VP280 can read but not write/erase Reply

 My VP280 can read but not write/erase. All devices work with other programmers so I know VP280 is faulty.Tried Wellon 4.3.4 (and older) on multiple PCs. VP280 firmware 9.0. All self-tests run ok and all VCC/VPP voltages are ok.
Firmware upgrade: Link LED flashes green 3 times, G/E LED is off, Wellon hangs.Tried J1 (short J1, connect USB, run Wellon) but cannot communicate with VP280. Link LED is off, G/E LED is red.
I cannot see obvious faults inside. Can you suggest any components to replace?

 I have used the VP280 to successfully write EPROMs and write/erase FLASH ROMs for many years: 27C256, 27C512, 27C2001, 29F010B from AMD, TI, Intel, Signetics, National, Spanion...
VP280 now cannot identify EPROMs, reporting ID as 00. It can still identify FLASH ROMs.
My EPROMs and FLASH ROMs (both old and new) still work with other programmers but no longer the VP280.
Wellon software can read and blank check, but not write (or erase FLASH). It just hangs for minutes before reporting failure.

 Is there anything in the VP280 that I can repalce myself to fix the problem?

I bought the VP280 several years ago on ebay and so it is out of warranty. Can I send the VP280 direct to Weilei for repair? How much would it cost to repair?

 Many thanks for the repair cost information.

I know the shipping costs to China.

But how much would the return shipping cost be to the UK?
