TV turns on, then immediately off again

Whether I use the remote or the button on the TV itself, it is only on for less then a second before switching itself back off again. The only troubleshooting suggestion in the owners manual that applied said to unplug it for an hour and try again. I left it unplugged for a day and tried, but still didn't work. I see another problem on here that might be the same, but the reply was way to technical for me. Can anyone offer any help, or should I just go get a new TV? my jvc tv power on and off. its just a second when i open the tv using button or remote its suddenly off and on again always on and off. how to fix this problem? when I turn the tv on, it turns itself off immediately try to turn tv on it turns on shows a blue screen then turns off after 2 seconds

Hi nel2874

so, you have a television that turns off immediately after you turn it on.
It sound like your power supply on the unit is out. Because I don't know the value of your unit I cannot comment on replacing the unit. But I would recommend that you use our website to find a Flat Panel TV Repairman near you. You may want to call to get an estimate on replacing the power supply before considering replacing the unit.

Why does TV turn off with the remote but won't stay off?


Greetings Charlotte,

All of the following assumes you are using the TV manufacturer provided remote ...
(ELSE: Get THAT remote, verify trouble & re-post fixya issue)

A few seconds is a really odd symptom (that's an IMMEDIATE cycle (2 power KEY HITS)... so before you rip into the electronic eye (Remote Recvr: tiny board at the control edge of your TV)... and/or change out the main power board...

(think... EVERYTHING else works remotely).

Try:
- unplug your set for at least ten minutes
- close the drapes (block sunlight from TV)
- find the receiver eye & remove ALL close obstructions
- check the remote & remove ALL covers/tape or soil.
- fresh batteries in the remote
- press power button as quickly as possible


Considering (I'm thinking)...

After MY studying HUMAN - MACHINE interface in a lifetime of trouble shooting... I came to know that when people become
VEXED by electronics... they tend to MASH buttons much-more deliberately (this can be a PROBLEM all by itself).

Critical timing on a button press used to be 500 to 900 milliseconds...

Meaning a longer press... went into special "handling" by program code (early software iteration (trial & errors).
((registered multiple KEY HITS = slower response, etc etc))

Your Remote Receiver is designed to register a continuous press (ON THE REMOTE) as ONE KEY HIT regardless of the DURATION... however

Any soil on the set (receiver) or remote (transmitter)...
visual objects, vases, mirrors... even sun-light can significantly change operation... as can TIRED BATTERIES (in the remote).

Failing all the cheap & easy suggestions above comment me back (+make & model) and I'll point you to procedures to get into your TV.

Hope this helps

Need code for my vizio tv i bought a ihip remote control for my tv


The instructions on letting the Hipi remote to seach for the code that came with my remote are not correct. I used the instructions from HOWTO.COM and printed below. There are two changes from the printed instructions. The first is to push the <TV> button after the <Code Search> button. The second is that the <Enter> button saved the code not the <MUTE> button.

Instructions
1
Turn on the Vizio TV.
2
Aim the Jumbo Universal Remote at the Vizio TV and hold down the "Code Search" button on the remove for roughly 3 to 5 seconds. The LED lights on the Jumbo Universal Remote will come on.
3
Press the "TV" button at the top of the Jumbo Universal Remote.
4
Start pressing the "ON/OFF" button repeatedly until the Vizio TV turns off. (This took only a few tries for my Vizio TV)
5
Press "Enter" on the remote immediately after the Vizio TV turns off to save the code.
6
Test the Jumbo Universal Remote by trying to control the Vizio TV with the remote. If the control doesn't work with the remote, repeat the entire process.

I was watching TV and suddenly the screen went black. No picture, no sound. On/off timer LED on TV started blinking. I could not turn it on (or off) with remote or ON switch on TV. I found that if I...


The television is shutting itself off to protect itself. The blinking light is a code pattern. The specific code determines whether or not you need an LCD Controller Unit, Main Board, power supply or something else. You would need the service manual. There are parts distributors you can get it from and the parts as well. If soldering and tv repair is not something you are entirely familiar you may want to seek a tv repair person. The manufacturer's support may walk you through the service menus to complete a factory reset depending upon the symptoms.

Polaroid TV Code


Hello,

About the only thing you can do is do a code search. If it doesn't show up then, the remote does not have it (as with most tv/dvd or tv/vcr combos).

Turn the TV on manually. Then, push the switch at the top to the far right (to the TV position). Simultaneously press and hold the MUTE and SELECT buttons until the TV light at the top flashes. Release the buttons, then press and release 9, 9, 1. The TV button should flash again.
Press and release the 1 button again, then press and release the TV POWER button. Press and release the Channel UP button about once a second until the TV turns itself off. Press and release the select button, and you should be good to go.

If after a while, the TV button starts flashing rapidly, then there are no more codes to search, and the remote does not have the code, and you are stuck using 2 remotes..

Hope this helps...
