Re: Help Needed...1 Tube won't light up on Atma-Sphere M50

If the tubes are both good, then the issue appears to be with the socket. Before you dig any deeper, do you find the connection between tubes and the socket in question to be firm or jiggly? Have you tried holding down a tube in the suspect socket with a little bit of force, or perhaps applying slight lateral pressure - just to see if the tube lights up in standby mode? I've noticed something similar in the past with where the contact between the tube pins and the receptacles in the socket loosens over time. If applying pressure downwards or laterally gets the tube to light up, then your problem is likely a contact issue. I suggest taking a small screwdriver and prying the receptacles in the tube sockets closer to each other such that they really grip the tube pins fairly firmly.
