Dear friend nomoresonys, although I'm new to the forum with few posts, and I might have made a mistake, I checked, and I believe I have the correct answer and recipient. If you have any suggestions for me, I'd be happy to hear them. Kostas...

Yew Diah the link you gave me had 39 very useful photos that clearly show the settings I need to make. When I tried to open the link yesterday, nothing showed up, but today—after hearing from you and Diah—I disabled my firewall and was able to see all those photos!

I also found this link on Samygo.tv from mbjr (https://forum.samygo.tv/viewtopic.php?p=66096#p66096) which contains a text file with a large number of settings, probably from an EEPROM dump. Thanks so much I have lot to do and inform when I am ready....

Hello Davi.p,

The link Diah gave me had 39 very useful photos that clearly show the settings I need to make. When I tried to open the link yesterday, nothing showed up, but today—after hearing from you and Diah—I disabled my firewall and was able to see all those photos!

I also found this link on Samygo.tv from mbjr (https://forum.samygo.tv/viewtopic.php?p=66096#p66096) which contains a text file with a large number of settings, probably from an EEPROM dump.

So, I have a lot of work ahead of me, but the key is getting into the extended service menu, just...

I thing is better to buy one service remote control is very chp!. After that I will enter the settings I found in SamyGo.Tv Diah send me I will inform you when I will be ready...

Hello Diah, I will check Samy.go.tv and I hope to find something to save my old but really
very good TV. Thanks a lot, your help, like everyone else's, is invaluable​...

Hello Lotas, your note and the hint with the image you sent really woke me up, because
I was taking that panel for granted and wasn't paying attention to the model listed there!
Also, the image of the remote control was very helpful. Thank you again. Kostas...

Hello Davi.p, thank you for the very quick response. Your information is extremely helpful!
Despite that, I'm lacking some technical knowledge—I'm not sure how to use the .wav files
you sent me. I will look into it, but even if I manage to access the deeper Service Menu,
I will still be missing the correct values to input. Regarding the Service Remote Control,
I will look into how I can purchase one. Thank you again for all your help. Kostas...

You're right, William1967. You must have looked at the wrong panel in an internal menu;
that was from other tests. It's actually the first option, though of course, I don't know
if that one is correct either, but it's working well. Thank you very much for your help
with the issues I mentioned....
