Hey! I have an old samsung TV, not quite sure of the model because I was gifted it by my granddad. I was playing a game on PS4 and left it on standby whilst I did some other stuff and when I came back, I saw the volume going haywire in the screen. It was a hot day and my room is super stuffy but I have never had any issues with it on other hot days. I was wondering whether overheating could cause this? At first I thought it was the remote so I took a battery out and checked with my phone to see any flashing but there was nothing so it’s not the remote, I read also that it could be an issue with the volume board inside and that I could disconnect it but I’m a minor and nobody in my family is really a techie person and plus it’s hooked up to my wall. I turned the TV off for about 2 hours and turned it back on again but it didn’t help so I’ve unplugged it and let it cool down and will try again tomorrow incase it was too hot. Can anybody provide an insight? Thank you!!
Hi @vivienna, Since you have proved that the TV remote control was not the cause of the problem, there may be a problem with the TV’s volume control buttons. If the volume is still behaving erratically, try pressing the TV volume control buttons (both Up and Down) to see if this has any effect on the problem or even if it makes it stop. If still no good, the TV would have to be removed from its’ wall mounting so that the button control board could be disconnected from the mainboard to check if the problem stopped or not. If it is decided to try this then be safety aware as there is exposed lethal voltage in the back of a TV. Disconnect the power from the TV before removing the back cover and never work in the back of the TV when the power is connected. Once the button control board has been located , disconnect the cable from the board (or the mainboard whichever is easier to get at), connect the power to the TV and use the remote control to operate it. Since you haven’t said what the TV model number is, it may be that the TV’s IR (infra red) receiver is on the same board as the control buttons. If this is the case you cannot use this test to determine if the buttons are the problem. Look for the IR “window” usually located on the front bezel of the TV under the screen and where it is in relation to the control buttons. If they are very close to each other then they may be on the same board The model number will be found on the back cover of the TV, so it will have to be removed from the wall to find out I doubt that overheating is the problem. It can affect electronic devices but in this case it seems too selective about what it is affecting. There should be other symptoms as well unless it is just the audio processor on the mainboard, but further testing would be required to prove this or to determine what the problem is.
