Question about Hisense Televison & Video

Open Question

I have a 42" hisense tv. It keeps switching itself off within 2-4 seconds of turning it on. Just long enough to view a menu box. Is it fixable, and how do i fix it? Thank you for a feed back.

SOURCE: I have a 32" HD AKAI TV that keeps turning itself off

If the service shops didn't charge people $200 to fix this I would not post.. But since they do - here's the $8 fix.

If you are electronically inclined, replace the three 1000uf 16v electrolytic capacitors in the power supply board located above the power switch. They are likely bulging out at the top and failed. They are the three in a row at the top - center of the board, located between the two black heat sinks. Make sure you get caps rated for 105c degrees! I recommend replacing them with 1000uf 25v caps. 35v caps will work but might be a tight fit as they are larger diameter.

Should cost you about $8 for the parts shipped. You can get them from partsexpress or digikey or any good local electronics store. Your local radio shack may have them but they won'y be 105c and thus may not last long.

Not handy, ask around, there is usually some electronic tweaker guy around that will install them for a few bucks.

This has solved the turns on / then off problem every time in the 3 I've done.

SOURCE: Tv Turn sound on, No Picture, turns itself off within seconds

The TV is trying to go on protect mode because an internal fault had been detected. For that reson the protection circuit keeps turning off TV continuously.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

SOURCE: 42 in LG LCD TV turns off by itself

Found that TV started switching off by itself. Would try to come on..green light blinked for 2-3 seconds, tv came on (with picture and sound) for 1 or 2 seconds and then it would turn itself off. Found that the issue is with one channel only. If you are facing this issue....try quickly changing the channel the moment it comes on. You can do it either with remote or with the TV buttons directly. also in the same logic, if this is still happening, try changing the source to another (rgb-pc, av1, av2 etc). Basically change it from whatever input it is on currently, if changing the channels does not work. My symptom was that the tv made a loud 'TIK' 'TAK' sound which is louder than normal.

Losing sound momentarily


Are you using an HDMI cable and a digital box from your cable/sat company?

HDMI supports 2 different audio formats and when using a box from your provider sometimes the tv thinks the other format is available and switches to if for a few seconds.
Try using a HD component cable, they have Green, Blue, and Red video with Red and White audio, if the issue is your TV switching between formats this should fix it.

My Hisense lcd is lock.


This is how I got mine to work after weeks of struggling just trying to find a new remote (hisense is really hard to contact....).
1) Turn the TV ON. unplug the tv while still ON 2) hold down the "menu" button on the side of the TV and plug it back in. keep holding it down. the TV should turn on with the menu popping up. use the Vol <> keys and Channel <> keys to navigate the menu. go to the Vchip menu, and play around. I'm not sure what ultimately worked, but i changed the Vchip password to 1111, turned the reset menu to "on" and played around with the ratings settings (turning most of them to "u"s etc).
I went through this process several times and finally, the black background behind the menu turned to static. I played around with the channels, and the TV was unlocked. I turned the TV off, and then on again, and the channels showed up normally (no static). and it was no longer locked. I had to do the unplug thing several times, and was getting really frustrated looking for an "unlock code" in the manual (it just says press the button on the remote. so it was not really helpful).
But really, once you can just get to that menu you've made some progress, and just keep playing around with it until something works.
Best of luck!!

Hisense flat screen has locked


Try turning the main power switch on the back of the tv off.
Then hold the menu button and push that switch back on while still holding the menu button.
Keep holding the menu button until the setup menu pops up.
Next, be sure your input is set correctly(air or cable).
Next, do an auto channel search.

That did it for me. After I shut it off I had to do it one more time but it did the job. A friend of mine gave me the tv for free because nobody he new could figure it out. I took it home, got lucky, and figured it out in about ten minutes.

Hope this works for you. line-gry.gif
