Question about Liquid Video L17LCD2 17" Flat Panel LCD Monitor
Monitor had been working perfectly until a couple of days ago. Now keeps cycling on and off. Briefly shows Envision splash screen, then briefly shows computer output display, then goes black, repeats...
I have checked the system with a known good monitor. The system is working properly. I have tested the monitor with known good cables.
I fear that there is a loose connection/failed solder joint, etc. inside the monitor. Cost to troubleshoot and repair would probably exceed replacement cost.
I am awaiting reply from Envision, but monitor is long out of warranty and I do not hold out much hope.
Davagain, Your stated symptom leads me to believe that L17LCD2 has a problem in it's power supply/electronic CCFT ballast circuit. The primary cause of the on/off, on/off, being that the SMPS is detecting a fault and then going into SHUTDOWN, trying to save it's self from catastrophic failure. This "failure mode" is typical of all brands across the board, not just Envision! And as the age and total number of hours of use grows, the "body count" also increases. I have, with luck, repaired a couple of them that were not of the catastrophic type. So, my advice to you is this. If Envision can't provide a viable solution, then work with a dealer to trade it in for NEW. If COST of new is still an issue, there are other options that may be of intrest to you. With a statement like "known good monitor" and "failed solder joint" I know you are NOT the typical consumer/user type of person. FYI also try search for "failed electrolytic capacitors" and or "swollen capacitors" and "bad caps", which also could be a culprit inside your Envision. In any case I would like to hear back from you on what your plan of action is. I will try to be of some help. Bye for now. lmistyrel@aim
