Toshiba 48L3451db (Vestel 17mb95-s1)

The fault with this Veste TV. The front led flashes red and then green repeatedly the screen comes on but remains blank for around 10 seconds then goes off for around 10 seconds stays off with the same red and green flashing s/by LED. The TV continues in this on and then off sequence. Ordered the correct firmware from Ohms on USB stick but afraid doesnt make a difference. Anybody know whether it could possibly be another problem with main board other than a firmware issue

Just to close this issue. It was caused once again by corrupted software of main board 17MB95-S1. Software from Ohms on usb stick (UPG87) corrected this issue.

Sorry forget the last message. Memory playing tricks! After trying the software from ohms made no difference the problem persisted. Managed to obtain a replacement board from Emos which corrected the issue. Sorry for the confusion of my last post!

Update :
Found a replacement board but tv stopped restarting every 10 secs but ended up with a blank screen no image
Ended up narrowing it down to changing the lvds cable
Tv now in test mode
