Sorry to inform you my freind, but the main board has to be replaced in this beast. Could get expensive. there are no schematics and or componets listed to repair this module. Its a board level repair only. Try going to ptscorp.com, find their phone number, and see if they repair these boards. if not you will need to contact the manufacturer for replacement boards. good Luck Please do not forget to rate this thread.,

If it is a LCD TV, and there is a faint picture, it is probably the backlight or inverter board (probably the latter). This is a common problem (especially with PC monitors).
Do an internet search for your model and inverter, you may be able to replace it.
Make SURE you REMOVE the power lead before opening the set !!!!

SOURCE: DIBOSS tv shows no picture
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.

This unit should still be under warranty and should be taken in for warranty service. Any attempt to access the interior will void the warranty. It is important that a complete description of the problem like you entered here be taken along when you bring the set in for service. This will insure that the servicer be able to reproduce the problem and resolve it.
From your description (and as a servicer), I would be looking for a component that is heat sensitive. These types of problems are fairly easy to locate and resolve.
Please take this in for warranty service and update this when you find out the details.
