Question about Flat Panel Televisions
My tv does not show a picture (black picture only, sound works fine) however when you step through the AV channnels, etc and get back to the tv screen the picture does appear for 2 seconds and then goes black, (so it doesn't seem to be a problem with the display but the signal link to the display??). It did correct itself recently for about 20 minutes but went black again.
Me too! Apparently Diboss are no longer trading, so no help there. I am aware that these panels have a common power supply issue, the faulty chip is only available from China and the last one I fitted only lastest a couple of days. However the fault described above is not the same. I've checked the psu outputs; all are fine and nothing changes when the picture disappears, therefore I can assume that I'm not looking at a PSU fault. As Iain says above, it appears to be a signal link, however I have no picture on ANY input and without circuit diagrams I cannot find any component that's common to all the various inputs. This leads me to think that either the backlight, or the screen itself is faulty. I'll keep trying and if I get it sorted I will report back.
