Question about Dell W3000 30 in. HD-Ready LCD Television
Dell W3000 lcd TV picture will usually not come on the first time power is turned on but will eventually come on after 2 to 8 times of turning it on and off. However, the sound will come on immediately and every time I turn it on. Once the picture comes on it stays on and the set works perfectly. Note that there is no consistency here. Sometimes it comes on the first time, sometimes it takes almost 10 trys.
The failure on this Dell W3000 is found in the power supply assembly, specially around the 5VDC line due to dry or leaky capacitors. Their values should be 1000uF/16 volts. If you have a capacitance meter they can easily be found when you measure the value or you can see them bulging on top.
The audio is getting Its power from a 12VDC source that is why the audio works instantly.
Let me know if you need more assistance.

FEW TROUBLESHOOTING STEPS YOU CAN TRY:
ONE: Check the line cord. Wiggle both ends near the molded part.
TWO: Make sure you have power in the outlet by plugging a lamp into the same exact outlet.
THREE: Do a hard reset; merely unplug the line cord but leave it unplugged for 4 hours before powering up again.
The whacking test is to just bang or smack the set with your hand on the back, side, top, etc., to see if there are loose connections or cold solder joints inside that are acting up. If so, the banging should knock them back to normal and the set should restore. You might have to use some creative banging and some have had to put a book or magazine under one corner to torque the chassis enough to get it to work reliably.
If this does not solve your problem then the only solution to fix your the problem is to get it repaired by a technician
