Feels like I have all new TVs. Just gently pry the remotes open (I used a hard, durable stainless steel scraper and a medium flathead screwdriver to pry the plastic), then rub the circuit board with 70% alcohol (didn't rub the buttons), cut the toothpick in half halves . and sanded smooth and even, then applying as little of this carbon compound as possible to each button while still completely covering the point of contact of each button. Even that was too difficult; and I had to partially reassemble, double click on all the buttons, then disassemble and just wipe the PCB contact pads again. The first remote required 4 or 5 reassemblies to remove excess carbon (no wiping the rubber button contacts, just the PCB contacts), subsequent remotes still required 3 reassemblies and wiping to ensure no button was activated by excess carbon grease the entire time. . I did all five "bad" remotes in 3 hours, distracted by watching football on TV at the same time. Very happy! Now I can always fix my volume, channel, enter and back buttons if they stop working properly, which is typically 12 to 18 months between remote failures on my Sony and Samsung. (I have a Pioneer Theater remote that hasn't let me down once in 8 years, find out.)
