I found a device in my bins. It seems whole and strangely not signed. Usually I always add to my database, model , the defect from which it appeared in my warehouse.
No data.
I charged the battery, I turn it on, yeah, the display is broken. I turn on the computer, look at the spare parts warehouse, there are several displays for this model. One is definitely whole. And a couple with an unmarked defect.
Despite the fact that he said goodbye to the repair of photographic equipment a long time ago. There is a database of my spare parts and a bunch of cameras.
Remember the past.
I charged the battery, the device turns on, it shines with a broken display without a picture. The lens moves normally, the flash works. The device freezes after a few frames. So the memory is full, I can’t reset it, the display doesn’t work though.
The first move I take out the battery. No memory card.
This model has one secret bolt that secures the body panel. Under the connector cover.
I always start from the right side. And a few bolts below.
And go to the left side. I turned everything off.
The case is not easy to remove. The designers decided to be a little perverted in joining the panels. I start at the back, metal and thin. Disconnect it from the tripod mount and lift it up. Disconnect the upper latches from the frame. I take it out carefully, everything is thin and flimsy, you can easily bend the panel itself and the latches.
And the rubber plug of the connector .
SO. FORGOT.
I sit and remember, there is some kind of mine, how to remove the frame and the front panel.
I twist the half-disassembled apparatus in my hands.
Carefully remove the frame. In the area of the release button it is very thin and break the plastic in this place “like two fingers obosfalt”.
Here it is!
If you carelessly remove the front panel, you can break a small pestle. This pestle controls the extension of the lens to the tele position.
Gently remove from the carcass front panel of the case. I start from the bottom in the area of the tripod mount and move it forward. Then the panel up, the release button and the pestle control fork go up.
Removed.
Here is the detonator.
And one more detonator , there is a condenser right at the top of the carcass. Approximately 270 volts. I discharge it with an ordinary 220V light bulb. Small, for convenience.
There are needles at the ends of the wires, I just pierce the insulation with them. Actually, the capacitor can not be discharged, I will not disassemble further. I only need the back of the carcass, replace the broken display. But the manuals for the repair were not written by fools, I tell you this specifically. It is written to discharge, discharge with a light bulb and I do not want to discharge myself.
I turn the carcass over on my face, there is a piece of iron with control buttons on the back panel. Below it is the display connector. Such a cunning piece of iron, on one screw and a couple of latches.
It seems simple, unscrewed it, snapped it off. But you need to make an effort, and during dismantling you can easily break the control loop from the buttons to the main board.
I twist and snap it off, you need to move the panel back to remove it from the two clips. Here you can break it.
Control buttons to the side. The display connector opens.
I snapped it open, took off the display.
Little white box, displays .
Found the right ones. < br> One whole. The second is broken, but the backlight works. I don’t throw it away, of course, there are times when the backlight goes out, the display can be disassembled and the unit replaced. The third is unsigned. We need to clarify. I am connecting.
The disassembled device can be turned on anyway, I press the button with tweezers.
No picture.
I turn off the apparatus, discharge the flash.
I sign the display. I climb into the base and make corrections.
Then I install the worker.
Clearly the memory is full of correctly guessed.
I install and snap the control buttons panel. I reset the memory and run it through all the functions.
The lens works.
Sharpens it.
The flash burns.
I drive it through all the menu items.
I take pictures, in all lens modes, I shoot the vidosik. < br> I look at what I took off.
Everything is in order, there are no more defects.
I turn off, discharge the flash.
I finally fix the control panel with latches, a small shiny bolt in place.
I put the front panel, like on a mine, on top, I try to immediately hit the zoom lever with the control lever. Hit.
I pulled the frame … I can't install the back panel.
Remove the frame. < br> Tea time.
I'm overworked, I need to rest.

When I worked in the service, I did not even stop, I did everything automatically. Nothing shorted or broke off.
Yeah, I put the frame on the back panel, I also insert the plug into place. Once and everything clicked.
I take pictures in different positions of the lens and once again run through all tests.
I left the focusing target for memory from my former life.
All tests passed, you can tighten the bolts.
Using a felt-tip pen I run along the crosspieces of the bolts.
Found some batteries in the bins.
Charged.
Wipe the display with a cloth.
Repair finished.
