Check connector between Logic & PSU 2nd pin from Left (Vs_ON) for DC volts.
If Voltage is 0 then problem is with Logic or SSB.
If Voltage is 3.1 VDC then problem is with PSU or other PCB's on Panel.
On startup Logic checks for errors and also polls the SSB for Errors. If Errors found then Logic will not send High to PSU.
To confirm if SSB or Logic is at fault then disconnect and remove SSB.
Use 2 Jumpers to short J8003 & J8004 on the left edge of the PSU
Use 1 Jumper to short CN2012 on the lower left part of the Logic PCB (White signal to the Display).
Plug in the AC to the PSU thru CN8001.
If PDP panel operates with White field screen then problem may be the SSB.

You gave too technical an answer . I'm 80 years old & don't know what you are talking about.


Assuming you have a TV hooked up to some kind of cable box, I would venture to say the TV is telling you it is not receiving a signal from the cable box.
Two things could be the problem;
1 You are on the wrong channel to receive a signal - some boxes send the signal to you on channel 3 - if your TV somehow got changed to channel 4, for example, it would not recognize the signal from the box. Make sure you are on the correct channel setting.
2. The cable box may not be turned on or formated properly. Turn the box off and then back on after a few minutes. Follow any messages on the screen on the box for a proper start-up.

If nothing helps, call your cable company for assistance..

When i turn on my screen it says no signal and turns off


Either the "data" cable between your screen and your desktop is defective, or that cable is not connected to your screen, or that cable is not connected to your desktop, or the video-card inside the computer is defective.

Check the connections.

Temporarily connect the screen to a different laptop/desktop computer, to see if the screen still works.

Temporarily connect a different screen to your desktop, to see if your desktop's video-adapter is working.

Sony kdl-40v5100 has handshake problem


1.This issue sounds as though the TV connection circuit has an issue.
2. You have changed the DVR and the HDMI cables and you still have an issue with the video (pink screen) indicates a video circuit issue ( improper voltage or current) at the video section of the circuit.
3. This will require some troubleshooting by a qualified tech.
4. To make sure, try connecting another properly working LCD TV to the cable box or DVR an check.If you get a picture and sound properly it is the TV.
5. Usually a cable box is QA'd (quality assured) by the company and will not be sent unless tested 1st

Select Language


With electronics sources or monitors,asking a language preference is a first or early step in initial programming.To analyze the source of the "which language " request--dis-connect the cable box temporarily and hook up signal direct to tv.If ? is still there,the tv is asking it. If ? is gone,then the source box was asking. Any further assistance needed,please let me know.
