before we take the tv apart we will do a self diagnostic test on the tv. See for more info in the service manual that i add to this guide.
for a self test on the tv , push following buttons on the remote: display button ( see picture for more info on this button ) channel 5 volume down and than power button.
due to data loss on my pc i lost all the pictures to make this guide.. if you have question , feel free to contact me.
