Sounds like either the LCD is bad, cracked, or there is a loose connection from the main board to the LCD screen itself. Best bet will be to hook it up to an external monitor to see if you get video on that, and the repair for an LCD is just a matter of ten to twenty screws, and one or two plugs. Not too bad.

The factory diagnostic for an 8 blink error code is: Driver SOS 3 SS-Board / SS2-Board; SS FPC Detect; SS Energy Recovery Circuit. Basically it means that the current absorbed by the X-Sus board is too high. It looks like this

You will need to open the tv and check the connections to this board and all the components on it. Also check the filtering capacitors from the power output line that powers this board.
If you can't find anything wrong then the entire board will have to be replaced.

Panasonic Viera TH-42PV60H displays vertical lines on left side of screen.\r\nThese lines flickers and changes colors. Initially was about 2cm wide and now it is about 4cm.


Either LCD transistor got moist or the video chipset got condensation. Keep TV on standby to dry it out. Unless there is also mechanical damage to the lcd screen on the edge..

Plasma tv th-42pd50u not come on and keep blinking red light two times and then stop again blinking red light two times and then stop not come on


The light blinking twice means there is a fault within the system and it is a code to tell Panasonic where roughly the fault lies.
Go to Panasonic's web site and look for your set then input the fault code and hopefully they will tell you where the fault lies.

TH-42PX60U red light blinks 10 times wont come on


On a Panasonic TV the 10-blink error code can sometimes be caused by low voltage running through an HDMI cable, particularly from a Media PC or some video game consoles. Try disconnecting any HDMI cables and unplugging the Television for 30 seconds, then power it on without the cables attached.

If this works, connect the cables to the front panel (usually HDMI-3) which uses a different controller board.

This problem is usually the ribbon cable connection at the top of the stripe. Reseat the cable first. The other possibility is the panel itself, but that is rare.
Keep us posted.
