    Sony kde-42xs955 No video

    Ok so I just bought this Sony Wega kde-42xs955 for $10.00 couldnt pass it up, there was no info on what was wrong only told that the screen doesnt turn on. When I got it home I plugged it in and it powers on with a flashing green led 11 times and the lights stay on like its good but the screen does not light up or come on. My question is where do i begin to find out whats wrong? I cannot find any bad caps or burned/chared components btw. I have attached pictures of the board.

          ok I believe I have narrowed it down to the Y-sus, How can I find out what to do to try and repair it, I have MMeter and Soldering Iron in hand!

              Does this TV have a Y-sustain? It looks like an LCD TV, not a plasma TV. Unless the main boards are under that cage. I suppose, PSU is quite big for an LCD.

                      I have aqquired one of these, and what mine does, it turns on and I get pix & sound for about 10 seconds. As soon as the fans start it shuts down with no error codes. Any ideas?

                          All in one Sony Vaio VPCL22Z1E 3D version no video on main display
                          by microso
                          Hi,
                          I bought an all in one Sony Vaio VPCL22Z1E 3D version which does not show anything on the display, instead it works ok on the hdmi output (video and sound).
                          I tested with a flashlight and it seems that it does not display the image without backlight.
                          It doesn't make any sound in the built-in speakers and the headphone output has a very weak level.
                          As an observation, I use a 19.5V power supply with 120W and in the specifications the original one would have 180W.
                          Could this be the reason why it doesn't work properly?

                          Sony STR-DN1050 - No video, no BT, No WIFI, and FM is not changing stations
                          by jason123
                          Hello folks,
                          New to Audio equipment - I got this receiver, I connected speakers and I tried to connect to Bluetooth. My phone would not see the receiver (Receiver flashes the BT as if it's trying to pair). Then I put it on FM radio, I get white noise on the speakers. I click the +/- Tuner button, and it moves from saved station 1 through 28, but the frequency is 87.x MHz not changing. At this point, thinking I may need to do a FW upgrade, I connected an HDMI cable to the TV and TV reports "No Signal" - TV "Kind of" sees the receiver (When connected to greyed out port,...

                          Sony GDM-FW900: Help me diagnose why it won't turn on? (Video included)
                          by jrodefeld
                          Hi everyone,

                          I have a vintage Sony GDM-FW900 crt monitor that I really enjoy using, but it has developed a problem and won't start up.

                          This unit was completely serviced a few years ago by Unkle Vito in Los Angeles and it fully passed all tests, was factory calibrated, etc. There was a faulty part (can't remember exactly which one) that was replaced at another repair shop about a year ago. Other than that, it's been working great.

                          I just say all that to say that this unit is probably in pretty good shape since it's been fully serviced and checked recently....
