Question about Sony BRAVIA KDL-40S2000 40 in. LCD HDTV

Sony Bravia 46S2010 no picture only glows but, only sound on

Hello, I need help! someone that's an expert regarding my Sony Bravia 46" LCD 46S2010 (manufactured 11/2006). I have this strange problem with the LCD panel. The TV powers on, no trouble red lights, the sound is on and clear, but I don't get a picture. I can switch channels by hearing it, but there's no menu on the screen. I only get a low glow from the LCD backlight which I can see it slightly flicker as I switch the menu button.

I have a broken screen Sony Bravia 40" LCD 40S2010, and this TV works fine, except it has a cracked LCD. I can still see snow flakes, and distorted image coming on the screen. I open the 40S2010 and all the components internally matched, except the LCD controller board, and LCD inverters, because the screen sizes on both units. The 46" has TWO inverter boards on each side, and the 40" has only ONE on the right side.

So, I swapped the power board, all the audio/video components, but I still only get the low glow, nothing on the LCD, but there's sound. It's the same problem. Can anyone tell me what am doing wrong, or am I missing something? Or how do I know if the LCD panel is bad? If the power inverters on the 46" is bad? Please help, thank you in advance!

    Thanks for your help bucdon!

    I was thinking about replacing the inverters boards, but from what I experienced. If the inverter boards are bad, the TV fails to power on, goes to stand by, and the red lights starts blicking. What do you mean by Tcon? and attack to the panel? thanks!

ON THE VERY TOP OF SCREEN, I HAVE LINE WITH "NO SIGNAL" ON LEFT SIDE AND A NUMBER 3 ON THE RIGHT SIDE. ANY SUGGESTIONS


You might just need to press the source button on TV remote so a box pops up on the screen giving you options like tv,hdmi1,hdmi2 or av1,av2. Hopefully its a little helpful.

Plasma has a problem that if you do not use it for even a short period, the liquid inside the layers of the screen will get hard because of cold , it needs to be running or in room temperature. so kindly get it repaired by a TV expert if that's the problem , then you have to buy a new plasma..

Try plugging the coax directly into the T.V. or from you VCR or DVD player then to the TV. The bravia sets also have various picture mode settings as you will discover when you go through your manual. Cable boxes or splitters can cause problems also is they are not of good quality. I love my 40.
