    dadymck, First, look at the date of manufacture on rear of E171FP! It's "OLDER THAN DIRT" in terms of monitor age!!! Retrevo .com lists unit as time to retire! If you want to fix the power supply/ CCFL inverter circuit and install new CCFL lamps then visit YOUTUBE for video clips of owners/technicians that show you how to do it! After you view clips you will make decision to DIY fix or just trade for new wide screen unit. let us tech's know what your decision is by doing additional comment after you do YOUTUBE research!!! 12ixlouie

If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), 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 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.

I have a JVC LED TV (LT-42X579). The screen goes black intermittently and then comes back after a few seconds. This happens with my PS3 (component) and antenna feed (COAX). Any sugestions?


Hello, do you keep the sound? if you do, take a flashlight when it goes out and shine it across the screen, can you see a dim image? if you do the L.E.D. driver/power supply board may be bad. let me know....tks

Why does screen go black after a few seconds


Hope this helps.... Your monitor has an inverter issue. You know it's an inverter problem when:
1. Your monitor starts normally and displays the startup/desktop screen for a while.
2. Then it suddenly goes off, leaving a blank (black) screen or a very dim display.

To fix this black screen problem, change the inverter board (based on your monitor brand).

Screen doesn't want to come on, then goes dim


The problem is caused by one of the inverter transformers, or one of the backlights behind the LCD screen is going.

Screen comes on but dims after a second. The light goes off. Can still see info on screen but very dim.


The problem is probably a back light fault, this is caused by a faulty inverter or a faulty CCFL lamp.

That's better.
Yep, 95% chance it is the power inverter problem.
If you don't remember the screen having a pink tint or flickering for a while or being dark at the middle top or bottom before it went, then your bulbs should be okay.
It will need at least all the capacitors replaced.
I fix many of these types on ebay.

LCD goes dim within 1-2 minutes


You could have a bad "inverter" or flourescent backlight tube, or a problem in your power supply.The only way to isolate the problem is to check each component in sequence.If your hard disk and DVD / CD drive are still working when your screen goes dark, then I'd say it's the "inverter". You'll have to take it to a repair shop.
