1 Answer

My monitor is not turning on, when i push power button, no light.

My technician said it was the defective parts "its called TRANSISTOR" its place near the playback, with 3 pin.place with heatsink he said.
My problem is i dont remember the serial num or the number write on the chip, coz' i was lose the part he take up. i need only the serial or the code number write on the chip, so i can replace the defective parts.

Your technician is talking about the horizontal output transistor near the flyback transformer. These things get hot during operation so they are mounted on a heatsink. If you really want to try to repair the monitor, you can take the back off the monitor and read the part number right off the transistor. There are many sources for transistors, although not all parts are easy to find.

I wouldn't recommend trying this repair. First, it's not a simple matter of unplugging a part and putting in the new one. They are soldered in so you'll need some some experience with desoldering and resoldering. Also, while horizontal output transistors do sometimes just fail, they usually go bad because other parts fail first. If you don't have some experience with troubleshooting this kind of equipment, you may be wasting time and money trying to fix this yourself. There are also dangerous voltages present in the monitor, even after it's been off for a while, that can shock or even kill you.

So many people are replacing monitors today with flat screens that you should be able to find one for very little money or even free. If there are resale shops (Goodwill, etc.) in your area, that's a good source. I've seen monitors in shops around here for $10. There are also flea markets, ads in your local newspaper, Craigslist online. It would be safer and less costly to think about replacing your monitor.

My AOpen 19" LCD Flat Screen Monitor (Model F2915) is like new and works perfectly except for one thing. The push button power switch located on the top of the monitor has broken off and fallen insid


Certainly, if you jumper the connections to see which ones turn the monitor on or off, then you can go to an electrical supply place and get a micro switch and wire it in in place of the power button, or perhaps find a type that is flat that the power button can press. What you need to determine is if it is a push-on, push -off type switch, which always stays on or off depending on position or if it is a momentary interrupt switch where the button pressed momentarily turns it on and then releases and a second press connects the circuit to turn it off. You can do this by testing with your jumper wire, attach it and if the monitor stays on when you remove it, then goes off when you attach it again, you need the second type switch, if it goes off when removed, you need the always-on always -off first type switch. .

Turned off and on, Now no power, happen to ten monitors at once


Commonly there are 2 defective capacitors near the switching transistor located on the power supply PCB that fail causing a no power issue. After replacing these capacitors power on and check operation for any further issues.

You have shorted out transistors in the backlight inverter circuits.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, 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 DELL 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 monitor will not shut down - screen stays white


You got a short circuit in one transistor located at the inverter area. The transistor is acting like a conductor and not shutting down the power to the back light inverter. If you are a technician and want to fix it, look for short circuits in transistors.

Good luck.

Hello,

You have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of he monitor. If you are good at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictues and your monitor should work fine. The capacitors do need to be installed with the correct + and -connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. If your problem is not the capacitors then it would be the backlights and that is much more difficult to replace.

I hope this helps, if so please rate my solution.

Sharp LC-37SB24U will not turn on


From the information you have provided failed capacitors in the power supply is likely causing the problem. The safety circuitry shuts the TV set down when it detects a problem. This model of TV has over 2,000 parts which include millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Integrated circuits and transistors can go bad. This can cause other components to become defective, which can have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again since if the parts that caused the failure to begin with are not replaced. The only way to know for sure what is causing the problem, which parts that are no longer within factory specs and for proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment and the skills to use the test equipment. The repair should cost about $250 if carried into a TV repair shop. A small TV repair shop will often charge less than a large repair facility.
