Had this exact problem diagnosed by a local repair shop as a bad LCD panel. According to the technician there's a loose ribbon cable on the panel and it would cost as much to replace/repair as a new TV.

Got to Samsung's support site and fill out a request:
http://www.samsung.com/us/support/service/request

You will be contacted by your regional repair center. I'm located in Milwaukee, WI and was contacted by a repair center in Elgin, IL, which is 60 miles away.

The regional center said they think it probably is a electrolytic capacitor issues, as multiple models of Samsung LCD's have this issue. They have defective (too low voltage) capacitors which will eventually give out. Unfortunately he said my model was not on the list they have for a free fix. He gave me the number to Samsung's Executive Customer Relations department, which I then called immediately. The woman there checked and found that my model indeed was covered - she updated the Support Request, and instructed me to call back the regional repair center.

I called back the regional repair center (immediately after finsihing with the ECR) and got a different person on the phone, and gave them my ticket number from my original request. He said since ECR updated it stating my model was covered they would fix it for free. If it's not the capacitors that are causing the problem I will be charged a 150$ fee, plus any parts required to fix the TV. I agreed to that since my local TV repair quoted me 200$ to fix the capacitor issue alone.

Today is January 25th, they have me scheduled to have a repair tech come to my place January 7th to do the repair.

You can fix the capacitors yourself for very cheap, maybe 20-30 bucks if you don't have anything: soldering gun/solder/flux/capacitors/etc...

I'd just go through the service request path, get it fixed for free and have a professional do it. Total time for me was 2 minutes for the service request, 10 minutes on phone for regional repair center, 10 minutes for ECR, 5 minutes for regional again. The repair is expected to take 15 minutes - most likely they'll just swap out the entire power supply board rather than the individual capacitors. Basically 1 hour of time to save minimally 150-250 dollars. I bet not many people asking to fix this make 150 bucks an hour...pretty simple math I think.

Screen is dim when power not plugged in


In power settings you will find the dim adjust, Your laptop has power settings you can adjust to your preference. That said, the default settings are usually set to a power saving that means when you unplug your laptop from th AC source your laptop will dim to the power savings settings and prolong battery life. Look in power settings by right clicking the power icon in the taskbar notification area and open the power options. There are many options to choose from I use High Preformance, but on battery it shorten battery life. If you need assistance just respond to this solution.

SAMSUNG 52 IN.LCD TV, WILL NOT COME ON, THE POWER & LIGHT BUTTON CLICKS ON & OFF CONSTANTLY


Sounds like it may have taken a surge. Did you unplug the set? Try that and give it 5 minute time out before powering back up.

Did anything happen before the problem started like a power outage? big storm? Brown out condition (that's when power is low due to excessive AC use in the summer and the lights grow dim etc - very bad for electronics and motors too)

Do a little more detective work and post your suspicions and findings.

Worse case scenario is there is something wrong inside your set and may need a visit to the repair center. How old is it?


Hope this helps.

Laptop ACER Aspire 4920 Screen goes dim.


there is a configuration of each one of the three plans of energy, and there you can change the time the screen is on when plugged or unplugged, the brightnes, and some stuff more like the wireless. you have to go to "energy option", or something like that... mine is in spanish. and then under each option is the configuration. good luck!!

The bottom of the screen has become darker!


Hi
The symptom you are telling is similar to FL inverter problem but with that case usually entire screen goes dim. You may try to reset the settings (Usually AUTO button). Unplug and plug in the electrical connection+Computer connection. Also make sure your Display setting in computer side has not been modified. If issue persist take to the qualified service center. FL inverter is the illuminator part of LCD works like fluorescent tube. FL inverter issue rather lower cost compare to other LCD issues.
Good Luck Happy New Year
