Having problems with your Relisys RLT1720 17" LCD Monitor ?

Monitor displays breifly then goes to blank screen

\015 Hi, Whenever I turn on my monitor it displays the computers output briefly (~half a second) before going blank. I have tried the monitor on two other computers with the same result so it is definetaly not a computer problem. The power light on the front of the monitor stays green when the screen goes blank. Whenever I turn the power off and back on again the exact same thing happens.\015\012Help please!!\015

Well my Acer AL1711 finally gave up in as much as the screen flashed briefly at switch-on then went blank, regardless of brilliance setting so I decided to take it apart and try to fix it. The good news is that IT WAS NOT THE LAMPS that I feared in my earlier post and was easier than I had ever dreamed! First allow a good period of time for the internal components to discharge before starting. Remove the plastic clip at the base hinge to expose 4 screws - remove all four to release the stand. Then remove the 4 black cross head screws that appear to hold the back on, they do but there is more to do. Carefully tease the silver surround away from the case, best to start in the centre of each side and finish at the corners. There are many plastic clips to release before the surround comes away. Now remove the four cross head screws holding the pushbutton switch circuit board. The whole assembly can now be removed from the case and reveal a metal cover held by 2 SHORT (remember that!) SHORT! threaded machine screws. These once removed will allow the case to be slid away from the holding tabs located down the edges of the cover and removed. Now unplug the connectors from the board that has the mains input connector attached to it. You will see a heatsink with 4 electrolytic caps above it. Silly ACER designers, have placed the capacitors so that they get all the heat from the heatsink! Yes folks, the capacitors are above the heatsink when the monitor is in its normal operating position! So all the convected heat dries them out, nice. So the fault is due to a silly design error!\015\012Replace all 4 capacitors, two of them are 1000uF at 16V and the other two are 470uF at 16V, all radial types. Try and get capacitors with the highest operating temperature, at least 105 degree types and remember these are polarised, make sure you connect the capacitor + wire to + on the circuit board. You should have no problems with re-assembly but don't put the wrong screw where the short ones went or you are liable to see it come out of the screen LOL! Most important - - Don't forget the screw holding the earth tag to chassis. Good Luck, you will be amazed how much brighter the screen is now!
Hi scuball,\015\012\015\012\015\012**PLEASE NOTE - This solution applies to ALL LCD's but NOT CRT's**\015\012\015\012\015\012It's a very common problem with all LCD monitors\015\012\015\012LCD's use four small Cold Compact Fluorescent bulbs to back light the display. (thats what gives the LCD it's brightness allowing you to see it)\015\012\015\012The inverter board runs these lights and when they go bad they will typically show symptoms like you have or the monitor power light comes on and you have either no display or a very dim display.\015\012\015\012If you ever have one that has no display but the power light is on you can check by shining a flashlight directly into the LCD from the front (right into the screen) if you can see an image then it's either the inverter board (most likely) or the CCFL bulbs have gone bad.\015\012\015\012The inverter board and CCFL's are replaceable.\015\012\015\012Good Luck,\015\012El Duderino\015\012\015\012\015\012**PLEASE NOTE - This solution applies to ALL LCD's but NOT CRT's**
