Sony Bravia KDL-46HX720 5-blink code?
I'm troubleshooting this TV for a friend. It shows nothing on the screen but the red, standby light flashes 5 times repeatedly. I believe this indicates an LCD panel problem, but I could not confirm that the info I was using is correct for the model number. Does anyone have access to the service manual? I accidentally killed the power supply board with the test leads, but it seemed to work before then (3.3 volts at the stby terminal and 12v at the 12v terminals). I believe the LCD panel replacement is prohibitively expensive, correct? Thanks for any insight.
Model number correction: KDL-46HX729. It appears to have a LTY460HQ04 LCD panel.

More than likely it is the power circuit board on the tv. This is a common issue with bargain price tv and the lower end models. You can call or email the manufacturer and see what they say. Sony customer service are not very helpful from my personal experience, that is if you can understand them. It may not be cost effective in repairing than just buying a new tv, if you do not have a factory warranty. Hope this will help you out.
