Question about Toshiba 42H81 42" Rear Projection Television

1 Answer

Remote control will not work

The Remote is sending the signal, but the TV is not reading. Maybe the Sensor went bad

    The TV works but the remote wont work it.  The remote has new batteries and will light up.  My Toshiba has a split screen that I dearly love but I can only access it with the remote.  Since the remote lights up, I wonder about what reads it in the TV.  My Toshiba is a 42H83 42 inch.

I have a e422vle Vizio TV. The power board went bad, I ordered a new one and the Tv now is working but the remote doesn't work. Is the remote sensor on the power board?


Check the remote control for its infra-red emission. Check it with fresh batteries. Check by pressing all the buttons on it; and see whether all of it generates infrared signal while pressing. If it is found OK, check and replace the infrared sensor inside the TV. If you wish to get some details; check the site linked here. It has details about how to check a remote control; by one among the post. Pull up older posts. If the remote control is found OK; check and replace the infra-red sensor inside the TV.

It reads TEST in the display screen and will not change


follow this steps and fix it. God bless you

Either the remote or the receptor on the device is not functioning.
Use an Intraed Sensor to see if the remote is sending a signal.
If the remote is sending a signal, it used to control that device, and no other solution works, you should have a service center look at the device and remote to determine the problem and if it can be fixed.
If the remote is not sending a signal and you have replaced the batteries, you will need to repair or replace the remote, depending on cost.

My samsung led remote control has just stopped working and i can't get it to work again. I've changed the batteries and i cannot find the reset button. I've unplugged the power from the wall and still no...


We need to find out first if the remote is putting out the IR signals or not, or the problem is in the TV IR receiver module.
Testing remote control:
The remote control puts out IR (InfraRed) signal that human eyes cannot see, to find out if the remote is sending out the signal or not you just point the remote at the digital camera's Lens (Digital Camera can detect IR), you should see flashing light on the camera's screen when any one of the remote button is pushed. If you do see the flashing on the camera, then the problem is in the TV IR receiver or the main logic board; more troubleshooting with scope will be needed to look at the signals.

Hello,

If new batteries did not fix the problem, then it means the problem is either from the remote or the TV.

Remote: Check the remote battery terminal, see if its not rust. Also, disassemble the remote, can check the connection between the terminal and the remote board, see if there is no disconnection of any kind.

If after checking and all seems well, then it means the remote is defective. To confirm, borrow a remote, test it with the TV. If it works, then it means you need to replace your remote. But if the remote you borrowed does not work, then it means the problem is from the TV and not the remote.

TV: There is a sensor in the TV that communicates with the remote. If this sensor is defective, the remote won't communicate with the TV.

The TV sensor might have loosed contact from inside of the TV or it maybe defective and need to be replaced.

So do the above troubleshooting and let me know if the problem is from the TV or remote. If problem is from the remote, you need to do a replacement. But if otherwise, let me knows as well.

Good luck.

Remote control No work


Try another remote control, if it is also not working that means remote sensor in tv got bad and become unable to receive remote signals, replace remote sensor in tv.
If other remote works then replace batteries in bad/ suspected remote and check.
Let me know model and brand of your tv if you have additional question.
Thanks.

It can be the IR receiver board is bad, or the remote is not send out the IR signal.

Also look at the back of the TV to see if it has IR input jack, if it does, then the switch inside the jack may have to be cleaned.

My remote control does not work


You could have a defective IR sensor in the tv set that sends the infared signal to the MIcroprocessor IC. These are something you cant just replace, as it needs to be trouble shot with a scope to see if theres a data signal comming out of the sensor and if there is it could be a bad solder connection somewhere between the sensor plug to the Main IC. Also could be the B+ that supplys voltage to the sensor. Unless you have had electronic repoair experience, You should have a pro assist you with this repair. Sorry I couldnt assist you more with this . Good Luck
