Hello I am rick and new
The system listed above is not the one I am having problems with, my problem child is a emachine w3052 ive had for a long time, it runs xp home SP3 and the monitor is a Pivilionmx70........Here is the issue, It has always ran fine, I had it unhooked for a few weeks and set it up and the monitor would just go to green light for a second then back to yellow, no mouse-no keyboard, I noticed that the socket on the back seemed loose so I opened it up and observed the one portion I could see and wiggled the socket and it was moving the pins that penetrated the board. At this point I figured that I would need to get the board out and perhaps resolder the connection if it had broken free but mainly secure the socket some way.
Well just a laugh I started it up and it worked fine so I used LapLinkMover to move my data to my win7, all went well, now the next day nothing SOS. When I move the plug in the socket the green light comes on but still no image other than the floating message saying CHECK VIDEO CABLE CONNECTION only when the light is green, still no Mouse-no Keyboard.
I have tried a different monitor and the same thing happens. I would like some guidance on how to do some preliminary tests and hear what others have to say about this.
I hope that was enough information. Thank's , I look forward to your reply.............rick

 

This is rick
Thanks for the reply, to answer your questions, Yes I did get the board out and will need more magnification to actually see the joints , just had eye surgery,however , I was able to rest my finger on the back of the board and could movement. The next step for me is to secure the board and have someone else move the socket while I have my finger on the board." this will disconnect my mind and left hand from right" then I will try a Loupe to look at it, I will surely let you know.........
As for the age, I will look right now. . .ok the silver label on top of board says, Phoenix Bios PentiumIV PHOENIX 2001 003362842.....lower left corner of bd. is, 1.1MO480020. ( I think you are right FLORIDA !) 2006
Seeing the solder joints again they do look light just on that one set, like a different BOT or body installed it ?

Thanks again flavallee and Blues_Harp28 you have very good taste in music !
