it is not a good sign. If the tv screen is dark (no picture) and no sound but the standby red light is continuously blinking then it could mean the power supply board in tv is faulty.
Usually a few burnt out capacitors on the board but hard to replace yourself unless you are experienced in this sort of work. From the model it appears a reasonably recent unit and you may want to get it checked out by a repairer at least to get an estimate of the cost.

From some of the forum threads I've read about this, it seems like there were early issues due to bad firmware, but they have all be resolved with the recent updates. It also appears to be very easy to replace the hard drive. Just swap it out, format from the menu and you are done.
Buy a new tv.The tv u have now,the LCD screen panel it internal screen membrain is broken.The tv,u have now,dosen't worth a whole tv anymore.Tv only now,worth as only as a salvages tv for it electronic boards for parts,that it.The LCD screens panels are 90% important to the LCD tvs,when,that damages or broken.The tvs doesn't worth it to replaced it LCD or Plasma screens,because tvs screens panels are limited produced by the tvs industries,u will not able to buy it anywhere,but the tvs industries themselves.They'll sell it to u,but the same priced as a new tv.
The problem can be caused by a bad sustain board (Ysus Zsus) , the popping sound is often caused by a capacitor blowing up. The TV must be taken apart and tested before eventually replacing sustain boards.
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.
Sounds like your component cables may have come off its contact point. Check to see if your cables have become loose. Pushing them back in place should take care of that but check at the source output and the TV's input. Red Green Blue, when ever one of these 3 come out of contact the TV will produce a color hue relevant to what color remains in contact, looking faint and discolored. If you do find a loose cable connection, inspect the contact ends and squeeze lightly to restore a snug fit but don't do it to hard or you may damage the prongs.
