Question
Hi there, thank you for your time.
I have a Toshiba LCD TV Model No.46WL800A. Over the past couple of weeks my television would turn itself off, whilst I was watching a program. So I would turn off the television and pull all plugs from the wall, after a few minutes I would reconnect all, and it was working again. Until 3 nights ago, the TV turned itself off once again, I repeated the same procedure as before, but unfortunately the TV would come on for approximately 30-40 seconds and turn itself off. I left it for a couple of days not connected to anything, reconnected the TV, only to have it turn on again for approximately 30-40 seconds, also the blue power button would flash. I have tried resetting the TV by holding the power button to no avail. Unfortunately the set is only 18 months old, so, do I need to replace the set or is the fix not to expensive. Thank you again for your time.

Answer
Sorry, I don't know the trouble codes on this model. Many models of other manufacturers use the blue light flashing to indicate time to replace the back light. I don't know if that is the case with your set or not.

The set may need replacement of one of the boards.

Why don't you call the local Toshiba representative or the store where you bought it and see if they can get you an answer.  It is likely a common malfunction that they have a history of.

Sorry, I couldn't find the service manual for downloading - which is where the trouble codes and subsequent repair would be outlined.

Hope this helps.
