Guest Capt K Ripendran Posted July 8, 2007 Posted July 8, 2007 I have a HP Pavilion 6511 preloaded with Windows 98 SE. The 14" Monitor is a HP Pavilion M50 CRT model No D5258A. I am unable to adjust using the front buttons as they are all JAMMED. Is there anyway, I could have them FREED? Thanking you Capt K Ripendran

It will cost you 10 or 15 bucks but will last a long time and has endless uses. An adjustable-force spray nozzle is nice. Put the straw into the nozzle and spray the hell out of the buttons - with the monitor unplugged. Put a paper towel over what you are doing or it will get all over everything (even with nozzle set to "low") - although it dries with "no residue", still... Push the buttons fast and as many times as you can immediately after spraying. Don't be afraid to press hard. Repeat if necessary. It will work better if you can manage to take the cover off the monitor and get at the buttons "from behind". But that's a little tricky and potentially dangerous - you might as well have a repair shop do the whole job. Shouldn't cost much. If the buttons won't budge no matter what, you WILL have to get the thing open (see above warning) and see what the problem is - it IS possible to replace the switches, you can get almost any switch (the button is just a piece of plastic in front of the switch itself) very cheaply from places like http://www.mouser.com (but then you have to solder them in place). If you don't care about the smell etc, WD-40 would probably work equally well. Some people claim it corrodes or melts certain materials, but I have used it for over 30 years with excellent results every time. -- Any mental activity is easy if it need not be subjected to reality.

All I can say is that my personal experience is the exact opposite of yours. If you read through some of the discussions (and flame wars) at sci.electronics.repair, you will find that, although a few people swear by WD40, most people, including its manufacturer, do not recommend using it for anything other than its stated purpose. Here are a few threads on the subject. Fixing flaky buttons: http://tinyurl.com/34pqwx Safe to use WD40 as switch or potentiometer cleaner? http://tinyurl.com/2khrqu And this is my own experience: WD40 - how to clean up the mess? http://tinyurl.com/39dws5 I'm not surprised that Wikipedia dedicates an entire article to this product: http://en.wikipedia.org/wiki/Wd40 - Franc Zabkar -- Please remove one 'i' from my address when replying by email.

Are you saying that rubbing it on your forearms to reduce arthritic pain (which I read about in the National Enquirer many years ago) DOES NOT WORK????!!!! I know, it's one of those endless subjects. I should have probably not mentioned the product in the first place.

But it didn't sound like the OP should be opening the monitor. WWOTS, I wonder WHAT the hell happened to make the buttons totally stuck? If they were (old-style) keyboard keys, then a spilled milkshake or something could be responsible, but buttons on a vertical surface? Of course, help groups and eternal gratitude Usenet-style being what they are, we'll never know. BTW, I once spilled a whole just-opened can of Coke (WITH sugar and caffeine) onto/into an electronically-controlled (AOT mechanical which many other brands were) Moviola 16mm flatbed editing machine. Nothing happened. I cleaned it up of course, but there were NO ill effects. Good thing, I certainly was not about to open THAT thing up. Also, just read the contents of your links and found them very entertaining and slightly informative (I didn't know about it dissolving capacitors, but have read before that it may disintegrate certain very rare plastics or plastic-like materials). Then again I would never advise anyone to spray it onto a circuit board, let alone liberally into the VCR tape cavity (I could not BELIEVE that part!) We were just talking about simple switches, and it was an alternate suggestion. [And I usually (foolish, I know) assume that most people are not complete idiots. (2 days ago a guy in a supermarket pointed to plain white milk and chocolate- and strawberry-flavored milk right next to it and asked me if I knew what the difference was... And he was NOT interested in what artificial coloring was used... He just apparently didn't know the difference between white and chocolate or strawberry.)] Still, BION, I *HAVE* sprayed WD-40 (very carefully, of course) into a few volume controls with excellent and years-lasting results. Of course, when I DO have a choice between something like Miller-Stephenson and WD-40, I use the former. And the best thing for cleaning gunk was always Freon. (In spite of what everyone is told, still happily manufactured in the USA and exported to and sold over the counter (as refrigerant, not cleaning spray) all over the third world - or at least the part of it I am familiar with.) -- Any mental activity is easy if it need not be subjected to a WD- 40 bath.

Otherwise you will need to explain yourself a bit better. By "all jammed", if you mean mechanically jammed, ie no tactile response, then I would suspect that some fixture has come adrift inside the monitor. If you mean electrically jammed, then I suspect that one button is stuck on and is hanging up the microprocessor that scans the switch matrix. Here are some photos of a pushbutton actuator assembly out of an old TV: http://www.users.on.net/~fzabkar/PushButton/ Each lever bears against a miniature button switch on a PCB. Sometimes the plastic levers break. They can sometimes be repaired by cutting a straight section of wire from the end of a spring and soldering it across the break. Your monitor may or may not have a similar arrangement. - Franc Zabkar -- Please remove one 'i' from my address when replying by email.
Guest Capt K Ripendran Posted August 1, 2007 Posted August 1, 2007 Re: Monitor Thank you ALL for the input. Regret my belated response! That is a good question Franc Zabkar. It seems to be "electrically jammed, with one button being stuck and hanging up the microprocessor that scans the switch matrix". Glen Ventura has given a picture of the monitor in his post. All I can say is that nothing has been spilt on the vertical surface. I had cleaned the inside of the monitor with a blower! Perhaps, some dust may have clogged the button/s?! In the absence of a "contact cleaner", can I try Thanatoid's soap & warm water method? Are the inside of the buttons accessible for such a cleaning?

If so, then I'd lay the monitor down on its face on a towel or soft cloth, remove the back, and use my common sense. Either the plastic button is physically jammed, or the switch behind it is permanently closed. Check the switch for "clickiness" or measure its resistance with a multimeter. BTW, I'm assuming that you're not talking about the on/off switch. - Franc Zabkar -- Please remove one 'i' from my address when replying by email.
