The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Sony kp-65wv600 projection tv error code. My tv blinks 7 times.


Hi,
The Standby LED blinks when the TV is turned on, then shuts off when the picture is displayed. If the LED blinks continuously, this may indicate that the TV requires service. Before getting the TV serviced, try power resetting the TV and factory resetting. Try the below steps also: Connect the TV to a different wall outlet and check if it helps. This is to check if the issue is with the Power. Disconnect the TV from the Power Strip or the Surge Protector and connect it directly to the Wall outlet and check if it helps. To Power Reset the TV, disconnect the Power cord for a short period of time (approximately 1 minute). Then, reconnect the Power cord and power ON the TV. To factory reset the TV, turn it ON. Then while holding down the RESET button on the Remote Control, press the Power button on the TV front panel. The TV will turn OFF and then turn ON again. Then release the RESET button to complete the reset procedure. If the issue persists, service may be required.
Good Luck!!
