Remote IR Reciever Problem

I have the OEM and an aftermarket remote. When I turn the volume down using either remote the tv will set a timer to turn off. When I turn the volume up, sometimes the tv will show the menu or mute. Changing channels is just as interesting. Also, sometimes the remote works with a flaw. Any ideas what could be causing the random button assignment?

Turn off fpa lock without remote

Install an IR Remote App in android phone. The app link below worked for me to remove the fpa lock on. Configure the App for your RCA TV. Set TV as Device type, RCA as the brand. and choose the model (e.g., TV 20 F420T) also, select the Alternate IR Driver.

All the options of the command may appear in a list form. Close that and an actual remote with buttons should appear.

Then Power your tv will turn ON. Press the Menu. Pressing the Channel Down/Up Button to navigate to Preferences. Press OK button on the screen.. Then Navigate to FPA Lock. Press OK again. THis will turn the FPA Lock to Off.

Then you could use your on-TV buttons ZappIR Universal IR Remote Android Apps on Google Play

Since changing to freeview in april i no longer need the use of the original tv remote as the new remote is being used. my problem now is i cant find how to set the tv to sleep mode shud i fall asleep...

Your new FreeView remote will only support the essential functions of your tv. In some cases that's limited to volume up and down, sound mute and on/off only, but often they can do more. Sleep timers are rarely supported.

Your fix is to either set the sleep timer on the old remote, or to buy another fully programmable learning remote control, where you can customise almost every button and use your old remote to teach the learning version its tricks.

Bought a used Toshiba model# 32A33 tv with vchip code set. Cannot reset. How can I reset vchip code?

Hold down the Vol - key on the TV. When Volume is at the minimum, hold down the 0 button on the remote. Remain holding both keys for at least 1 full second. Be sure your arm or hand is not obstructing the remote IR beam to the TVs IR receiver.

Toshiba CF32H50-no control from remote

Could be the remote does not operate on the correct frequency, but also may be the IR reciever sensor inside the TV, best bet is to bring your remote to a pawn shop and try it on a set there (they sell older model sets look till you find one like yours). once you determine the remote is OK, check the IR sensor for bad solder connection or replace it by soldering a new one in. Also some Toshibas develop micro CPU issue (the computer IC), another thing you can try is cleaning the main board control area with electrical cleaner residue can load down the control circuits but then the buttons would also malfunction.

Toshiba TV Remote Control not working

Remote no longer works

In side of the TV set there is a remote receiver module. In some models of sets, there is no module. They use descrete components on the main circuit board. The fault could be in the remote receiver section. In some models of TV sets there are some remote amplifiation circuits along the way to the uPC controler. There could be a fault along this path.

The service tech would troubleshoot this by verifying the voltage supply to the remote receiver circuits. Then he would shoot an IR remote signal to the receiver, and then follow the data flow from the output of the IR reciever circuits along its signal path to the uPC controler. This way, he should be able to see with the scope where the data signal is failing.

1934 model recieving


The IR detector is in your TV set. It is the device that picks up or captures the IR signal from your remote control and turns it into an electrical signal that the TV via a processor interprets as a function or command to have the TV perform in a certain way as turning on, channel up or down, volume up or down, etc.

IR means Infrared

I hope this answers your question.

Thank you,

TV Remote control

The IR reciever should be in the front of the set where the remote IR window is located.

I can tell you that there is a lot more that can go wrong than just the IR reciever. There may be a buffer amp along the way to the uPC, or there may be a fault with the uPC itself. The fault may also be a cold solder connection, or a missing supply voltage to the the IR reciever or to some of the components involved in the IR signal process.

In opening and working on your set, there are serious safety issues involved. You should be giving the set out to a trained and experienced TV tech for proper and reliable service.

TV won't respond to remote(s)

I don't know of any adjustments for the IR receiver but the receiver itself could have gone bad or something may be blocking the IR lens not letting the IR signal get through. Maybe (but unusual) there may be a cold solder joint in the IR circuit. Sometimes dust will collect on the inside of the IR lens causing this problem. You can verify the operation of your remotes by holding them close to an AM radio receiver and pushing the buttons. You'll hear a popping sound through the radio speaker whenever a button is pushed. You may have to tune the radio up or down the band to pick up the remote's signal. Stargazer
