There probably was nothing wrong with it to begin with the analog OTA broadcasts it was meant to receive stopped around 2009 (do the words DTV transition ring a bell?)... The only way that is getting a signal is it you hook it to a DTV converter box, cable/sat box, VCR/DVD player, or an older game console...

Most tubes look burned out whether new or used...People tend to mistake the black factory getter blotch inside the glass for signs of burnout, but those blotches are normal and meant to be there...The only time they indicate trouble is when they turn white...It means the seal of the glass was broken letting air get in.

Most tube TVs have a tube layout chart stuck inside the back, on the inner sides, inside the top or pasted outside on the bottom. each tube should have an ID number that consists of 1-2 digits, 2 letters and a digit (Such as 6GH8, 17DW4, etc). Match the tube number to the numbers in the circles on the chart and the circles on the chart will match the positions of the sockets.
