I would be more inclined to check the power supply board first. Check the outputs to make sure the voltage is correct getting to the inverter. You should be able to pull up specs online if the expected voltages are not already printed on the board itself.

Back light inverter is mounted on left side of lcd panel if you see it rear and subject board would be covered with some shield. Remove screws of shield and circuit board, unplug connectors and take it out. Put new board, plug connectors, tight screws.

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.

CAN YOU DIRECT ME TO EITHER THE INVERTER BOARD OR THE MAIN BOARD.


Hello Calvin,
I would suggest to change the input to a video with audio source to eliminate a main board failure.
If the back lights are not working, this could indicate that the inverter board is defective but there could also be a defective CCFL light failure.
You can find service parts in the link provided.
Let me know if you required further assistance. Search results for kdl 40bx450

Sony 52w5500 No image, No backlights, 13 and 14 blinks


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power led, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating, to many popular brand TVs and other devices. Viewing it in "Mosaic" will make surf easy.

Sony KDL-46s2010 4 red light blinks


I would suspect one or more of the miniature flourescent backlight lamps. One way to confirm this would be to power up the set with a grayscale image at 40 to 60 IRE. If one or more lamps is failing to light, a slightly darker horizontal area in the grayscale will give it away. Unfortunately, Sony will not supply any of the backlight components apart from a new LCD panel. Sorry.

Standby light blinks 13 times


Hi,
13 blinks is backlight error.. can be 1 of 2 things, 1st bad inverter board (on left side panel looking from back) it has several plug ins to the panel as it supplies voltage to the backlights.2nd could be panel itself as backlights are built into it they can't be replaced. Inverter is probably around $200 +labor, panel= buy new tv... they are outrageously expensive. Good luck!
