Hi.

4 blink is power board SoS. The problem is either a faulty digital board or a faulty power board.

A way to troubleshoot the error is reading if the pin 12 of connector from power board to digital board is high immediately before shutting down. If it is high , then it is the power board, otherwise the d board.

A different thing is if you get 8 blinks, in that case the problem is the sustain board (8 blinks = sustain energy recovery).

Test and repairing must be done by a technician.

If you need parts , or if you want a quote on repair, try calling the number listed on the user manual.

As first troubleshooting try leaving the power cord disconnected for about thirty minutes. This will drain power held in PSU board capacitor, and can fix minor problems concerning power board.

Regards.

Hi there,

Did you have any success with the stand? if so .. if you haven't already sold it are you considering selling it?

All TV's have an Analog or Digital, or sometimes BOTH tuner(s) in them, and are able to receive free to Air TV, via a suitable terrestrial Antenna.

its the video pcb i have the same problem

Hi.

The 3D Y/C filter in the menu is not an option to get a 3d picture, but simply one of the many filters that you can use to improve picture quality.

The 3d y/c filter minimizes noise and cross-color in the picture. If the picture is good, leave the filter off.

10 binks with no turn on is a power supply problem, u will need a service rep to run a full diagnostic of the tv to figure out what parts need to be replaced.

Hi,
This is a fairly common problem. usually it is about a 40$ board that needs to be replaced. Now that isn't always a 100%. It could be a more expensive part that has caused the cheaper part to break. In that case the next part is about 400$. Then I would probably recommend purchasing a new tv rather then repairing the television.

If you are considering repairing this tv yourself. I would highly recommend getting the service manual.
If you have any other questions please let me know.
Thank you,

What is the red light blinking? Count the blinks before it pauses and post back here. It'll give me and everyone else a starting point.

Check ur Caption functions?Tries turn off everythings involve captioning off or reset to factory setting.Still the same result must change the Main Tuner signal video board.

Hi:
You must replace the Y-substain Board the PDP chip on this board is starting to fail, sooner or later you will hear a some what loud pop and the unit will not power up because the chip on the Board has failed or shorted, this could also cause power supply problems down the road.

is your input using component(red, blue, green)?

You could have one of three problems. One is really expensive to fix and you might want to trash the set. Thats if the panel is bad. Secondly, it could be a buffer board that went bad. Not as expensive as the panel. Finally, it could be the connection between the two. I would first take the back off and locate this board. Undo the ribbon cable and clean it off a bit and put it back. If its still there, you have a deeper problem.

The buffer boards are located across the bottow when you take the back off. About 3 inches wide. Sometimes they are on the top as well.

You starting point would be to look at the SC, SU and SD boards. Maybe (Very unlikely but possible) the panel. You would need to know how to trouble shoot those three boards to know what board you need.

What is your problem? you really didnt say.

Connections on c boards, c board bad or bad panel. Disconnect power supply from sus boards on sides before attemting to disaconnect connectors from c board to flex cables. arc from stored energy on power board will burn cables. reseat the connector closest to the bar . reconnect power supply. Next replace that c board by strip. next replace plasma panel.

Stick camera memory card into memory card slot on tv. If it does not automatically switch to that input use the remote to change to that input.

i have proble several time in a day

The tv needs the X/Y sustain boards serviced or replaced, it could also be the buffer or DC supply also. Take it back if its under warranty, if not have your local shop service the tv for you...
