No picture on Panasonic Plasma HDTV
Posted on 2012-09-04
I am working with a Panasonic TH-42PX80u plasma HDTV. The tv has a soundbar connected via hdmi. A blu ray player is attached to the soundbar receiver. Everything has been working correctly for quite some time. Recently, I added a cable tv digital converter. When I went to connect the hdmi cable to the digital converter, there were some bad sparks and it burned the hdmi cable. After this incident, the tv no longer has a display. It no longer seems to respond to remote controls or the built-in controls. The only button that works is the power button. When pressed, the tv powers up and it illuminates; no picture, or input indicator, just a solid red power light. The tv also turns on through the auto-synch feature when the blu ray player turns on. I have tried all hdmi inputs, but have not tried other inputs. Any ideas on what's wrong? I'm thinking either the system board or input board could have become defective.
