What causes the picture on my Toshiba 47ZV650U to go blank but the sound is still ok and the power indicator light on front is blinking

SOURCE: power indicator light blinking

Check soldered in micro fuses...F850, F851 etc.....
1) solder jumper wires on signal board = 008,010,017,048,600
2) Check / replace STK392-110 convergence IC's with Toshiba
part # 23135090 or upgade to Hitachi part # CZ01341
Let me know....................T.

Had the same problem myself. Took some doing but I managed to find a service bulletin that I downloaded. The problem is with the siene module and all you need to do is unplug connector JP63A from the main board and your TV will work again.
Take the back off the TV (there are a lot of screws) and look on the left hand side of the main circuit board that is mounted in the center of the TV. You will see a small white connector that is labelled JP63A, simply unplug it. Plug the TV back in and let it reboot. That's it, should be able to watch immediately.

If it shuts off and then the power light starts blinking red or it never comes on but the power light just blinks red continuously that is usually indicative of the convergence ICs (STK 392-110). You never want to replace the ICs without also replacing the resistors that are associated with them. There are usually 6 resistors, one for each of the colors and there corresponding direction, IE Red horizontal, red vertical, blue horizontal, ect. In the case of this model tv all of the resistors are 2.2 Ohm and 2watts. You will find them right where the STK 392-110 ICs are. Right in front of them. They are blue and have this color code on them. Red, red, gold, gold. These are represented by stripes on the resistors. You can get the parts from www.bdent.com They carry the ICs and the resistors. If you do not feel comfortable completing this repair I could do it for you if you send me the board. My email address is: [email protected] The cost is 375.00 and that includes parts.
Good Luck.

The TV is going into protection shutdown mode. Something insdide has failed and should be looked at by a qualified technician.
