Re: Volume goes up all on it's own
The key wire will disable the contact buttons , but it may be the sensor that is doing this and it would need to be replaced or even the crystal on the eprom or the eprom when connections are attached
have you made sure that the plastic buttons are not pushing on the contact button
did you or can you check the sensor with the diode check on the digital volt ohm meter?
a 6ya expert can help you resolve that issue over the phone in a minute or two.

What you're describing sounds to me like "Windex syndrome". People sometimes clean the front of their TV by spraying it with glass cleaner like it's a window (which it basically is) and wiping it off. Unfortunately the cleaner can run down onto the circuit board where it damages the switches and wiring. This might be what's happening in your TV, although the same trouble can be caused by other things as well.
The way the front panel controls are wired, a bad switch can cause all of them to act up. The remote sensor is part of the chain too, and if it goes bad odd things can happen. If the set is in an area of high humidity the same trouble can develop because of moisture. One of the switches might not be operating correctly, or another part in the button chain may have gone bad. The microcomputer in the TV may be bad. If you've had a recent severe thunderstorm with nearby lightning, this may have affected the chip.
Try unplugging the TV from the AC outlet, not just turning it off. Let it sit for 5 minutes to make sure that capacitors have had a chance to discharge. Press a couple of the front panel buttons before plugging the set back in. Then plug the TV back in and see if you still have the same trouble. This process makes sure the microcomputer inside is fully reset and often gets the set going again.
If the trouble continues, someone will need to check the front panel switches and the circuit board. That's the area where the cause will be found.
Please follow the steps below with you sky remote.
RED & SELECT (flashes twice)
Try the volume button if this works the volume then press SELECT to save if this doesnt press the TV button again then VOLUME continue this step until it does work you volume then remember to press the SELECT button to save the code to the remote.
If for any reason this does not work it means that you have an older remote you may need to get a rev 6 or 8 . You can find out what version your remote is by taking the battery cover off the back of the remote and it will state what version remote you currently have.
Hope this sorts you out. If so then please leave a thumbs up
ie menu = Menu
Channel up/down = take you up and down
volume = goes left and right.
follow these steps
channel down button to CHANNEL
press the volume button along
channel down button to AUTO STORE
press the volume button to Start the scan.
right now you have your telly tuned in. What you could do it get an old sky remote off a friend/ neighbour. or buy from argos etc ( a lot cheaper then getting a replacement samsung one)
press the following buttons on the sky remote to program it to work with your samsung tv.
RED + SELECT
try the volume if this works press SELECT to save this code if it doesnt press Tv then try the volume again. repeat this step until the volume works your telly. once it doest dont forget to press the SELECT button to save.
Now you will be able to change your volume use the number keys. if you also press the HELP button on the sky remote this will also change your AV / SOURCE I hope this post helps you out. When it does please leave a thumbs up for me Please
take off the speaker grill, you will see 2 wire plugs, turn the tv on, disconnect both plugs, if it now works with the remote then you need to replace all of the front switches, or leave them unplugged and use the remote, if this doesn't work, you have a bad dm board or signal module which could get very expensive.
RED + SELECT ( hold these down until it flashes twice)
Try the volume if this works then press the SELECT button. If this does not work the volume then press TV again and then try the volume again. Repeat this step until the volume works then remember to press the SELECT button to save the code.
If for any reason this does not work remove the battery cover from the remote. You should see on there ''REV 4,6,8 you may have an older remote in which case you will need to get a different REV remote.
Hope this sorts you out. If so please leave a thumbs up for me Please.
this is the same type of problem happening with other rca models and I know it is the EPROM CHIP but why this is failing is either because of design flaw , dirty enviroment that they were made in , to much voltage or current to the chip or too much of a draw from the chip causing it to fail . Or even a random frequency from the IR sensor or its circut I'm still investigating and testing.
leave the tv unplugged for at least 3 weeks durring this time resolder any solder that don't look good , I did this and it lasted for about 6 months(always plugged in to the wall) before it started doing it again. model # 27v412t
Did you ever get this problem fixed? Ours just started doing the same thing. It worked fine the night before, but today it's doing what yours is doing. The remote stopped working for the TV. The remote still works for the cable box, but volume and anything related to TV function not. The screen flashes when we try to adjust volume or anything else, but resets to previous volume. TV not responding to any commands either on the front panel or remote.
Any ideas? Thanks, Patti
I am having same problem on 32 inch same problem. After playing with board with no results,I tried front buttons and found that if I held the power button in ever so slighItly as not to turn it off, it fixed problem which is the micro on/off switch, I removed the switch and used the remote and everything is back to normal, I am about to insall a used micro switch after I finish typing this but I am sure this will clear up volume problen and menu going crazy problem if not I will just leave micro switch out and use the remote, and I will get back to this board only if that micro switch still causes the problem, so if I don't post in next hour the problem is fixed and I'm more than glad to help.
