found out the time control board went bad which caused the one black line from top to bottom

You need to replace your main pcb.

Hello,
These vertical line are possible causes of LCD cables from the graphics card. There is no easy fix for this issue and normally requires servicing or part replacement. Try to contact your TV support people or consult you local technicians to diagnose it properly as it might be also the panel itself failing.

Yes,it about 90% of the times,it the power supply board.U can look around the power supply board for puff up bulge capacitors,replaced these caps will get ur power back.10% it ur Tuner signal board.If find no defective caps in ur power supply board.Tries websites Shopjimmy.com.Ebay.com to buy ethier refurbish power or tuner boards for the replacement.

Clearly your T.V. is the problem. Always know: whatever unit needs the most adjustment needs, that is the unit that's gonna give first. It's an internal issue, one that should be checked by a service center. There are no connection issues. If it had been then the issue would be continuous.

Most likely you can adjust it in the Service Alignment Mode (SAM).

Press 062596 followed by the STATUS button (upper left). Navigate to "White Tone", press the right key to enter and select "Normal" mode. Set the colors:

Red = 135, Green = 128, Blue = 133.

The "Cool" and "Warm" menus are deltas from the "Normal" settings:

COOL: R -3, G -1, B 5
WARM: R 2, G -3, B -13

Press the "MENU" button to return to the main menu, then the "Power" button to turn the TV off.

It sounds like you have a bad Inverter. we need to run TV in SAM and check for errors. Contact me.

I have codes for access to the Service Alignment Mode (SAM). I can walk you through it. 

I have the same TV that went in for repair and they broke the LCD panel before fixing it. I have the stand for it also. My email is [email protected]

type in Google,,,,,remote for 26pf9966/37. Several service sites will sell you that remote.. Good luck.

It sounds like the controller is bad. Try unpluging the tv and restart after a couple minutes. What happens after you go from an HD product and switch to regular TV? There are codes to input via the remote to run diagnostics but I haven't had any luck as of yet. Could you check for a part on the back of your TV? Im looking for a part # for the metal part that screws into the back of the TV, that holds the tv on the stand. I have the stand but lost the bracket. Any help would be nice. Thank you, John

Remove the cover on the back of the tv. Look for swollen or leaking capacitors. They kinda look like batteries. If they are bulging or leaking then that is your problem. You will have to de-solder the old ones off. Then solder the new capacitors onto the circuit board. Capacitors will cost about 20 dollars and installing them isn't that hard to do. It will fix your tv 99% of the time. So it is worth a try!
