"only green light is on. tv not work."に関する回答I had this exact problem with my screen black after powering on. Simple fix, these t.v.’s are older…digital signals weren’t fully implemented when they were made. There is a firmware update which will solve this problem I’m almost certain. Go to the Sony website and type in your model number and follow the instructions, you’ll need a USB key to download the firmware to and just plug it into your tv and in 10 minutes you should be good!
