I hate to say this but you are looking at a repair cost to get this going again. You may have some luck leaving the unit unplugged for a few weeks and then re trying it but that is a long shot. If it were my unit I would recycle the old one and replace with a used or new unit. If the problem is power supply related repair charges can be in the 40-60 dollar range. Decide on your own what is best for you but the unit will need repair by a shop technician most likely.

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

Magnavox 37MF23ID, would not turn on. Power button only blinks (green light). We have switched power cords and nothing happens. No picture, no sound.


if the power light comes on but the screen stays black, then your TV might be on the wrong input Channel. for example: you switch inputs when you play games or watch dvds vs. watching regular tv. Try to change the input

Why suddenly my remote control cannot Control tv . It can before , but now cannot


Check to see if the infrared led is working. Here's how to test, using your cell phone camera, point remote to the camera (cell camera must be on) then press any button in remote, on the cell phone camera, you will view a white light, if no white light comes on while you pressing the remote buttons, then the infrared led has died our, needs to be replaced. Alternatively check batteries are OK, make sure there is contact with connectors inside battery bay

Buttons on TV suddenly not responsive


If they are actual buttons check to see if one is stuck. Listen for a click on each button while it is turned off so you can hear it and feel it. Another possibility could be when you moved it around somehow the internal cable that connects the buttons to a connector has slipped out or just has a bad connection. Would require you to take the bezel off to see if the internal connections are ok. Not sure what else to suggest. At least the remote works.

Non responsive buttons


You have to open up the remote. The underside of each button has a black disk. Clean each button with a pencil eraser. Then look at the circuit board. Where each of the black discs would make contact (looks like two "E"s facing each other) clean each of those with the eraser. But the remote back together and all the buttons will be responsive.

No response to any button on remote or tv except power button


Press the 'Favorite' button on the remote. You may have accidentally pressed it. It locks the channel. Pressing again unlocks.

My Sharp Remote Control Is Suddenly Stop Working


Ok I just dealt with the Sharp customer support for this problem.

1) You need to unplug the TV for 1 full minute and remove the batteries from your remote aswell (this will reset the system)
2) Hold the power button on the remote for 30 seconds with the batteries still out of the remote and the TV still unplugged
3) After the 30 seconds replace batteries then press every button on the remote beginning with the power button in order from left to right and top to bottom (same way you read)
4) Then plug your tv back in and try the remote again.... and the remote and TV should be back in sync.

MY ASTAR TV screenshows vertical color bands and its non responsive


If you still have the TV, the remote has to be re-set. Hold the Enter button down approximately 10-seconds. It should re-set itself.
