Ok , received this machines somethime ago . we had seen gpu wa faulty , since was not displaying image , and after giving 15 second of heat on the center of the chip it start giving image . so we talked with client for chip replacement , and since he had urgence , we made a good reflow on is machine for it can work with the machine until chips arrive . well 2 days before chip arrive machine not giving image again , and we mentioned to him , well chip is almost here , leave machine here and we will replace it very soon . chip arrived , we inserted the new chip , all seems good , passed all test .
client started using it , and it worked good for maybe 3 weeks , it came in saturday , mentioning machine was not displaying image , only somethimes and will the tipical problem of VRAMS ( red lines ) . i thinked could be vram gave a bit of heat on all of them .. and internal display not displying anything now . only external and with the suposed red lines , and some flicker..
lifted all vrams , and reball them but the same , so i replaced with another vrams , but still same issue as well .dead chip ??? but dam is a new chip working for a month .
