TV control do not respond when operated manually or via the remote

The TV switches On and Off manually, picture obtained. Unable to make any adjustment ie change channel, adjust the volume using the remote or by using the manual buttons on the TV. I have eliminated the remote control in that new batteries have been installed. I get the same behaviour from the TV with the batteries removed from the remote. Apart from identifying any dry joints on a circuit board I would appreciate advice on any further trouble shooting and possible part replacement and cost to repair via TV technician against cost to replace with new. Many Thanks

    I've solved my own problem to update the TV is a Samsung LE26B450C4W. In addition to the symptoms listed the TV channel kept repeatedly changing down which I dictated a possible issue with the buttons at the side of the TV. I was able to disconnect and remove the buttons and it's associated pcb. The TV now behaves and can be stated with the remote control.

SOURCE: TV won't change channels or adjust volume

Do you have a universal remote? If the batteries are taken out for a little period of time, the remote will loose the codes and they will have to be reset. You can find the codes by google universal remote codes.

If you have a factory remote that came with the television, than it may be faulty or the sensor on remote or tv may need to be cleaned.

SOURCE: TV does not respond to

When this kind of a problem appears it is usually due to a malfunctioning microprocessor IC . The IC cannot be replaced and the board has to be replaced as a whole. Replacement board should run you about 100$. I can find you a replacement if you are interested in fixing it.

013/ 054/ 055/ 060/ 065/ 067/ 089 These are the three digit codes to Jvc brand TVs. As there is no remote control with you, the first thing to know is, to which code do your TV respond. Some TVs will respond to three digit codes, some others will only respond to four or five digit codes. If your TV do respond to three digit codes, a universal remote control, which have the above said codes in its code list will work. If you wish to get three, four & five digit code list to some popular remote controls, check the links given above. You can choose the proper remote control to your TV. But before buying a new remote control, make sure about the number of digits of codes that TV must have.

My Toshiba 2939DB needs to be tuned in to pick up SKY. I cannot tune the TV as I do not have the original remote control - any tips?

There are many companies on the net that make generic remote controls for TV,VCR etc and it may be possible to obtain an original. If you Google "Replacement remote controls" then I'm sure you'll find one. Don't be tempted by these cheap remotes where you get a code book with them, many of them will NOT operate certain functions of the TV, including tuning. Beware!
Your problem seems to be that you want to tune the Sky box into the TV via the RF output of the box. Why not connect it by scart socket? You'll get a much better picture and if your set is nicam, stereo sound too.
I wish you luck!

TV -Ferguson (Wide Screen) model no: W7023U. unable to operate either with remote control or manually.

Is it possible it has locked itself? It can be locked in 3 ways according to manual.

1. by pressing the remote's stand by key for more than 3 secs.

2. By programming an auto stop.

3. By putting it on stand by after programming a wake-up time.

Flashing "red on" indicates it is locked. It can only be turned on by the remote. Press any number key on the remote to unlock it.
