is fine, switched tv on off several times still nothing! plz help...........

There are probably a few capacitors on the power board that have defective formula and will need replacing. If you have some basic test equipment and a basic electronics background I can walk you through some troubleshooting steps. Otherwise if its still under warranty take it back, if not you can consult your local TV repair technician. CLICK HERE to find TV technicians in your area just enter your zip code.
And of course always check the basics first by making sure the wall outlet that the TV is plugged into is working. Check the ac cord, make sure its fully connected to both the wall outlet and the TV ....etc

TV randomly turns itself off and on

This issue is related to the TV's main board not seeing constant A/C power to unit so the board is turning off the TV.

When the TV's main board see A/C power back to the unit, the TV will try to turn back on.

This issue could be a loose power connection for the TV or a failing part inside the TV. Do other electrical devices work when plugged into the same wall outlet?

Try the following:
1. Remove the cord from the back of the TV and reinstall it (perhaps it's loose going into the TV and was not installed correctly).
2. Try putting the cord into a different wall outlet (perhaps it's not a good outlet).
3. Try using a new power cord for the TV. (Any matching cord will work for testing)

If the above did not resolve the issue, then it could be the switch mode power supply and or the main board inside the TV. Both items are easy to change out.

I can look up the LG part number for you.

My TV will play fine for 10-20 min. after that the screen will go blank.I have no problems with the sound.When I unplug the power cord for a few min. and plug it back in the TV works


Please remove the power cord of the TV, if it is connected to any power surge box and connect it directly to wall jack or wall outlet. Do not place any magnetic items nearby the TV. Do not completely cover the LCD with plastic cover or cloth.

This should resolve the issue.

I have no power or picture on my view sonic television ...what could be the problem

It's most likely a capacitor. Open up your television, and look at your power circuit board. Look to see if any of the capacitors are blown.(the will be bulging look up an image of a blown capacitor to get a better image if not known already. Mine was (CS19, CS21, CS22, CS23) Also on (C672) from the Circuit Board.Can you look at the voltages of these for me? I'm missing the capacitors.
