content: Hi everyone all of a sudden my Samsung remote TV button starts flashing and the volume goes to 100 I have tried all the fixes that I read but I do think my remote is faultyWith the tv off and I press any button the Remote TV button flashs very quickly and only stops briefly if i press any button but starts again as soon as i stop pressing any buttons and as said with the tv on as soon as i push any button on the remote the volume goes up to 100 and only stops briefly if i press any remote button . Without touching the remote the TV works ok with the TV buttons and I do have another samsung remote and it works ok with the TV. Alot of answers were to do a reset and if I had a Apple or firestick remote to take the batteries out but none of these work I really believe the remote is faulty or can anyone come up with a solution to solve this or fix the remote. Thanks for any help, Nics

content: So you've tried cleaning the button side? Often moisture builds up under the keys. Clean the board and pads under each button gently with iso alcohol on paper towel or Q-tip. It's just carbon and will wipe off if you press too hard.

content: Thanks Jonny yep have done all that and put together loosely but as as soon as I touch any button the the tv button on remote goes into a rapid flashing mode and only stops if i press any button but it contiunes as soon as I release the button this is even with TV off, the only buttons that doesn't stop it is the red power button and the volume up button and if i press the reset button it stops it completly but again touch any button it starts flashing again.

content: Agree that it sounds like the volume up button is "stuck" on.Not sure how the batteries are connected, but can you operate it with the PCB removed from the housing, or else reassembly it in the housing but with the rubber buttons removed.Use a small metal object to activate the buttons, e.g. a small piece of rolled up aluminium foil.If it operates normally like this, then the fault is likely to be on the rubber button contact side. If it still has a problem, then it is a fault on the PCB.

content: Hi Kean did what you said was able to remove buttons and batteries connected and with no remote buttons connected and a single push with single rubber button and nothing else touching its still flashing so at moment looking like faulty remote is there any thing on the remote that can be changed [picture u1, u2,y1 c1] with little cost,or just buy a new remote.

content: OK, I would try cleaning the PCB - ideally with isopropyl alcohol and maybe an old toothbrush - as there appears to be some flux residue which could become slightly conductive over time. There may also be other contaminants that are harder to see around the button contacts or IC pins.If you don't have isopropyl alcohol, then you can clean it with warm soapy water and a brush, and then rinse it well ideally with distilled or deionised water. You will need to then leave it somewhere warm for a couple of days to completely dry.Replacement remote controls are usually pretty easy to find, and quite low cost.

content: Success, Thank you Kean thats what it was and apologizes to Jonny and MK14 they did mention to clean which I did with cotton buds but I had to clean the whole board and buttons a good hard scrubbing with isopropyl alcohol and using brush. Thanks again to everyone for helping

content: Great. I really was expecting it to be a mechanical issue with a stuck button. The button inputs on the IC are probably pretty high impedance so "contamination" can lead to weird issues.
