Try hard resetting;

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.

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!!

When turn on tv with remote and without remote it


I have the same tv. Something to remember is that the picture is lamp powered. It takes about 30 seconds to power on and takes about a minute to fully power off. I had issues when trying to turn on the TV, accidentally double tapping the button, which would turn it back off. I'd do the same when trying to turn off the tv.

If you are sure this isn't the issue and the lamp light is still on once the tv turns off, most likely your bulb is burnig out. You can find replacement bulbs on the internet. They are fairly easy to install yourself, so you shouldn't have to have the tv serviced.

If the bulb seems fine, your tv could possibly be overheating. In that case, make sure the vents are cleared as the tv gets pretty hot.
