Im an electrician and not afraid to tackle a repair if its possible but if its not or not worth it, I guess Im looking at a complete replacement?
T5 fixtures are fluorescent fixtures. T5 simply means that the bulb is 5/8" in diameter. The fixture is designed for the wattage of the bulbs. If you put higher wattage bulbs in the fixture it may overheat possibility causing a fire. As long as the wattage of the bulbs is within the design of the fixture you would be safe just putting in new bulbs. You should check the starter by putting a new one in or two if there is a separate starter for each bulb.

The fixture is very simple. Sheet metal (the housing and reflectors), the ballast (basically a voltage changing item) the mounts for the bulbs and the starters and their mounts. Most of the fixture can be changed piece by piece for troubleshooting activity. The only soldering needed may be in the substituting of ballast. You can't substitute any other T rating bulb for the fixture T8 or T12 will not fit.

There are LED substitute bulbs which are composed of LED chips put in a fluorescent bulb type bulb frame . I don't know anything about them so I can't say how good they are or how easy they are to use, sorry.

Nobody's life, liberty and happiness are safe when Congress is in session. Hallyx kindly reminded me that this statement is attributed to Mark Twain. Even more pertinent today then when he said it.
