Digital power consumption monitoring

Good day. I am jay-r, an electrical engineering student. We really are having problems in making circuit diagram for our project. It is appliance digital power consumption monitoring. That could display power, energy, power factor and VA. We already had made a circuit if it, but were not yet really sure... we are too having problem in converting analog to digital ... we would really be grateful if you could help us.

Power saving mode


Power saving modes are automatic for some LCD monitors some have setting like after 20 ,30 mins to an hour the computer monitor itself will go into standy saving modes like power led switch indication go to yellow led lighting or the monitor of the lcd screen go blank if ur computer have no pictures for displaying as a screen saver modes.Power saving modes it best for uses if ur computer it on all day long.If u don't touch the mouse or a keyboard the monitor will go in the power saving modes for less electricities consumption for less stress for the monitor electronic components for working to hard for the monitor not to malfuctions sooner or the monitor life cut too short because the computer it on all day.

BenQ Q24W5 LCD monitor circuit diagram


HI.............


Repairing BenQ 17′ LCD Monitor

benqlcd.jpg
I came across a common fault problem in BenQ 17′ LCD Monitor. The problem is have power but no display. Once you has opened the LCD cover, check the pico fuse for open circuit (very common), the push pull transistors C5707 for short circuit and the Buck royer circuit p-channel fet FQU11P06 also for short circuit too. For your information, if you can't get the FQU11p06 you can always use FU9024N as a replacement. Resolder all the high voltage transformer pins and replace the components above and I'm sure you will bring back the life of this BenQ 17′ LCD Monitor.
You may go to this fairchild semiconductor website to download the spec of the FQU11P06 P-channel FET.

Tick tick sound appear from acer 15" crt monitor power supply circuit


the sound you heard come from power regulator. its just fine, just indicate that part are over heat.
maybe you ill consider replace your monitor with LCD. more friendly for your eye and less power consumption

Cornea 1810 monitor power cord


Apparently the monitor's power consumption is near or slightly exceeds the specified value.
My suggestion would be to purchase an adapter with higher rated output current - if for example your original adapter was rated 12V 4.5A, go for a 12V 6A rated adapter. A 30% safety overhead will hopefully contribute to higher reliability.

Samsung monitor picture clicks off after 2-5 seconds...


Yes, It sounds like the backlight inverter circuit is shutting down. No inverter power, no backlight. On some monitors the inverter circuit will shot circuit the power power supply which makes the power light flash on some it just kills the backlight. You can usually check with a flashlight. Hold the flashlight pointed at the screen and see if you can see any of the icons or background picture. If you can then it is the backlight circuit or backlight tubes, usually the circuit.

Screen stays white but works after awile then i turn off it gos b


if this is a CRT monitor the problem is your flyback. It is located at the rear part of the monitor (inside) and it very dangerous to touch. It has a several thousand of stored power on it and may cause death if you don't know how to handle it.

Advice: for practicality, LCD monitors now a days are much cheaper than before. several advantage of this are low electricity consumption, not painful to eyes (if long use), save up more space and sharp and clear screen.

Monitor problem


Hi,

Appreciate the "Ask Me".

I am assuming that you have more than just familiarity with electronic components and circuitry, the use of a DVM and a soldering iron. Further, that you have access to a service manual.

Width problem is basically insufficient horizontal deflection, then analysis would have to be in the horizontal section. Areas to initially focus on:
  1. 12V line and pin 29 of IC401;
  2. 110 V peak to peak at collector of Q403, if yes check Q 402 & 404 as well as T401;
  3. other components that affect the horizontal size are:
  • IC201
  • Q 405, 406, 407 & 408;
  • D409
  • L401
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Horizontal lines on Screen


Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!
