When I turn on the TV it sounds like starting but the after a second it shuts down again and the Pover lamp is flashing 3 times over and over again
Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672
Testimonial: "OK, thank you very much for Your help. I will take a look at it or else send it for repair."
The four digit number you see is the part number. Here T603 stands for Transistor 603. R762 stands for Resistor 762. You must have sound knoledge in electronics to follow the circuit. This is the main power supply regulator section, where AC mains voltage comes in first, and the gets regulated, and goes to various circuit parts of the TV. This is the most fatal circuit secton for an unexpereinced to work with, because, all parts at the primary side of the main rectifier section will have high negative potential [floating negative], and is very dangerous to touch. B+ ver voltage, means, the regulatoed voltage from the power supply out to various sections circuits, are higher than normal. The power supply regulator section should be checked for fault, ans must set it right at first. A very skilled job indeed.
In my opinion, it will be best cor you to contact any expereinced service technician to get this set repaired, rather than making things more worse.
If you thisnk you are handy, and have confidence that you can do this work, downlaod the service book form internet and follow it.
If you want its repair book, send your email address to me. I'll send a copy of it to you by return mail.

I
have over 10 years experience in electronic tech
support.
I
know this isn't what you want to hear, but the problem you've
described can't be fixed with troubleshooting.
Your TV
will have to be repaired. There is a part that has developed a defect
and needs to be replaced. If you're still in warranty, the TV will be
repaired at no charge to you. The warranty would likely be at least
one year from the date of purchase from the manufacturer. If you
purchased an extended service
plan
they will repair the TV at no charge as well.
If the TV is no
longer in warranty, it will likely cost a minimum of $150 parts and
labor. This is assuming that you only need one circuit
board
or small part. If the problem is more than one of the circuit boards,
the price of repair could go much higher.

My Sony KV36HS500 Trinitron is doing the same thing. Last night the next street over was hit by lightning. The "7" blink pattern was happening, so like the manual stated, unplug it for 4 hours. Which I did. The t.v. is back up and running fine. It's a nice t.v., better than the plasma I paid over a grand for, that's already shot. It's a good t.v. and good that Sony put in the stand by protection to prevent the t.v. from dying an unnecessary young death. Patience, don't rush it, unplug the t.v. and leave it sit. Also, don't use a power strip, that was my mistake, and unplug your t.v. if storms are in the area, I was too lazy to and now I had to deal with this, in 8 years, only twice did this happen. I'd buy another one tomorrow if they still made them.

G'Day!
Unfortunately, what you're describing is a repair
issue. You won't be able to address the problem with troubleshooting.
There is a part inside the TV that needs to be replaced. If you're
under warranty, this will cost you nothing. If you're not under
warranty the cost will likely be a minimum of $200 parts and labor.
However, be warned that the cost could be considerably higher.
I hope I've provided you useful assistance and that this information
allows you to make an informed decision as to how to proceed from
here. Please be sure to vote on my response. I hope I've earned a
good rating from you today.
Please post a comment if you need
additional assistance so that I can help you further.

OK, thank You very much. However I have some difficulties locating the components.
On myTV-set, they all seems to have the letter and a 4 digit number Like Rxxxx og Cxxxx. Are they located on the main power supply board?
Can You maybe help me with the value/type of the components that You are mentioning?
Thanks in advance for your help.
