While tracing the circuit I discovered that all resistors measured 10K Ohm as they should have except for the one related to the Auto Adjust button – it was a little low at 9. The old capacitor array came off cleanly with the hot air and then I cleaned up the pads with the iron and solder wick. It’s black in colour. Add Your Answer Tips for a great answer: I tried it without a load, and got fluctuating voltages on both rails and ticking, but I didn’t much notice of that since a previously repaired LCD monitor PSU also power-cycled without a load.

Are you a Computer and Internet Expert? Mechanical Display Position Adjustments. I still need a better solution to dispensing the paste, but I managed to get by with tweezers and a bit of dicking around You can’t post conmments that contain an email address. Vmv, the PSU was looking like the problem.
Please assign your manual to a product: Thank you very much for that, PlainBill Now at least I know what I need to get – but it doesn’t look like it will be easy The Belinea monitor uses a separate capacitor for each button, whereas my Chimei cmb 2x 4-way capacitor arrays in a size package. Power Device Nominal Voltage. I was using it and it just shut off, and wouldn’t come back cnv again. Please enter a valid email address.
Flat Panel Mount Interface. However, now I have a hot air rework station plus a decent set of tips on a temperature-controlled soldering station and have had practice since then. Maybe someone can suggest a workaround to your cap problem. What you have described could be many different problems and without more information I cannot say which one it is. The 12v rail was there, but to my surprise, the 5v rail was bouncing up and down around 2.

Auto and – are same circuit, resistor makes them logic high or low. Last edited by Toasty; at Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US. The power supply could cause similar problems if it cannot supply enough power because the highest power draw is when you first turn on the computer.

Something probably firmware is causing your video card to not start up properly when power is first applied. After taking care to put a uniform cmb thin amount of paste on the pads you really need a lot less solder on these arrays than with bigger parts I brought the hot air in on slow speed, and reflowed the solder perfectly See the attached photo.
CHIMEI CMV T39D – LCD monitor – 20″
Firstly, I wasn’t convinced that the capacitor array I had ordered originally was correct, as I had never had a schematic. Speakers – stereo – integrated. When the power supply detects a short circuit, it turn off by itself.
Here’s a link to this great service Good luck! New Zealand Line Voltage: Find More Posts by Toasty. I think Farnell might be a better fit. Monitors by Rick Broida Sep 24, Here is a link to the complete specs. Originally Posted by ek2oo2.

When you try several times, you may be able to “bypass” the circuit protection but the damaged parts still having problems. At the time, there was also the problem of my bad SMT soldering skills and equipment or lack thereof.
Putting the capacitor there instead would fit the schematic, but isn’t the point of them being on the logic board that they’re close to the ICs? Great work by PlainBill for tt38d the schematic of cmmv obscur monitor with one from another obscur monitor!
