Hioki 3532-50 LCR Repair (One major problem solved, SM still wanted)
<< < (4/34) > >>

thks  an 320 by 240   pixels  glcd   wow   some high prices  there, cheaper prices on Ebay

Not being rude,   you have an expensive puppy to repair  loll 

For the touch screen, i hope  you will be able to remove the bubble,  this one i'm not even sure you could find a substitute or even an original one ??   

With so many connector lines,  i would say it's a capacitive one, But some old resistive one had many connections

To be sure,  take a pen eraser and try to do functions,  resistive will work okay, capacitive  not.

Once again, it's to find every part datasheet to be sure, 

Lots of work ahead ??

Absolute but I´m totally convinced about that it will be worth it.

Hioki provides very high quality instruments, maybe some of the best available from Japan, and they are expensive!!

Seems you've found a "Jewel in the Rough", hope you can return it to a useful life and be rewarded for your efforts  ;)

Best,

I got good hopes to fix it, but I also want to polish it in optically way after this.
I´ve payed 290€ for it, this is nothing for a 5Mhz Bridge (is it a bridge....).
It would be fantastic to get the SM or spare parts like the touchpanel or even the front.
The front is nearly yellow.... :P

Identified the chips on the controllerboard(and named them in the pic)
Actual mostly interesting is the battery control chip upper left.
Will measure it tomorrow, it controls resetting.... ;)
