content: Hi all-So my hacked E30bx has a sticky shutter. It's slowly been getting worse for quite a while. And of course it sticks closed, several times a day now.I've never opened this thing. Has anyone gone inside one and fixed this before? Got any tips before I dive in? Many thanks!

content: Nobody? Please don't tell me I'm the first to go into one of these. I can't even find a teardown video to guide me... thanks.

content: Sadly I have not disassembled an Exx series camera yet. They are just too darned reliable to need my attention !This thread may assist you in the disassembly however…..https://www.eevblog.com/forum/thermal-imaging/flir-e40-touchscreen-not-working/Fraser

The FFC shutter is usually a pretty robust assembly on similar cameras and they tend to be reliable. The drive to the FFC flag/shutter arm is normally a linear or rotary solenoid that drives the arm directly or via some linkage system. Lubrication is not normally required and inadvisable in many case. Oil or grease in the wrong place can cause problems over time.Fraser

content: A quick hint in case you are unaware……If there are case retaining screws hidden behind labels, as there are on the Exx series, the adhesive is strong enough to cause damage to the label during the removal process using ‘spudgers’ or scalpel blades. To ease removal of the label it is wise to warm it for a while with a hair dryer (not a hot air gun!). The warmth passes through the label and into the adhesive, softening it, and making it far easier to release the label from the substrate to which it is attached. Do not use too high a temperature when warming the label as too much heat can cause distortion. You are aiming for around 40C to 50C at the adhesive layer. To lift plastic labels I use mobile phone spudgers, plastic levers and even a sucker ! I often use a plastic lever that looks much like a guitar plectrum. It gets under edges without causing damage, to start the label lifting process. Keep reheating the label where it is still attached as the heat in the adhesive dissipates quite quickly and it regains its grip.Fraser

They are much much better and stronger than the chinesium plectrum shaped plastic garbage, which easily will get dents on the edges. A real plectrum is almost undestroyable.

content: Pinkus,I just ordered a selection of thicknesses of Plectrum. They are the Dunlop Tortex brand.I am not that familiar with Plectrums….. do they have a thin edge as standard or will I have to sand them down a little to create an edge that can get under labels ?Fraser

content: You will have a thin edge. Since you ordered a set with different thicknesses, you are well equipped. No need to sand them down.

content: The Tortex guitar Plectrums have arrived and the selection kit is perfect for lifting labels and display plastics that are secured in place with double sided adhesive tape. The different thicknesses are a real advantage and they can be used to keep areas lifted whilst other areas of the panel or label are being worked on. Definitely something to have in your tool kitThank you Pinkus for highlighting their superiority over cheap mobile phone type “pleactrum” clonesFraser
