Why wont my hitachi remote RC1205 work on my TV, I've changed the batteries

Either the remote is fubar or the receiving circuits on tv are fubar. There is a way of checking a remote with a digital camera. - Google it and see what the story is.

When battery is changed, all the previous settings will be lost from the remote control. You should once again set it to your device, using codes.

Visit the site named 'Electro-help' for more details. Click this link. View it in "Timeslide" or "Flipcard" option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. You can also click the [Home] tab to see the latest updates. It will make search easy. There are more than 1350 posts to different brand TVs now. Pull up older posts there or do a search by type in the Brand Name of your device in the Search Box, at the top right of the display window.

I have suggestion for you please scan your external hard disk with a good antivirus and then anti malware bytes. Possible your problem will be solved. Thank you so much....

Hello
First check its battery contacts for any rust or dirt accumulated on it. If so, contacts of battery will not touch properly, and the unit will fail to work. The second reason for malfunction is due to the infrared sensor inside your tV. If it is faulty, the set won't respond to infrared signal generated by the remote control. If so, eventhough remote control works properly, the set won't work with it.
Remote sensor comes just behind the infrared window at the bottom front panel of your TV. It is a replacable part and not so costly too. It is a three terninal component will look brownish black in colour. It will looke like this.

The procedure to check the remote control for its perfect working is described at a tip I've given and published by Fixya on Google. Type "gopakumarg43" on google search box, and get into my profiles. There you can see 'Tips and How To's" line, click on it. You can read it there. OK.

Check for rusted battery contacts due to leaked batteries. Clean them with polish paper or blade. Due to leaked batteries it is quite likely that the wires connecting remote control pcb & battery contacts are cut off.

If the tv was on when you unhooked it there is a cooling fan that didn't get to cool off the picture box and it has overheated and you will have to replace the box you can order it off of eBay it takes a few moments to replace it if you still have your owners manual it will tell you all about the lights on the front of your tv I've had to change mine out a few times hope this helps Merry Christmas

1st step, replace battery of remote, no result, 2nd step, check / replace Remote Sensor of TV.
