Only ref we have isTAV-L1 and also on back of set it gives a serial no(###) ###-####
Ahh yes its the home theatre combi I just thought it was TV
OK whats happened is the mainboard in the set is not sending back a command to unlock the powerboard so its highly likely that the mainboard will need replacing (subject to checks with a meter) if you can use a meter have good hands on ability I can help you with this ?
If not you will need a engineer who may charge £180_£200 for a set of this spec.
Let me know if you can do the work or need more info
