Hello , my name is Jack Perhaps I can help you with this problem but first i would have a few questions;
Did the tv quit while you were watching it or just would not turn on today ?
While there is no picture , do you still have sound ?
About that blinking light , very often there will be an error code indicated by the number of blinks , could you count the number of blinks in between short pauses ?
I was watching the TV, thought I heard a click as the picture and sound both went off.
There are ten blinks between the short pauses.
O.k then the 10 blinks code can be a bit tricky on this model as it usually can be caused by one of 3 boards that cause a 15 volts line to shutdown .
This line also feeds sub voltages like 9 ,5 and 3.3 volts .
Without getting too much into details I can tell you that these boards are called the SC,SS and possibly P board although the service manual also list The A board which is the main board as a possible suspect.
To make a long story short , this will require some serious troubleshooting.
I can give you the prices of each individual boards and what you may expect as far as repair cost goes but just offhand I would say that you are looking at possibly $300 to have this repaired.
