Hello Papalion,
This is most likely due to 2 problems -Temperature or a bust capacitor,
1.
There is a simple trick...just warm the back of the TV with a hair
dryer for 5-7 mins after you have unplugged the TV. Look for the little
areas of holes in the back panel of TV. Use these as your guide at
where to use hairdryer., but don't hold the dryer too close(say
5-6inches away). (Make sure the dryer is on High heat). If the TV
doesn't turn on after you have heated it up (like it tries to
come on but then turns off) you need to unplug the TV again, this
resets it. And repeat those steps till it works. Reseting the TV after
it fails to turn on is the key. Also, just leave the TV on. Don't turn
in off. Since it is LCD, it doesn't take much power...only a few bucks
extra a month for your utility bill.
2.
You can also try this..if you unplug the TV, and hold in the power
button while plugging it back in, this will reset the TV, and sometimes
it comes on.
3. If you want to go in for a long term solution,
you can easily replace the whole power board (should be about $20 or
so), or just change the faulty capacitors. You can make out which are
faulty, because their caps will be swollen on top.
Check
the specifications of the faulty capacitors, and get the replacements
from your local electronics shop. If you are comfortable with this, you
can use a pair of needle nose pliers to G-E-N-T-L-Y pull out the
defunct capacitors. Once that is done, solder in the new capacitors
carefully. If are unsure how to do this, try to get a friend who knows
how to do this kinda stuff do it for you.
Hope that helps...Should you have any further questions,
please feel free to post them here.

Hello Papalion,
Sorry, I seem to have typed the instructions for another problem I was solving simultaneously with yours, in here. (Hope I didn't type in your solution in the other post..hmmm..) Please pardon my error. But do go ahead and try the hairdryer and reset suggestions above :)
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,
please feel free to post them here.
Cheers,
IrishDruid

Hi there. Is there any chance that the set may have had a rough ride if it has been moved?
Sometimes, if there has been a rapid downwards deceleration, a PCB may crack about some of the larger components. You can inspect the PCB's for fractures, and then repair them. It may also be poor soldering that has failed from the move. I would be checking for these things first.
Powering down the set fully may have also allowed the power supply to cool, weak capacitors often go out of spec when they cool, this preventing may have prevented a section of the power supply from firing up properly again. If you care unsure, it may be time for a sony tech to take a look at it for you. REMEMBER there are very dangerous voltages inside a TV that can KILL. Be sure to work SAFE when dealing with electricity. DISCONNECT THE POWER BEFORE YOU DO ANYTHING.
regards

Hi IrishDruid,
This is not a LCD type tv. It is a WEGA CRT Sony. I don't think the dryer trick will work, but I will give it a try. I will try the reset.
Thanks
