When an lcd panel is very dim and brightness adjustments don't help what componet is likely to be the problem?

LCD monitors use a back light to generate the light needed for the LCD panel to operate. In most monitors, the light source is a cold cathode tube or several of them. As the tubes age, they tend to get dimmer. That is probably the most likely cause of the problem but it may also be the power supply that drives the tubes, known as an inverter.
There are other possible causes but the back lighting is certainly the first place to start looking.

When an LCD panel is very dim and brightness adjustments don't help what component is likely to be the problem?
The inverter. The inverter converts DC to AC used to power the back- lighting of the LCD panel. Check with the notebook manufacturer to confirm that it makes sense to first try replacing just the relatively inexpensive inverter board before you replace the more expensive entire LCD panel assembly.

Could you bend a valve when putting a new cam in if you don't loosen valve adjustment?
If your valves are way out of range you could contact the cylinder head or the piston and possibly bend the valve but it isn't likely they would be that far out of range. If you have hydraulic lifters you shouldn't have that problem. With solid lifters, be sure to slacken all of the adjustments.
