Hi Larre! Thank you for choosing ExpertHelp.com. When did you replace the circuit board of the tv?

I see. Are you using a surge protector? Can you try these. Unplug the power cord to the set, wait 10 second then hold CH UP and VOL UP together and plug in the tv and continue to hold the buttons until it powers. Advise me if you will still see faded color on the tv side.

Okay, then just let the tv power on for 30 minutes and advise me if anything changes. I will be standing by.

Can you try these. Unplug the power cord to the set, wait 10 second then hold CH UP and VOL UP together and plug in the tv and continue to hold the buttons until it powers on. 

Can you try this another steps.

1. Unplug the television.

2. Press and hold the "Channel Down" and "Input" buttons on the panel.

3. Plug the television back in while holding down these buttons. You may need the assistance of another person to accomplish this step.

4. Keep holding the buttons until the television powers back on.

Advise me if there is any changes.

Okay now use the remote to navigate the "Service Mode" menu and select "Factory Reset" from the menu. Click "Enter" and the television will begin initializing and shut down. It will then power back on, set to factory defaults. Advise me what will happen.

Just wait for 20 seconds. If still not powering on power on the tv.

Power it off then unplug the tv and then while the tv is unplug press and hold the power button for 30 seconds and the plug it back in. Then check the picture if its still distorted.

It depends on your tv menu options. As long as you see the factory reset mode it is the same.

There is a possibility that there is some loose points on the tv panels. Can you double check if all the connections on the service circuit board you replace are all properly connnected. There is a big possibility that there might be a loose solder points when you replace or when you move the tv.

Probably Larre. So the best way is to check the components again. :)

Possible. Because when you replace the tv circuit board everything is working properly. Are you using a surge protector?

I see. Most probably the Circuit board you replace might have issues thats why this is happening again. But I suggest to check the Main board and also the Tcon also. But 90 percent the issue might be the circuit board again.

You can post it on this page.

I will.

Do you have a cable box? If you have are you still having the same issue?

Do not replace the circuit boad. Try to check the backlight of the LCD first. There is a possibility the backlight might not functioning properly. As check the picture it is a LCD issue not the Circuit board.

Try to check the LED panel first Larre. Check if there is any broken Possible LED backlight failure.

On my own opinion I will buy a new one. The cost of the repair and the parts is just like buying a new one. What I recommend you is try ti switch brand and try Sony or Samsung. And you will get a year warranty :)

Hope I answer all your question. Is there anything else I can assist you with.

You have 30 days and you can always get back to this page if you have follow up question. Is there anything else I can assist you with? :)
