I fixed my with 100% Silicone RTV adhesive, just put the button back in the hole and apply a blob of RTV to what you left of the broken button hinges, the button is being held in place by small molded palstic hinges, it is a very cheap way of making button assembly for expensive monitor, they skimped on this one.

Open the monitor, unscrew the dash buttons and then as budmrtn said above, glue the button onto the lame cheap plastic.

Hello My hpf2105 went blank and does not function... I would like to know what can be done...


There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Please post back what you find.

Philips 170S LCD - OSD locked and unable to remove display from screen, unable to adjust. Locked on Brightness setting which continually drops to 0. Any thoughts on how to fix?


It kind of sounds like one ore more of the buttons are stuck. Any chance something got spilt on them? Try pushing all the buttons repeatedly to see if any feel different or stuck.

Screen broke


Hi ,

It's normally the "Fn" key together with one of your "F" keys, eg. Fn+F2

Try and see if it works

Good Luck

Micro switch for on/off button broke how to fix and remove casing


Tonylpaul, Try mouser .com catalog pages 1282 thru 1291 You should find something that will work. Also visit YOUTUBE and search for lcd monitor disassembly videos to see how to get the thing apart. I'm louie12fix on fixya or lmistyrel@ aol.com Note: Is the switch Truly BAD? Did an elephant step on it? HMMMM ??? I wonder if this DELL has a power supply (internal) problem????

If the lines are running top to bottom and are perfectly straight then your panel is failing.
The only repair is to have it replaced. It can be sent off and have the driver tabs repaired, but the sheer cost of that operation is far more expensive then a new monitor.
The next best option is to look for another monitor on a certain online auction site with a failed power supply and salvage the panel from that.
Even buying just a panel (new) will be more expensive or as expensive as a replacment monitor.

Sorry, it's just the way technology moves.
If it has any warranty left, then return it under that warranty. Most LCD's have a 3 year warranty, so it is worth checking up on. Look for the "Date of manufacture" on the sticker on the back of the monitor.
