Computer Monitor Problem
This is an old 13" SVGA monitor. Last week my computer died.
Apparently the motherboard fried. The computer got slower and slower for several days in a row and then it would not boot at all. The harddrive is fine. I had another used computer and put my HD into that computer. That worked fine. Whether this is coincidense or fact, I am not sure, but right after that happened, my monitor started acting weird. When I turn it on, the computer boots up and everything is fine. About 5 to 10 minutes larter, the monitor gets very dim. I can barely read it. Shutting it off does not fix it. However, a good smack on the side of it with my fist gets the monitor back to normal viewing. Sometimes I have to hit it several times before I can see the screen again. After that, it stays working just fine as long as I dont shut it off. However, I have noticed that it occasionally gets slightly dimmer, but is still usable. The brightness and contrast knobs are turned to max brightness and they do nothing when the screen gets dim. Since this is the only monitor I have and can not afford another new one now, I just have to keep beating on it or I cant use my computer. I plan to begin looking for another used one, but for now, this is all I have. I have puttered with electronics all my life, so I am not afraid to open this thing and I know what to keep my hands off (high voltage wire to CRT). Anyhow, I am not going to spend any amount of time on this. I know there are millions of these old monitors around looking for a home, but until I find one, is there anything that I might check? A loose solder joint seems like a possibility, although I really dont know how that could have developed after all these years when I never move the monitor. I should mention that jiggling the cable from the computer does not solve these blackouts either. Anyone have any suggestions. Thanks Mark |

Huh? You can't afford a replacement monitor? You can pick up good used
17-19" CRT monitors for $10 a pop at used computer stuff type stores. JR wrote: This is an old 13" SVGA monitor. Last week my computer died. Apparently the motherboard fried.

We can't give the bloody things away. I have 5 near new 17" monitors hidden to stop the boss from dumping them in the garbage. -- ++++++++++++++++++++++++++++++++++++++++++++++++++ ++ + Required crap appended to avoid restrictions imposed by brain + + damaged idiots. + + Server Response: '441 Posting Failed (Rejected by POST filter)', + + Port: 119, Secure(SSL): No, Server Error: 441, + + Error Number: 0x800CCCA9 + ++++++++++++++++++++++++++++++++++++++++++++++++++ ++ |

You're talking to someone who repaired IF transformers in old tube sets, hand rebuilt broken appliance parts and who repaired small appliances like popup toasters, steam irons and kettles for a living. But even I have seen the writing on the wall. -- ++++++++++++++++++++++++++++++++++++++++++++++++++ ++ + Required crap appended to avoid restrictions imposed by brain + + damaged idiots. + + Server Response: '441 Posting Failed (Rejected by POST filter)', + + Port: 119, Secure(SSL): No, Server Error: 441, + + Error Number: 0x800CCCA9 + ++++++++++++++++++++++++++++++++++++++++++++++++++ ++ |

The solution is in there if you're willing to do a little work on your own. --- sam | Sci.Electronics.Repair FAQ: http://www.repairfaq.org/ Repair | Main Table of Contents: http://www.repairfaq.org/REPAIR/ +Lasers | Sam's Laser FAQ: http://www.repairfaq.org/sam/lasersam.htm | Mirror Sites: http://www.repairfaq.org/REPAIR/F_mirror.html Important: Anything sent to the email address in the message header above is ignored unless my full name AND either lasers or electronics is included in the subject line.

But even I have seen the writing on the wall. So we shouldn't repair anything anymore and clog up the landfills at an every increasing rate? Sure, it doesn't make sense to pay $100 to repair a monitor not worth $10. But, if he is able to check solder connections and restore it in a few minutes? --- sam | Sci.Electronics.Repair FAQ: http://www.repairfaq.org/ Repair | Main Table of Contents: http://www.repairfaq.org/REPAIR/ +Lasers | Sam's Laser FAQ: http://www.repairfaq.org/sam/lasersam.htm | Mirror Sites: http://www.repairfaq.org/REPAIR/F_mirror.html Important: Anything sent to the email address in the message header above is ignored unless my full name AND either lasers or electronics is included in the subject line.

That's the point of Freecycle -- get some more use out of it before it hits the dump. I have three Tandy 6000s and a whole bunch of hard drives in my garage - I'll try to redistribute them to collectors. If the OP has the skills by all means fix it. I just bought a new toaster -- for $8 -- but I plan to open my old one and see what's failed in it. Still, there simply are no parts for these any more. |
