then at least look at the suggestion p0tsm0ke just made earlier about the tcon board replacement
the T-con board drives the panel, and from your description of symptoms it is not certain it is the panel itself . the tcon board (or power suppy) faults are more common with power on self-test /shut down failures . Panel failures usually
show verticle or horizontal lines or partial illumination (sometime half screen or less), or sometimes a double image. the led back light driver board /main board fail can also cause a shutdown.
what would argue against this is that with sony the 5 red flashes
indicate "an error for a bad lcd panel connection, or an internal lcd short". both would be an expensive fix for a technician to spend time to track down and repair. however the t-con board (or bad connection thereof) can also cause the same error.
doing a quick google for the 5 flashing red lights error on sony lcd tv's gives some good information on some of errors you might be able to fix yourself (like the Tcon board), and i wouldnt rely on the average technician being able to provide an accurate and final verdict on the cause just on a quick inspection. if the screen shot you included is from your tv, how come it still turns on with an image on screen if the screen is faulty ? (might not be your tv then) and the tcon errors show would increase that as a worthwhile try to replace if the board is inexpensive and easy to access
i have no idea on the price for these (might only be 50$ ?), but it wouldnt be to hard to replace this yourself. worth a try if you are giving up on your tv anyway (unless sony takes it back for an exchange, in which case dont open it up or it might possibly invalidate your return/exchange)
