CPS2 B ERROR IN THE GRAPHIC

[WRF77]

Hello, could anyone help me? I have a B board with a graphics error, as shown in the video. I've already done some tests, like testing other roms and maskroms, changing PAL's. I tested with the rom tester and there was no error.

Simple answer first: a poor connection between A and B boards can cause CPS-2 graphics errors. Make sure there’s a good connection between boards, e.g. ensure there’s no gap and use the case clips. Try cleaning the connectors; Deoxit works wonders.

Verifiquei a conexão com a placa A e já testei em outra placa A. E o problema continuou na placa B.

Resposta simples primeiro: uma conexão ruim entre as placas A e B pode causar erros gráficos no CPS-2. Certifique-se de que haja uma boa conexão entre as placas, por exemplo, certifique-se de que não haja folga e use os clipes da caixa. Tente limpar os conectores; Deoxit faz maravilhas.

Looks very similar to what I had on my Xmen cota when I first bought it, I bought with this problem, tried cleaning the contacts but nothing, took the b board apart and found one of pcb support feet near the connector was broken and missing this seem to be quite common on these boards I've found many cps2 b boards with loose snapped support feet so of couse when the b board went back in the PCB was bending upwards and not clipping into the motherboard, contact leaner does wonders for these connectors, I've had a couple poor condition cps1s with dodgy connections, cleaners sorts them out.

Parece muito parecido com o que eu tinha na minha cota Xmen quando comprei, comprei com esse problema, tentei limpar os contatos mas nada, desmontei a placa b e descobri que um dos pés de suporte da placa perto do conector estava quebrado e faltando isso parece ser bastante comum nessas placas, encontrei muitas placas cps2 b com pés de suporte soltos e quebrados, então é claro que quando a placa b voltou para o PCB estava dobrada para cima e não encaixava na placa-mãe, o contato mais magro faz maravilhas para esses conectores , tive alguns cps1s em mau estado com conexões duvidosas, os limpadores os separam.

Obrigado pela resposta. Consegui consertar o defeito, apesar da eprom de teste não apresentar erro de ram do objeto, após trocar as ram do objeto funcionou normalmente.
