Bad remote.

retight the springs contacts batteries, for better contacts. and try again.

tried with reset doesn't work, ok it could be the IR sensor at the front panel of the tv doesn't work. but before you replace it you need to ensure if your remote controller is working. have you tried to check the remote with camera trick just to know if the remote controller is sending light to the IR sensor of the tv.

1) the batteries will be the same type and full charged
2) clean the contacts battery from dirty, dust, oxide or corrosion
3) retight the spring contacts battery with pliers for a GOOD contacts
4) open the remote.control and clean the keypads switch, from dirty, dust, oxide, Open contacts, or Bad contacts. they emite a good signal infrared from SYScon transmi vs Syscon receiver.
see the block diagram. If doesnot resolve the problem go to the repair shop TV for fix it.

Check the infrared emission from the remote control first. If it is found OK, repalce the infrared sensor inside your tV.

Hi.

Please test the TV using a programmable remote. If the TV works using the programmable remote buy a replacement remote control:

NEW POLAROID REMOTE CONTROL TDA-03211C TDX-01930B

Polaroid TDX01930B Replacement Remote Control

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.

Hi,
To confirmed if the remote control is working fine, aim the remote control sensor(IR emitter) directly to your cellphone camera. While pressing any button key on the remote control, you can see the flash of an infrared emitted by the remote control if it is working fine.


If you've confirmed that the remote control emitted an infrared but still the tv won't communicate with it, this is an indication of faulty IR sensor board of the TV. Check if there's an obstruction from the IR receiver in front. Keep away all of it, clean the plastic window of the IR receiver with soft clean cloth.
If the symptoms still persist, you have to replace the IR sensor board. Check the actual part no. of the board before ordering.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

HERE'S THE ANSWER TO YOUR PROBLEM:

The possible reason why your TV doesn't respond to your remote is probably the battery of your remote. Maybe it has been used up to it's fullest capacity, so try checking it up. In case, it has been used up, try to buy a new one.

The possible reason why your TV doesn't stay on is still your remote control. Maybe you have accidentally set it to "sleep mode." When it is set into sleep mode, it turns on just for a shorter time. It cannot stay on longer.

So, here's what you've got to do. Check your remote. When the remote works already, press the sleep button remote again. I hope it works for you.

Thanks.
