7 blinks is an error code for "Audio Error" upon self check of the unit. It will not power up and will repeat the symptoms unless the faulty parts are isolated. This was caused by short-circuit of Audio power line in the K board. Faulty parts are the following :
1. PS3001 - Open fuse in K board.
2. IC3005 - shorted 12vdc line regulator IC.
You must replaced this two parts so that the unit will back to normal operation again.
If you don't have necessary tools and can't troubleshoot the unit yourself, I would advice you to look for a qualified TV technician to isolate and replaced this parts.
Also, you may replaced the entire K board for your convenient, click this LINK to place your order online. Board replacement has no soldering required, just pull-out the connectors from the defective board and put in the new board.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Five blinks - AKB
circuit (automatic kine bias), the timer/standby indicator blinks
for about 30 seconds then goes to the self-diagnosis function.
Something is wrong with the video. Check video out, Q705, 732, 761
and other components on the C board, also check Q218, 219, 220 on
the A board. In addition, unit could be in IK blanking, try turning
up screen A2 slightly.
