I OWN A RELISYS PLASMA TV 42" WHICH I BOUGHT 6 YEARS AGO AND THE REMOTE CONTROL IS NOT RESPONDING ANYMORE. i HAVE TRIED SOME UNIVERSAL REMOTE CONTROLS WITH NO LUCK. tHE PROBLEM IS THAT I DO NOT KNOW THE EXACT MODEL. ALL I HAVE IS A NUMBER AT THE BACK OF THE MANUAL THAT SAYS "4U420B05". hOW CAN I GET A NEW REMOTE?
tHANK YOU IN ADVANCE.
