Question about Dell E173FP 17" LCD Flat Panel Monitor

1 Answer

Dell LCD TV powers on and after a few minutes shuts off by itself

I have a 2306C dell lcd tv, it has been turning itself off several times while i was watching it. I was told that it was a transistor, that makes the unit think it is hot and shuts it off. I was also told that it was not in the power supply. If anyone knows which transistor is causing the tv to turn off, i could repair it myself. I need location number so that i can find the part that is bad and the part number. any help will be greatly appreciated.

Thank you,

Mr. Lorenzo

Ok, this is the way how to examine where the problem is. You have to check that you can see the image on the screen by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see something moving, there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken. If you cannot see. I would say that there are some problems with the inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or dark spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.

Dell ST2210 suddenly will not power on. Tried different power cord, outlet, unplugging everything but the power cord and still nothing.

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

I have a Dell E197fpb LCD Monitor With Display Shutdown Problem. I have replaced the capacitors wit no luck. When I turn on the monitor it stays on for several seconds and displays fine. Then it shuts...

You may have bad lamps assembly problem, I use a set of test lamp to verify what I am working on to find out if it is the lamp problem or the inverter/power supply problem.
How are the voltages when the backlights stop working?

Monitor image flashes off and on

Sounds like you've done all the trouble shooting. If you just need that extra nudge, I would agree... it sounds like you'll be needing to shop for a new monitor.
