How do I test the bulb. No picture.
Can anyone help me with some trouble shooting with no picture.
Fans work, I can hear the click as if attempting to start the bulb and nothing. It does this three times and then shuts off.
Pull the bulb housing out of the side of the
unit and look into the bulb, you will see that it has shattered into pieces inside.
Right or left side of unit is an access door
with a few screws, loosen and remove the housing holding the bulb.

This is tough to trouble shoot . IT might be the control or the controller. Take the remote to home depot and see if they have any fans that it works on that you can test it on. If it is the controller in the fan then you have to take the fan down and remove the controller.
Vehicle electric trouble shooting is the worst. Some of the problems you described the bulbs may have multiple filiments with only some burned out. It may sound silly but change the bulbs. Get a couple of new bulbs and try them in the different spots. Time, road vibrations and spring pressure causes the contacts on the bulbs to wear until they get a poor connection then you get a little arcing that build up a residue and a bulb that test good doesn't work.
Your on the right track with the ground wire. Try a test lamp with a good gound connection and test the different sockets, if your test light works but your bulb doesn't you have a ground fault. If neither work check the switch and fuse before you start tracing the wiring. These are just general trouble shooting tips It's very hard to trouble shoot electrical problems sight unseen.
i think the light u see is the standby indicator diode. take your tv to w/shop, the technician will know how to test the following
tube so called bulb using a different mother board card, and also test the mother board using a different tube ( tv bulb)
test the power supply out put 95 volts to the line tranaformer which will give you different voltages 5, 12 and so on.
the isolation methode will help us trouble shoot the problem, we should not be rigid on one part only.
The bulb is bad, replace it, you cannot test the bulb. You can test the inverter circuit, but you will need a service manual and the knowledge on how to work on and trouble shoot solid state printed circuit boards. Good Luck
