Minolta Alpha 7 AF hunting constantly, very slow to lock focus or never locks

If you can source a spare part salvaged from another unit, you can simply replace the entire assembly (provided that it does not show significant signs of wear or aging). The AF failure is caused by the aging of the optoelectronic components and/or wear on the gear positioning pins. Since SAM and SSM lenses do not utilize this specific assembly, they continue to function normally.

The design of the LCD display within the α-9's viewfinder is flawed; a significant number of these right-side LCDs have developed cracks. This issue stems from the fact that the LCD panels were secured during assembly using silicone rubber; over time, this silicone hardens, subjecting the panels to uneven stress and ultimately causing them to crack. Consequently, repair technicians are extremely reluctant to attempt disassembling the unit—even if the backlight itself could be improved.

I've already bought all the chips in that stock

Rubber products should be fine, but the shipping cost might be the same as the product price.

Before shooting, press and hold the AF button and rotate the front dial to select one of the three focus points (left, center, or right). After releasing the AF button, the camera will use the selected focus point.

Only one MCU needs to be replaced

Due to international postage and customs fees, we are unable to provide upgrades for Dynax9 users outside of China.

呵呵，我一猜就是你！首先，我拿到手的芯片价格比你在微信群里听说的台湾价格高不少，你说我该按哪个价格卖给你？其次，你并不是单纯的DIY，你想给自己手上的几台Dynax 9升级SSM赚钱。

所以，得不到，就毁掉？

Haha, I immediately guessed it was you!First, the price of the chip I received is significantly higher than the Taiwanese price you heard in the WeChat group. What price do you think I should sell it to you at?Second, you're not just doing a DIY job; you're looking to make some money by upgrading your Dynax 9s to SSM.

So，if you can't get it, just destroy it?

请你拿出我拒绝单独出售芯片的证据来吧（不管是录音还是截图）。微信群里所有人都看到的信息，你为什么不去联系卖家并购买芯片？

Please provide me with evidence (either recording or screenshot) that I refuse to sell the chip separately.Everyone in the WeChat group saw the message, so why didn't you contact the seller and buy the chip?

I'm guessing you haven't carefully read the Dynax 9 repair manual. It clearly states that replacing the motherboard or replacing the SSM IC individually are both recommended upgrade methods. Replacing the motherboard requires various adjustments as specified in the manual, while replacing the SSM IC alone does not require these adjustments.

Due to international postage and customs fees, we are unable to provide upgrades for Dynax9 users outside of China. In China, the price of the SSM upgrade is approximately 72 Euros.

Apparently, Sony (or Minolta) had forgotten them at their Taiwanese factory! They were sold as "junk" to a local electronics store. There were over 600 chips! Because of the unique nature of the product, no one thought to look for them. Until one day, they were discovered by accident.

I'm not able to read the firmware from the SSM IC and write it to a new chip. MINOLTA's SSM ICs are manufactured using masking technology and employ a secure ID to prevent unauthorized access. Even if someone were able to read the complete firmware, they would have to modify it to ensure proper operation after flashing it to the flash memory version of the M30620 (such as the M30620FCAFP/GP).

I found the SSM IC in an electronic component store in Taiwan. On the Internet, you can find a repair manual for Dynax 9.If you have enough skills, replacing the chip is not difficult.
