Hi...

No issue at all with replacing them other than getting the new one to fit where you want it. Sometimes this takes woodworking for example.

If you are looking at new sets, suggest getting a LED/LCD set vs just LCD (which uses florescent tubes.) 4 pros for this...

1) LED's can not really be broken with the coach movement, very durable. (you are more likely to crack the panel glass than break an LED).
2) Lower power consumption thus allowing you to dry camp longer. (If you do that. Every little bit helps.)
3) LED's do not start to dim out over time that would really be perceivable like a florescent tube can.)
4) LED's produce a better quality light.

Side note...some people confuse LED with being an LED set. It is, but the LED is only used as the light source. The image is still produced by an LCD panel . So really you still have LCD and Plasma flat panels to choose from. But the LCD comes in two flavors, LED and florescent for the light source that needs to show though the LCD panel to produce an image.

Have fun.
