Como está o consumo dela na assimetrica?

Nao . essa linha, tem que estar com alta impedancia. se tiver curto, o problema está nela. vai ter que injetar uma tensao aí. pra ver se acha quem consome a mais

verifique os 2 lados do R198

c232 nao deve ter 5v, ele precisa de uma tensao de habilitação (por volta dos 3v3)

@wjinformatica vc precisou editar o serial e colocar o original do gabinete? ja instalei uma clear me, e nao resolveu. placa intacta. sensores todos ok

Estou com esse equipamento na bancada, que veio de outra assistência, com charge queimado e sem o chip da bios. instalei novo charger, novo chip da bios e a maquina subiu vídeo, porém com boot extremanente lento. olhando na internet, vi que essas placas tem relação entre a Bios e o smc, que precisa "casar" para o perfeito funcionamento. achei que fosse apenas o serial, mas nao funcionou. Abri o arquivo de bios, limpei a me, editei o serial, mas continua lento. pergunto se algum colega ja passou por isso.

Monitore PL3 e PL4. Verifique se no momento do start, sobe alguma tensao nelas.

Provavel fonte incorreta. esse aparelho, funciona bem com a fonte original de 20v.

@CJ boa noite irmão. Qual foi o link do melhor custo benefício microscópio e câmera que vc comprou?

Boa noite. Remova esse link externo do seu topico, pois é proibido. +lcdvdd tem que medir 3v3 foque no QV4 pra começar, diga as tensões dos pinos 36, 37 e 40 do conector lvds (com a tela conectada)

colega, Estou muito pegado esses dias.nao consegui parar para fazer o video procre esse titulo no youtube vai ser o primeiro video a aparecer. passo a passo. segue: How to install ASD Apple System Diagnostics

corrreria. faço hoje. quem sabe o nome do programa que grava a tela (for mac)

Parabens pela perseverança! aconselho remover o link externo, para nao ser advertido.

É bastante simples. Não tenho habilidade pra fazer vídeo. Mas vou tentar fazer um e postar aqui.

nao é o mesmo. ASD tem diagnosticos mais especificos, e codigos de erro, o AHT, é um teste de usuario mesmo, pra facilitar um diagnostico por telefone por exemplo, para o serviço autorizado apple. (nivel de usuário).

Apple Service Diagnostic. aplicativo utilizado por engenheiros (ou tecnicos) da apple, para fazer o teste mais especifico para diagnosticos exatos. ele testa inclusive os sensores de cada placa, informando falhas se encontrar. ferramenta indispensável para reparação de apple. segue exemplo de um erro que peguei hoje aqui. fui na área desse sensor, e tinha vestigios de derramamento de liquido. ressoldei tudo, troquei 2 resistores que estavam com aparencia bastante ruim, e tudo ficou nota 10.

Boa tarde, se inicializa, e depois vai pra tela branca, pode ser GPU falhando. típico para esse modelo tente passar o ASD para diagnostico mais especifico

Colega, Fica muito mais fácil e rápido, diagnosticar lentidão utilizando o ASD para o seu equipamento. geralmente, lentidão em apple, é causada por mal funcionamento de sensores. O ASD, ap onta certinho o sensor que está falhando, daí´é só fazer uma verificada na área dele.

Colega, nao me lembro direito qual a voltagem de saida dessa placa. faço muito pouco placas de impressora aqui. mas geralmente, esse curto é no primário, na primeira fonte de 5v. a lampada, é ligada em série com a entrada de tensão AC da placa, evitando assim a queima de componentes por curto ou baixa isolação interna

muito bom parabens!

Verifique o regulador da alimentação de memoria, se estiver bom, flash mesmo.
