SOURCE: Wharfedale TV power problems
got a 32 inch wharfedale tv from argos also and it seems to boot up and then shut down and just loops, if i keep unplugging it i can sometimes get it on but with a high pitch wailing, only 15 months old, gutted!

This could be your power DC.
I had the same trouble when I set the tv on its start normal.
but after a few min. the screens falsh on off, on off.
I change the adapter and the problem is solved!
Check this with a other DC power adapter.
I hope this will work. But for me it was the power DC adapter.

SOURCE: blue light flashing
Possibly the power board or the sustain board has died.
Power board failure does not stop the blue light from working as this is an LED on voltage side of power transformer. The set fails because it has detected a voltage difference in one o0f the other boards that controls the initial starup and convergence. Some transistors and capacitors are also possibly involved. Not a dIY unless you are skilled. Parts $300 labour ?
but about $400
If you are a DIY get a kit from this site, complete with step by step instructions This is an LCD rear projection set.The yellow blob may be from the drivers to the LCD display, dirt or object on the projection mechanism, stain on the mirrors or lamp; bad projection lamp - among others.If you are handy, get inside the set and see if you can observe any of the items mentioned above.
