Question about Panasonic Viera Tc - P65S2 65 inch 1080P Plasma Tv
My tv got the 7 blinks of death (as people call them) about a year ago. We didn't stress about fixing it since we had another tv. Now that we are moving things around, we wanted to fix it. Well I did some research and figured out it was the SU and SD boards. I replaced the boards and it turned on right away. But now it has this huge 4" vertical black bar!! It is slightly right of the middle of the screen. It is completely solid and cannot be seen through it. I unhooked the corresponding ribbon to that area (power off of course)and reseated it but the bar continued there unfazed. Do I need to order me the board that's running this area or is it possible it's something else???? PLEASE HELP!! Any help will be greatly appreciated!! I'll try to post a pic as soon as I find out how to. This is my first time using fixya.com... Thanks again in advance.
By your detailed description, it sounds that there should be a loose connection with the 'COF'; connected to the screen. All of these COFs, can be located at the bottom side of the screen [looking from back]; in a horizontal row. If you wish to get more details to this fault, check the site kinked here. It has screen-shots of defective plasma TV screen, and possible faults.
I should appreciate you for this detailed description, that a few users will provide.

SOURCE: TV Won't Turn On
I purchased the TV using AMX card 18 month ago. They have an extended 1 year warranty on top of manufactory's. I just have this set repaired: replaced SD board, total charge is $550. I already file a claim and hope to get reimbursed soon.

This is not video board problem. It is actually a power supply problem.
The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.
The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board.
I do not think it needs replacement, rather some defective capacitors are causing this issue.
Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.
The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)
You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.
What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).
You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors).
After replacing these capacitor(capacitors) most likely the normal operation will be restored.
Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.
If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.
I hope this helps.
