Sound only, no picture.

Most likely, the CCFL (cold cathode flourescent lamp) bulbs are bad or they are not getting power.

Your picture is probably there, but because the backlighting is out, you cannot see it.

If you still have a warranty, exchange the set. Otherwise, you can go to any good TV repair shop and they can fix it for you. Make sure you get an estimate first.

I have problems with colors on my SONY SDM S73 LCD. Many of lighter colors are not displayed at all. I tried to update a driver, chanfe resolution, nothing changed... I use WinXP SP3 with RAGE 128 PRO...

tlnwiayqydee, In terms of lcd monitor age, unit is VERY OLD. Cold cathode fluorescent lamps will need to be changed for new ones. Very hard to do for consumer/user!!! Best if you trade-in for new unit. Did you even look at the "date of manufacture" on back of unit? Look here for lamp information: and and and You will need to also visit YOUTUBE for video clips of units being repaired. 12fixlouie

Hi,WHEN I power up my screen it flashes on momentarily then goes off and no power light indicator! any ideas. Black screen.

h_ba_adams, Sorry, Retrevo .com lists this unit as "time to retire".. Your unit suffers from a bad power supply that goes into "shutdown mode" when it detects a problem with itself or another circuit! Remember this! Your "cold-cathode-fluorescent-lamp", back-lit lcd display isn't any different than any other brand in it's design and basic mode of operation!! View some lcd monitor repair videos at YOUTUBE. Then you can make decision if you will repair (DIY) or trade-in for new unit. Do reply if this was helpful and give this a rating on fixya.

Display flickers, no image is displayed, buzzes at same time it flickers. tried it on multiple computers, same thing

jglendenning, If not into soldering irons, solder, meters, and electronic repair of "switch-mode-power-supplys/cold-cathode-fluorescent-lamp ballast-circuits" then trade for new unit! Retrevo .com lists K717s as time to retire unit. Before you do anything check out the longer and more useful video clips at YOUTUBE that deal with "lcd monitor disassembly" and "lcd monitor repair" FYI so you at least know what is inside a typical desktop CCFL back-lit LCD monitor. 99% use same basic design and principle of operation no matter what brand of unit you have or will purchase in future!!! Hope this helped some. 12fixlouie

At infrequent times , the monitor L17PS Goes pinkish and there is a flickering of horizontal lines

victor_adams, If reconnecting the VGA cable to the pc several times won't cure problem, may need to fix or refurbish the units switch-mode-power-supply and or replace the cold-cathode-fluorescent-lamps with new ones! Not an easy task for newbie!!! Retrevo. com says its time to retire this unit and get new one. Visit YOUTUBE for video clips of lcd monitor disassembly and lcd monitor repair before you jump into trying to repair/refurbish this old unit!!! 12fixlouie

Back light goes out after about 15 minutes.

ayonbaxter, You will need to determine if unit has one or more of these things as the cause of your BACKLIGHT FAILURE. 1. Bad solder joint on printed circuit board. 2. Swollen, leaky electrolytic filter capacitors on switch-mode-power-supply/inverter circuit board. You will need to search youtube for video clips that deal with just that type of failure mode to understand things like "bad caps" "frosty" "cold" solder joints and how to effect a possible repair to your unit. Learn all you can about poor soldering and THERMALLY INTERMITTANT solder connections of passive & active (solid state devices) components on the power supply boards that power your LCD backlights (cold-cathode-fluorescent-lamps) CCFLs!!! Tons of info all over the web!!! Then you will know what ails your LCD monitor. Hope this helps you. 12fixlouie

My backlight in my laptophas stopped working

Assuming the laptop has not gone into a hibernate mode and is operating, it is possible the invertor that drive the cold-cathode flourescent lamps may have failed. This hapens at times. Replacement of the part is only solution. The lamps themselves seldom fail unless they have been broken by crushing the unit.

there should be a button on the display to bring up the options or menu which you need to look for brightness/contrast if these are both at setting 100 your backlighting CCFL tubes (cold cathode flourescent) like flourescent bulbs in the ceiling are burning out slowly they can be replaced but it is not a common repair for a local computer store you may neeed to find a specialist.

Dark Screen

almost all LCD use a flourescent lamp, some very new and expensive types use OLED.
