That's correct it is the LCD panel. This is actually a common problem with this model, and its surprising that it really does look like a video board (BM board) problem. It is actually a problem with the panel itself.
Here is the fix:

This guy was kind enough to post it. I recently did the repair on a KDL-32M3000 and it worked like a charm. Took surprising long, but worked like a charm. I didn't have a 10 Ohm resistor laying around, so I used 2 x 4.7 Ohm resistors in series.

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 Bravia KDL-xbr4 Replaced TCON board All worked great for a week Had an issue w/ HDMI cable at the box fixed it and now tv comes and the goes off to 6 blinking red lights


6 red flashes- backlight issue, bad main board, or power board or inverter boards- check standby volts on power board. "backlight on" volts should be 3-5v from main logic board then 24v to inverter


Have this from a youtube link find BUT
Better is to look first also on bad leaking or bulged capacitors thats better to replace in the bad components to get a repair because active components died on bad capacitors but after a while because on the build-in protection circuit by faults like deformed or leaking capacitors and even several fuse resistors then after replace a complete board again after a while you will may be get the same kind of problems again, take If you find some or much bad capacitors replacements 10 volts dc higher . begin with control on the power supply first of all.

0ne of 3 has failed:

Please seek the expertise of an experienced TV repair technician - as they contain potentially lethal voltages that must be properly discharged before work can begin.

Screen dark but can still see picture


could be a problem with the inverter board which is the power board for the CCFL backlight system. if the tv doesnt actually go into shutdown you may be able to still see the video but it will be very dark no glow to the screen at all. the reasons for shutdown for inverter failure could be a bad inverter transformer or open fuse on the inverter that supplies power to the board or it could even be a bad CCFL lamp. i suggest looking for the fuse that is the most likely suspect it may be yellow if i remember correctly. good luck

My Sony KDL-32M3000 has dark reddish picture, checked the ribbons around the frame they're ok, power supply is ok, Hi voltage board is ok, I'm guessing the main video processing board since I don't have a...


It will be either BM board (Video Processor board) or Tcon Board (top side of panel). I have similar problem...my TV turns on, lamps turns on (you can see them from back side panel holes) but just a dark blue picture appears with no image (like picture when external input is selected without signal), no OSD appears....some times I can heard audio (using Antena).
I'm thinking getting the BM board.

Logic board? Are you referring to the Main PCB (BU board I think). This issue is caused by the Timing Control board (T-CON). It’s the board directly on the panel that connects by LVDS cable to the Main PCB. Not sure if it’s a part you can purchase separate from the LCD panel, but give it a whirl… you never know. I hope this was of some assistance.

I have a sony 32m3000 color is dark and red also


@circuitworld: You claim in your profile that you repair plasma and LCD TV's, but you just told someone with an LCD to replace the convergence IC's and linear buffers. First off, convergence IC's are in rear projection TV's not LCD's, and the buffer boards are in plasma's, again, not in LCD's

@gardenwc: Typically what you are experiencing is a bad video controller or an actual faulty panel, the latter of which is not cost effective to replace.
