My compact W185q monitor was dead due to shorted circuit caused by cockroach. i saw 2 PCBs inside but don't know which one is bad.can it be repaired or where can i buy a new PCB?many thanks..

If your Milwaukee 6390 circular saw is tripping the circuit breaker even without an extension cord, it could be due to a few reasons:

1. Overloaded circuit: The circuit may be overloaded with too many other electrical devices or appliances. Try unplugging other devices or turning off lights on the same circuit to see if that resolves the issue.
2. Short circuit: A short circuit can occur when the insulation on the electrical wires inside the saw becomes damaged or frayed, causing them to come into contact with each other. This can cause a sudden increase in current flow, which can trip the circuit breaker. Check the saw's power cord for any visible damage or wear, and consider having it professionally inspected if you suspect a short circuit.
3. Faulty circuit breaker: It's possible that the circuit breaker itself is faulty or worn out. Try plugging the saw into a different circuit and see if it still trips the breaker. If it does, the issue may be with the saw itself.
4. Motor overload: If the saw's motor is under strain or is overloaded, it can trip the circuit breaker. Check the blade for any binding or resistance, and ensure that the blade is sharp and properly aligned.

If none of these solutions resolve the issue, you may want to consider taking the saw to a professional repair shop to have it inspected and repaired.

More likely to have power supply failure due to bad DC filter caps.

If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed HP monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/

Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague

Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you.

Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.
Please leave rating if it helps.

It is blinking can be due to not getting the video signal or it is in safety shutdown mode due to short circuits or failed power supply due to bad caps or shorted out some where inside. Try it with another PC first.

Try it on another PC first, if it still does not work then you will have to open it up. If you are going to DIY repair, then please read below and look at my albums so you will know what to look for inside.

It can be that it is not getting the signal from the PC, or it detects short circuits so it goes into shutdown and try to restart, or failed power supply due to bad caps. Try it on another PC and also check the VGA cable first. If it still does not work and you want to DIY repair, then please read below and look at alot of pictures so you will know what to look for inside.

It can be that the power supply failed due to bad caps, failed inverter circuits due to shorted transistors or transformers, failed lamp assmblies due to burnt wires or just bad lamps.
Please look through my pictures so you will know what to look for inside if you are going to DIY repair.

Not likely to be sleeping but the failure in the power supply due to bad caps (bulging, leaking), very common in ALL LCD monitors. If you are going to DIY repair, please read below and look through my albums so you will know what to look for inside.

Sounds like overheating of something inside. Open the monitor, get access to PCBs and observe for darkened areas especially over the power supply and inverter. Also that long working before shut down may tell about bad solder junction, also caused by constant local overheating - look for those with tiny cracks, especially over darkened areas on PCBs.
Most likely - that's the source of problem with your monitor. And, as far as you open the monitor, check for any popped electrolytic capacitor - never bad to replace them too.
