Dim temperature/ compass display

I have a 2005 TRD Sport, access cab (not standard or crew cab), V6, 6-speed manual, trailer towing prep package (don't know how much of this is germane to my question). Lately I've noticed that the temp/ compass display is dim. Before this I had noticed that it can be difficult to see on real bright sunny days, but lately it seems still more difficult-- and not all the time, either. So it is an intermittent problem (which I know can be a bugger to track down). When the display appears dim, it seems to get dimmer still (as it should) when I turn on the headlights. Obviously this is not a major problem, but I'd still like to know if there is an inexpensive and not-too-difficult way to fix it. Any suggestions will be appreciated.

 

This is a known issue with the solder points for the resistors on the circuit board. All you need to do is re soldier them. Should be a few videos on youtube for this exact issue.

 

When I bought this truck (a little less than 5 years ago), that display puked. I found out then from this forum that the resistors were the problem; soldered them, problem solved. I wondered about them when this "dim" display problem came up; I would have thought the resistors would either kill the display completely, or leave it full bright. So, I learned something. I'll have to get to soldering them again. Thanks.
