Faults & possible causes to LCD & Plasma screen are given with illustrations. You can get an idea about the fault to an extent. Faults to all LCD & Plasma screen are similar, irrespective of its brand and screen size.
This appears to be a faulty CCFL lamp which supplies the back-light.
Because it is less than 6 months old, I suggest you get it fixed under warranty.
If you try to fix it yourself you will void your warranty.
You're probably lucky that this happened now. You're most likely still covered under warranty. Contact Acer support and arrange a swap. If your pc works okay with another monitor there's no point in troubleshooting further. Get that monitor switched before the warranty runs out.
As long as the remaining warranty is still in place, that is normal procedure. You can request a new one or to have the existing one repaired, but in reality, repairing your set is equivalent to getting a refurbished one. The refurbished ones are just ones that have been repaired under warranty when returned to Sony from a store because of a warranty exchange. Normally warranty claims that occur less than 30 days from purchase are handled at the retailer without involving the manufacturer until the unit is returned by the retailer to the manufacturer.
The exchange for a refurbished unit is just a way to have your problem resolved in as little time as possible without effecting the warranty.
Hope this explanation helps. (I've been a warranty station for numerous companies,)
Well if you take a strong light like a flashlight and you can see a faint image. Then the lamp (CCFL) or the lamp's inverter has failed. It should work fine with an external monitor. Still not good though and usually expensive to repair (unless it is still under warranty).
Similar problem with an eleven and a half month old LT-40148. Approx. 1 inch vertical banding line on left side of screen on all inputs. After about two weeks, same problem on the right side of the screen.
Fortunately this occurred two weeks prior to the one year warranty expiring.
Called Mits customer service and they referred me to an authorized service center who I happened to have dealt with before.
They picked up the set. The front panel (LCD screen ) had to be replaced. Set was gone for two weeks as parts were not in stock. There was no charge. I hope this screen last more than a year.
Don't worry, water won't damage your screen permanently and will 'evaporate' in time, but for now you have to live with the effects it has on your screen. It will be more like a few months then days but it will heal in time
Since the TV is only 2 months pld, it must be covered under Warranty. Just take it to the Service Centre and get it fixed.
Froim your description it seems that the Horizontal Oscillator or Output section has a short circuit.
