Narrative:

Enroute I identified a mechanical defect on the LCD (liquid crystal display) display of the captains VOR/DME (omnidirectional range/distance measuring equipment) control panel on this aircraft. I entered the item into the ACARS reporting screen and sent it. We left the aircraft at customs and I assumed it would be fixed. Unknown to me at the time; the mechanic who addressed this defect signed it off as a 'false discrepancy'. I simply cannot understand this as I clearly described the defect; where it was located; etc.the next day; I was scheduled and did fly the same aircraft. Shortly after arriving in the flight deck; I noticed the captains VOR/DME panel was still not repaired. I looked at the log history and found the mechanic previous day (don't know who it is); did nothing and signed it off. I entered the item again; and called maintenance.[maintenance] came to the flight deck; looked at it; and informed us that it was indeed defective; and was not deferrable because it was powered by the standby bus. It took them about an hour to procure a replacement and defer a wheel well fire indicator; they did a great job. Generated the mrd and we left very late. However we arrived a few minutes early in [destination].I can only find two explanations for this.either the mechanic who signed it off on the [first date] was either intentionally signing it off without repairing it; or could not locate the item; and was looking at another LCD indicator and found it normal. In one case this is a training competence issue; the other an attitude of non compliance. Both of these are disturbing to me as a pilot. Also interesting is that the aircraft was flown to [country] and back between the two flights I operated it; with no report then either.after it was properly repaired; we departed.it is really all too unfortunate that the mechanic who signed this off on the [first day] did not repair the defect when the aircraft had 3 hours of ground time.because of this mechanic; we incurred a lengthy delay; and then had to burn thousands of dollars of extra fuel to get our passengers to [destination] on time.so; in conclusion; not only did this caused a lengthy delay on the [second day]; caused many dollars of extra fuel to be burned that would have been unnecessary; but also generates an incident of non compliance with the federal air regulations that most likely needs to be self reported.
