The Tv is on. Like I said. All voltages ok but no image ...
TV Technician: Master Fix It, Technician replied 6 months ago

Thanks,

on this one get really close to the set and look at it in different positions, let me know if you can see a faint ghosting image at all, try this in different lighting conditions.

Thanks

I already did that last night and as far as I can see , no flash or dimm light on screen.
The led in the ctr board is still off meaning the ctr board is not activating the Y-board...
TV Technician: Master Fix It, Technician replied 6 months ago

Hi, yes that is correct.

Have you checked all the power supply output voltages?

Ask Your Own TV Question
Customer reply replied 6 months ago
VA VS VSC VZB VDD all correct (checked with the panel sticker)
.. the front led of the TV stays on green (no blinking)
Customer reply replied 6 months ago
Also tried the self test on the ctrl board and no pattern was displayed..
TV Technician: Master Fix It, Technician replied 6 months ago

Hi, unfortunately given all that information.

You have a bad Plasma panel.

It is extremely expensive to order and replace. In this case, I really would replace the set.

You should at least have the ghosting, that would indicate a lighting circuit issue. But you have nothing with all else showing normal.

I wish I had better news for you, I really do. I have been a TV Technician for over 35 years hands on, so I knwo this well:-(

Please rate my service kindly, it is the only way I am credited for my time and expertise with you.
Once you rate, I will be notified and will add your question to my priority list so you can reach me anytime until this problem is solved.
Then you can reach me by simply replying to this message anytime.
Thank you and have a Wonderful day!

No additional cost to rate kind;-)
Sincerely
Tech Michael

But why the led in the ctrl board is not lit ?
Customer reply replied 6 months ago
jus a sec I'll be back in 10 min)
TV Technician: Master Fix It, Technician replied 6 months ago

I will be here for another ten minutes this evening, then off until tomorrow morning at 7am EST;-)

If you haven't done all the voltage checks, you will need to do them.

I will get a copy of the service manual and the schematics so I can work with you. But usually this condition indicates a bad plasma panel.

Please rate kind (no additional cost to rate)so I can remain with you it may take a day to get all the paperwork we need to troubleshoot this down to the panel;-)

Thanks for your patience.
