How do I open the case of a Philips 107S 17" CRT Monitor?
Power switch is broken and I need to get the case apart to replace it. Case is at the held together by two screws at the bottom and appears to have internal fixing at the top. Most monitors have four screws with two on the sides near the top hidden behind snap off covers

There should be several philips screws on the back panel. (WARNING: Because you are opening a CRT, there is a extremely high voltage coil on the back of the CRT in the center. DO NOT TOUCH THIS WITH ANYTHING as it is DANGEROUS if you do.) With the exception of possibly a power supply fuze which you should be able to see next to the power transformer (where the power cord comes into the CRT case), there ARE NO USER-SERVICEABLE PARTS INSIDE. I recommend you buy a cheap LCD screen to replace it and dispose of the CRT through a recycling program. I hope this helps you.
The cord should pull right out, if not the monitor may have internal damage. If that is the case take it to an authorized repair shop. It may be under a recall or warranty. If you take the case apart it voids any and all warranties.
Get a long philips screw driver and remove the base and all fixing screws. some are hidden behind blanking plates and the com off with a sharp knife and a getle lifting at the join.
After all screws are removed the lie the screen downwards and start to pull away the backing.
you should get the case apart easily.
You must be aware of the tube holding a full charge at its end. DO NOT touch this at any point. The only thing you should try to inspect is the fuse or adjustment to the focus slant contrast etc. AndystUK
This monitor is trying to start but can't. The sound you're hereing is the B+ supply coming on and trying to start the high voltage system. Something down line, either the high voltage transformer or the Horizontal output circuit is faulty. I have repaired thousands of these. Generaly at $100. to $150. depending on parts. You can spend it to my company for repair or take to a local serviceman. If you decide to junk it and but a LCD monitor I would have to agree.
The Capacitors on the power board are usually the reason for failure of an LCD. If you open the HP VS17 ( I can provide an exhaustive step by step If I have to) remove the five screws for the power board ( larger of the two boards) and look for an area where there are 4 caps (see pic). Look for exploded, popped up, bulging, or leaking caps and replace with the same or slightly higher tolerances. The one I replaced last night were (2x )1000uf25-50volt and (2x) 470uf25-50volt. Check the rest of the board for similar issues and replace as needed.
