Re: standy-by light blinking 7 times
From the symptoms you describe, it seems the high voltage flyback
autotransformer has failed along with the horizontal amplifier (they
are slaved to each other). This could have happened during the moving process. The sound comes from the flyback
unit. I guess it must be a high pitched squeal, actually...
Well, the only way to solve this is to get a technician take a look at
the set, I'm afraid. Repairs could cost upto $100 or more, depending
upon the number of components that need to be replaced,
Since the set is new, it may be worth getting
fixed up. If you decide to do so, call around, as shops have different
rates and different expertise. Many shops are hurting for work because
so many of the smaller sets are never repaired anymore; they are just
thrown out and replaced since the cost of a new set is sometimes as low
as the repair expense.
Hope that helps...Should you have any further questions,

In standby mode, the standby light must blink to certain times. If it do so, count the number of blinks at one time. These blinks are fault indications. After counting it, visit this site for more details. [Electro-help].
Type in the site name, either to Google or Yahoo search box and click search. You can see the site in same name as above. It is an electronic equipments repair help site.
This happens when high voltage reaches 33k,it shuts down for safty. Unplug it from the wall outlet,then remove the back from tv,then check the power supply And horizontal circuits.for faults,with an ohm meter,check all solder joints for cold or bad solder connections,resolder most, check fuse,if no reading on the meter with one probe on one end and the other probe on the other useing the ohm scale,replace the fuse. Always replace it with the same amps,its writen on end of fuse......hope this helps...........
Yes, the blinks are error codes. I would not bother trying to figure out what they mean, I can tell you right now. Expensive repair. Average repair costs are 1/4 to 1/2 of the TV's current worth. Most likely a bad transistor. The average expected life span of a TV set is 3-5 years. After that, stuff starts wearing out fast. Time to move on.
could be any number of things ranging from the power supply regulator to the vertical chip audio chip or even the flyback transformer. Definately not an easy fix and would definately be over $200. The flyback alone original from Sony would probably amount to that .
Seven blinks indicates a high voltage shutdown which has exceeded 33,000 volts and immediately sends the unit into a safety shutdown. In this case you would need to check the power supply regulation circuit and horizontal circuit for the failure. It could be as simple as the horizontal output transistor having failed to something more complex or expensive. Need to have it diagnosed for that to find out.
