@mrs_copus your panasonic only goes up to 14 blinks on POST so there is no 20 :-) Since “the Tele itself is turning on” and “no sound or picture is coming on” is a pretty good indication that your TV has issues with the A-board. That is teh board that has all the video connections etc. Remove the cover from your TV and take a look at all the board and interconnect cables. Check for any obviously damaged or missing components. Post some pictures with your QUESTION of those boards so that we can see what you see. 在已经存在的问题里加入图片 If you want to check the A-board and have a multimeter you can check the voltages as follows
Description Test point Voltage
SUB3.3V TP8615 3.21V - 3.45V
SUB 1.5 V TP8101 1.47V - 1.56V
SUB1.2V TP8100 1.26V – 1.33V
SUB5V TP0910 4.8V – 5.2V
PD1.2V TP6700 1.08 – 1.32 V

Mine is doing similar. I have to keep turning it on and off with the power button on the back. It does eventually come on but takes about 20 goes. Is it worth repairing or should I just buy another 50ax800 series
