Circuit board attached to ps is broken into two, Where do I get another or can I repair it successfully?

It should be soldered to the circuit board. Look for a spot of solder that has some wires in the solder, but not attaching anything to the board.

in 30% of the cases the problem is on the main board or in 10% t-con is on short circuit

It's real easy. Just turn it in for repair, and watch tv someplace else. Save up money, by the time you have it the tv might be fixed. If not, the repair shop will hold your tv and your money. You can make payments and stuff.

if the outer case says no user serviceable parts inside, I would speculate no...sometimes they solder these connections into the circuit board so you are better to get another box than fix the one you have..

The jack is LIKELY surface mounted on the circuit board and broken loose. Only thing is to take in for repair. Surface mount repairs are not for the unskilled DIY. It usually takes special tools to safely replace or re-attach the components.

Only attempt this repair if you need the information on the USB drive as they are fairly delicate devices inside.You should be able to repair it if you have the right fine soldering iron and good soldering skills as the printed circuit board tracks will be very fine: you will probably need to very carefully re-attach the USB plug to the printed circuit board with strong epoxy glue and then ensure that you re-join (with the help of extremely thin electrical wire if require) all the tracks to the 4 USB pins. The Electronic is very static electricity sensitive, so make sure that you do not ZAP it by first earthing yourself! Hope it helps and Good luck!

Broken LCD panel does not affect circuit board behind that panel.
Make sure that other TV should be same model (KDL-40W4100) to swap boards / LCD panel because each model has its special designed boards and cannot be used in different model (if chassis is same, few boards can be used)

Most shutter buttons are plastic discs attached to a spring-mounted plunger on a circuit board. You might be able to purchase a used as-is camera of the same type. Try taking the body halves apart carefully on the as-is camera, remove the shutter circuit and then carefully try to replace the shutter button circuit board on your broken camera. Or if that's too difficult, contact the manufacturer or any reputable repair shop and get a repair estimate on the camera. If the estimate falls above the value of a new camera - you decide. Hope this helps. 

That is a common problem with Mp3 players - unfortunately, no one that I know of yet has been successful in repairing this issue, b/c the manufacturers do not sell the component parts. I'm afraid this Mp3 player will have to be replaced, even though only the headphone jack and associated circuit are bad.

six flashes corresponds to "Horizontal deflection stop". In turn the "supposed malfunction" is then either Q5013 (H OUT) is broken and/or IC507 (H Jungle) is broken.
however i would check
Video out, IC7101, 7201, 7301 and others in C board circuit.
Q510, 516, 524 (A board).

There are actually three C boards, the CR, CG and CB boards. They are attached to the rear of the red, green and blue CRTs, respectively. I wouldnt attempt to repair the set myself. I would solicite the services of an authorized Sony servicenter.
