Post by: Minimcauley on November 24, 2016,15:55:32

Please help if u can..... I have the model above and I cannot get any picture in it, it just keeps flashing through the colours and eventually the sound comes on but no picture.
I cannot get into the menu with the remote.

How can I fix this please????

Hi ,remember there was a fault like that on Sanyos and it was the remote control that caused it . All you had to get was to get another remote and use it and it cleared the fault

As Jordan say's it's in burn in mode,for some reason,they just go into it.If menu 4725 doesn't work,try selecting an av mode or dvb mode.I'm sure I had one & got around it that way.

Hi,
Thanks for your quick responses.... I took the TV to the repair shop in the end and he said the motherboard has gone failed.... he can't get the part from his supplier, does anyone know where you can source this part?

Thanks

This is the bulletin for the Sanyo. With the info supplied in prior posts, you should be able to apply it to the JVC.

When I get into the service menu and select "power mode" I cannot change this option it is fixed on standby and is read only.
I've done a factory reset now but when I turn it off and back on it flashes through its colours again.

Shall I just scrap it at this point?
