TV Technician: Jack, Technician replied 2 years ago

TV Technician: Jack, Technician replied 2 years ago

With the volume + and channel down procedure all you do is defeat the protect circuit , its not a reset and does not fix anything

How is the screen looking while its on ?

Are there darker areas ?

That code points to a lamp / panel error as I`m sure you are aware

TV Technician: Jack, Technician replied 2 years ago

If you want to enter the service menu you press VOL - and INPUT (not chan up) while you press the power button or plug in the power cord.

I have to step out for a bit , take a look at the manual at the link below in the mean time ;

click the link below and if that link opens a login window popup then just close it with the upper corner X or the "no thanks . continue to view"
The manual is behind that , use the download button once its opened .

Hope that the manual will help , especially the troubleshooting table on page 69 and on .

In your opening post you did not have questions just a statement of what you did so far so I figure you already know that this points to a panel problem and on hand troubleshooting is what would be required now.

If you don`t have any questions for now then please do take the time to rate my answer by clicking on the star icons at the top, then click on Submit , this is how I make a living and that rating gets me paid for my time.
Also note that it will not close this post , you can come back here at any time if you have questions.
Thanks for understanding .

By the way , got some new info on this problem ;

If the only way you can turn the tv on is by the force procedure and the screen displays evenly no dark area then replace your main board
