content: HI all.its my first time posting in here, a bit off my backgroud i have a bit off knowloage in fixing a laptop but i have never try fixing a theremal camera before, in my banch i have multimeter, banch power supply, hot air gun , solder , thermal cam, and a microscopeso my collage compony plan to sell their flir e75 with full accessories and the hard case for only 300 usd. the catch is it been submerge before and currently are not working.i have no idea how deep or how long it got submere for, do you think i should take it and gamble to fix it?, i plan to "upgrade" this to flir E95 if successful in fixing it,my concernis the calibration will be a mess will that be the case?

content: Good Morning MARCEBELE, No one seems to be able to give you an answer, so I will give you my opinion. It is a $6,000 device, according to Google, and $300 is a GREAT price if it is possible to repair it. Details of the water submergence are unknown, so it may be bad and irreparable damage may have been done. Or, it may just need a good drying out. This is a BIG gamble and you may wind up losing your money. Or, if you can't do anything with it, maybe you could recoup some of your money by selling it on Ebay, (but be up front with the condition).Good Luck and report back with your experience.

content: Welcome!You will be taking a gamble. Even if the sensor has not been damaged by the water, you could face other problems which are equally as bad. If the microprocessor on the board, or its program memory have been destroyed, it is unlikely you will be able to get the firmware needed to flash a replacement.It would be a great buy if you can repair it, but you could also end up with some 300 dollar e-waste.

content: Quote from: MARCEBELE on November 12, 2024, 06:16:25 pmIs that even possible? I would assume a completely different sensor seeing as the E75 has 320x240 resolution and the E95 has 464x348.I can't imagine the E75 hardware or firmware supporting a different sensor. Even if that is possible, any existing calibration would, of course, be meaningless if you change the sensor.

content: Provided there's no residue or residual water and you can get it working, I don't see why the calibration would be thrown off. I don't believe the optics or coatings are hygroscopic, though they may be degraded by a bath and the residue left.If you're lucky, the battery circuitry got cooked (or similar) with little water ingress and your repair doesn't have to be substantial. If you're less lucky, you'll probably have to disassemble and clean the whole thing in addition to repairing (maybe optics included, if there's humidity between lens elements or similar). If you're unlucky, there's enough damage or corrosion to make the amount of repair time and parts required to get it even to a point of basic functionality is significant and maybe not even worth less than a used one.

content: If the device had the battery plugged in at the time of the accident, and especially if the battery was not immediately removed, chances to rerstore are very slim. If you ever seen water damaged cell phone boards you would know.

content: Update on thisI end up didn't got this, another person buy it first.Could be a good gamble because it still look so good what a shame,I'll be around In the future to try learning more in software and hardware design and troubleshoot side off thing.Hope to learn alot

content: Oh. Bad loss. Even the accessories would make more than that. Sorry.

content: My workshop flooded a year agoI had an E4 in its case (closed) which was submerged (battery not installed). There is an internal battery on the main board, so there was a lot of electrolysis damage. The battery was damaged, water got into the thermal sensor and into the LCD (between the glass and light guide layers) it was a mess, I managed to get it going again but it crashes after about a minute. The visible light camera does not work anymore.Surprised the storage case wasn't gasketed like a pelican case, a bit of an oversight IMO
