Common Electronics problems (1)
Sometimes our electronics appliances like TV monitor, radio or any other stuff may have a very simple problem. If we are not aware of this then we go in circles looking for the problem.<br />Technicians sometimes refer to this as intermittent problem. Sometimes the system will work and sometimes it will not. A tap/knock may get it working or will stop it from working.<br />Dry-solder joint is one of the causes.<br />If you are a novice and have no idea about electronics and how to work with soldering irons and electricity; please get assistance from a professional.<br />1. Switch off power.<br />2. Open the system up.<br />3. Discharge components which might hold charge to avoid electric shock.<br />4. Look at the bottom of the printed circuit board (track side of the PCB). You might need a hand lens for a closer look.<br />5. Look for cracks in the soldered components. Sometimes shaking components easily helps in identifying these cracks.<br />6. Once you get to know this, get your soldering iron, remove the old solder and re-solder the component.<br />7. You might be agitated to switch on and check your system at this point in time. Don't!!<br />8. Try and look for all the dry solder joints.<br />9. Fix as much dry solder joints as you can find.<br />10. Clean your board. Use isopropyl or general purpose thinner.<br />11. Double check the track side. There should not be any shorts that you may accidently done while soldering.<br />12. Once you are sure all is safe, assemble the system.<br />13. Connect a <span>series lamp</span> to the system and switch on to check.<br />14. If the problem stops; good for you. If it persists then continue looking for and treating dry solder joints.<br /><br />I will share more on series lamps in my next tip.<br /><br />Enjoy<br />Rjn<br /><br />

Gemstar 15" monitor/GM 171-B powers up but nothing on screen
You may have either the DC filter caps problem or the back light inverter board has failed, worst case will be bad lamps assembly. So check for 12vdc on the inverter board, bad caps with leaking/bulging top, bad solder joints.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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 monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

My mpc laptop cant openn programs like facebook and yahoo
some countries block these sites. Try going via a free web proxy (google for one) and see if this makes any difference although i would not been too keen to put your username and passwords in while using a free proxy as they may not be secure. The issue you have could also be with your security levels being set a little too high on your browser. You could try donwloading an alternative browser like Opera, Chrome, Firefox etc...
