"the standby light sometimes flashes 5 times every 3 seconds" (sic) With regard to those flashes, if there is no mention of it in any of the manuals, from the links i have provided, then i would just keep an eye on it. But you have no real problem.

the power supply section should be resoldered....must be loose contact..in power section...

The LED used in most tv are dual color led,some have two lead, some have three. try to find the same size and replace it.

hi

you have defective power oscillation in power section
this needs to diagnose for a qualified technician

Thanks!

NO PICTURE IN SCREEN

i think your tv had a lose contact or crack on board

The Sony error codes go up to 7, so when the standby light flashes 11 times it usually means that one of the clock or data lines deep inside the set is shorted to ground. This is not fixable from the front or through the remote, so the set should be serviced by a qualified tech familiar with Sony sets.
