Video boards Had to replace the power board. Television now powers on, but there is ghosting of images and distorted color. I have tried to adjust the picture settings to no avail. There was never an issue with any imgae burn or color issues prior to replacing the power board. Before I replace the video board, is there anything else that may be causing this issue?

What I'm learning is there are several models of Panasonic TV's that have a video card that doesn't play well with HDMI applications and the end result is, you need to call this number and not only make arrangements to replace the bad board,but also this!
Your model doesn't show below,but I'd certinly inquire about the necessity of a "Firmware" update!,,,Panasonic knows FULL WELL they have a HUGE problem here!
Hope this helps!

Hi
A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this helps

Hi.

If you got quoted over $500, then you have probably wrong part. Cost of this TV PSu ranges between about $150 and $200.Part number for the PSU is ETX2MM681MFS. The number may be different from one on board in case the original one was discontinued. Check what number is printed on your PSU board

Price from Panasonic is about $250, I am not sure Pana sells this parts from users.
Here the part from third party at $130: http://www.tristatemodule.com/p-4026-etx2mm681mfs-panasonic-tv-module-power-supply.aspx

Here a company that offers repair of PSU (board only) at $140: Panasonic TH-42PZ700U Power ETX2MM681MF REPAIR SERVICE


Replacing the board is not really difficult. Replacement is done removing rear panel, undoing connectors, removing a set of screws, removing board, putting new board and reversing the rest of assembly process. The board is not difficult to access, in some model you may have to undo also the secondary power board.

However remember that this set is not a personal computer. Such parts are not supposed to be replaced by the user, and there are many tricky parts unless you have technical training and experience.

Parts are very sensitive. You may easily fry an expensive main controller board if you put the finger in the wrong place.The job must be done wearing wrist band or anti electrostatic gloves.
All the screws must be well in place. Screws adherence to chassis and board warranty proper grounding of board, without that the TV goes in protect mode (forced standby).

The most difficult part is testing the power board to know that this is the problem. This PSU has a series of connectors that supply power in different voltages. Even if you have blink code pointing to PSU (eg. ten blinks) the board mustbe tested the same, or you risk to replace the wrong part. A defective main controller may wrongly point at the PSU. Here an article summarily describing the how to full PSU test.

Concluding, replacing the board is not a too difficult task. Check the board part number and replace with the same or with ETX2MM681MFS. Replacing the board is not too difficult, but if you have no tech training, you take the risk.

If you repute my solution helpful, then please take some times to accept the solution. Providing good repair tips requires time and skills, and your feedback is important for us.

All the best.
