Question about Televison & Video
Firstly, I would like to ensure you that your power supply is not having any problem. As you were suspecting because of 11V, I must make you sure in electrnics systems its not very sure that always power is exactly what needed. In all electronics equipments we keep a range of DC power supply...
So please, don't worry about power supply. Now come to your problem. Actually, as we are sure that power is OK then in this mainboard problem is also possible but as you have already told that RELAYS are switching properly,it means only internal circuitry of mainboard can have problems.
Since relays works out of modules of Mainboard, so it also refers that mainboard is having some problem. Also, I wanna give you more assistance on such problems.
Generally it is found that these problems are due to regalator IC of mainboard. And solution of such problems needs CRO testing and module-wise checking. And its very affordable too. So, i recommend you to go for a technician & let its regulator IC (named as 7812) to be cross-checked again. And then that person will check your graphic adaptor too.
Surely you will get rid of this problem by this. If you are enough technical person, then do this yourself and no need to depend on any repairman.
Thanking you...rate this solution if it was really helpful to you.

6 or 7 blinks on LG tv is not a fault code. It is only saying that the TV is on protection mode because there is a fault.
LG LCDs have no blink code.
I do not have service manual for your model, but you can check similar models below:

That sounds like a power supply problem. Possibly a voltage rail has gone down. It might only be a blown fuse or a blown component but it could be something more serious if you have already tested the fuses.
Unfortunately, the problem requires an engineer's visit or you could try and find a new power supply on ebay or somewhere else and replace it yourself.
I believe though that you are within your consumer rights to have the TV repaired by the retailer or manufacturer even if the guarantee has run out. Something to do with the TV not providing service for a reasonable amount of time before failing.
Hopefully someone will post information about your consumer rights because I know nothing about them!
All the best
