Chinese CPS1 32 in 1 A-Board troubleshooting?

[ekorz]

I have a multi cps1 32 in 1 chinese that presents the following problem: the weak kick works alone randomly. What can it be?

Grab a multimeter and trace the pin back. Does the kick harness plug into the multi or the C board? Here are the pins for a c board

Pegue um multímetro e trace o pino de volta. O chicote de bumbo é conectado ao multi ou à placa C? Aqui estão os pinos para placa ac

I managed to solve the problem by resoldering pbb B and replacing two components as shown in the attached photo. Pcb apart fully functional

Sorry but what is "pbb B" ?

The correct one is PCB. just a mistake

Ah ok lol, the B board lol,
You have changed or just replace the 2 in the circle ?

My reading is that they reflowed the solder, leaving the current component in place but ensuring that it is properly soldered down by using some flux and heating up the pins. The capillary effect will pull the pins into place and pull the solder up onto them.

I soldered the entire board and replaced the components

 

[Brakvader]

You have the ref of the components ? Where did you find it ?

I have this Chinese multi cps1 with 87 games. Most games are working perfectly. Some games are already showing graphics failures. What could be the problem?
