Hello, F76 is a power supply failure with the Panasonic Blu Ray home theater per the service manual and this requires replacement of the power PCB in the unit, which costs close to what the system cost when new. Regarding the fine lines on the screen of the TV- these could be caused by lots of things- it's impossible to troubleshoot without knowing- what is connected to the set for sources, whether or not the lines appear over the MENU, etc. They are likely to be video noise appearing in the video processing of the TV- which would also require service to the set. If you need further assistance let me know. Please do not forget to click a POSITIVE RATING before you go- as it's how I am credited for my work. You can follow up at any time, at no additional cost.
