SOURCE: blinking monitor power button and flashing image

I buy and sell these monitors (Dell E17FP) the problem is with the transisters (Q739, Q740, Q759, Q760) they short out and the monitor will just blink on and off. You have to desolder them and test them with a simple battery and light circuit. The reason they blow is because of the dirty solder joints by the transformers. If only on pair of backlights work the problem maybe transisters Q751, Q743. I home this answers your questions.

SOURCE: Dell E152FPc Monitor powers up, and screen goes blank in 5-10 sec

ok every one there is a fix the are 4 transistor 2sc5707 and 2 transistorfu9024n and i cap 16v1000uf
if you replace these your problem will be fix for a while but to it better then dell replace the 2sc57o07 with radio shack tip3055 they are 15 amp trans instead of the low 8 amp dell uses they fail because the amps at the test for the transistor is more than 8amps all the correct parts are sold in a kit on ebay look up the 2sc5707 but i recommend upgrading to the tip3055 transistors they are a bigger transistor but you can lay them down and they work great. the capicator can be found at radio 35v1000uf is a good replacment make you monitor better because the new parts are stronger then the originals so no more failures after.

SOURCE: Dell E173FPc monitor worked fine yesterday.

Hello,

The power supply in the unit has died. This is a very common problem with this series of monitor after 2-3 years of use. If you can solder then you should be able to do the repair yourself. Check out our step by step repair guide posted on our site at: www.ccl-la.com Our guide gives parts values and location information as well as how to open the unit up. If you don't feel like doing the repair we also offer repair services, see our web site for details.

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

Monitor intermittent power problems. Horizontal green flickering lines


You have to check the ESR in tha caps in power supply with esr meter.
If you dont have one just replace all capacitors in the power section(there are severals of them)This is the simptom of low esr in the capacitors.
Return the monitor in factory settings.

Isolate the problem per above. Eliminate the monitor, split cable and software settings so that each, individually work. Then eliminate team board - do you have a spare?
It could mean sharing the monitor signal means weakens it so that one can display and the other does not work. Prove it with a different source computer. Don't know if buffer devices exist or how to increase input sensitivity.

Laptop screen goes blank


If the monitor hookup solves the problem it means the inverter board located under the screen is intermittent, or the baclight behind the display may be the issue, and you may have a loose video cord from the screen to the motherboard plugin. But if both screens show the same symptom, it is the video graphics chip built into the motherboard.

Dell monitor screen suddenly went white. Can it be fixed?


I have a strong suspicion that you have burned a capacitor or two on the monitor. You will need to bring this in to have it serviced as it will require the monitor to be opened up and new capacitors replaced/resoldered.

When I turn my MacBook air on a blank White screen


Leave the Macbook air turned on until the battery goes dead. Then Connect to power and start it up. That should solve the problem. You problem was caused by not letting an update install in full.
