Have TV Questions? Ask a TV Technician
Hi , I`m JackPerhaps I can help you with this problem but first could you please send me a reply when you see this ?
Sorry but I was out by the time you replied to me last night.
There could actually be a simple reason why it all stop working at one (remote and tactiles) , if the pad at the front went defective then it can very well affect the remote sensor , a bit like a stuck button will cut all communication to the main board .
Or the reverse is also true , a defective sensor could cut-off the p-touch buttons
And finally the main board itself could be processing video and audio just fine but its system control part be unresponsive .
Right now I give this a much higher chance that the tactiles /p-touch buttons at the front have gone defective.
At this point there would be some troubleshooting to be done with the back cover removed .
Let me know and i will help you along if you wish to look into repairing this yourself ,otherwise i will give you the details and costs you could expect.
