[SOLVED] TV doesn't responding to the remote

[--BawA--]

My TV is not responding to the remote , i tried to check the remote with camera , its fine , I also replaced the old remote with new one ,but still it's not working , I thing there is some problem in reciever section of the television
2 or 3 days ago , the reciever was working partially , i mean some time the tv was responding to remote n sometimes did not, but today its totally not working, what could be the possible fault in the tv?

 

[FvM]

Defective RC receiver IC, defective power supply causing strong RC receiver supply voltage ripple.

Strong optical interferences from LED or FL with high switched mode supply might be also a reason.

thanx FvM ,
As my TV is too old (15 years) so i think there might be a problem in supply , as electrolytic capacitors have certain life , so due to some faulty caps , there will be a huge ripple on the supply voltage of reciever, isn't it?

Power supply should be definitely checked.

ok FvM, I'll open the TV set tomorrow, and will analyse the power supply section.
