They for the most part only sell boards for these--the error codes can be misleading in many ways---suggest you Google the model number and see what boards are in it and what they cost to decide if set is worth a shop repair or not.

SOURCE: sony kdl-40xbr lcd tv.. turns on for a second then

I am pretty sure this is a Back Light failure or a bad Ballast. If it is the only fix is to replace the LCD Panel. I would contact Sony at 1800-222-Sony and see if the could help you with repairs and also to get a Factory Service Facility near you to confirm the problem.
Hope this helps,

SOURCE: Sony KDL-46XBR4 - no picture or sound (black screen), the standby led blinks once then recycles each time the sony lights then goes out after 30 -50 mins the set comes on.

There is a high possibility that the components over a period of heating and cooling, tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs or poor performance. The best way to check for loose connections is to tap lightly when the set is powered on, if there is change while tapping then it seems that there are DRY solder joints. Remove main plug, the covers - with caution of high voltage, check for dry joints, and use a good soldering iron to solder all suspected points. Sometimes the fault occurs when the set warms up; if so you can simulate the heat using a hair dryer on the suspected areas, try with the power supply, distribution, Processor controller, driver controllers on the A/V related sections. Also the use a FREEZE-IT spray can simulate the components to cool and show up the fault. It can also be related to WEAK ELECTROLYTIC capacitors as the value can reduce in time. Based on the above method you must be able to locate the area of fault and solder the sections.

Sony Bravia KDL 46", no picture, standby light blinks 4 times


Since the TV is still receiving power, the problem is going to be with the TV's mainboard.  After you unplugged the TV and plugged it back in, you said the power light went out again, so I assume the standby light wasn't flashing again?  The flashing standby light is indicating an error code so my suggestion is to contact Sony for service options regardless if there is a warranty or not because service is the only solution to this situation.  Don't forget to provide them the error code or 4 flashes repeating.

BRAVIA KDL-V32A12U PICTURE LOSS


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.
FIVE Blinks
AKB circuit (AKB), the timer/standby indicator blinks for about
30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. Also unit be in IK blanking,
try turning up screen slightly.

Four blinking red lights.


you can have the inverter board replaced...instead of the entire panel.
KDL 40S2010: inverter part # 178950032, you will also need 2 spacers..part # 289765511
you're looking @ 200-300$ for the inverter and 5-10$ a piece for the spacers.

KDL-46V2500: inverter part # A1251295B
you're looking @ around 500-600 $ for the part
