I have inherited a VG150 and it has a dead power switch. How do I open the case to replace the switch? I plan to install a cheap switch from Radio Shack doing a bit of soldering and gluing something over the hole where the original switch was.
I undid all the screws but can't get the case apart. I don't want to risk breaking it. How do I open the case?
There are tabs along the sides so you need to remove all screws and then use something like a screwdriver to pry it open... careful not to scuff the plastic. Anyhow the switch is probably fine and your main board is dead. There are several posts on the web about this issue, and mine had the same problem. Once I replaced the main board I found on ebay, it worked just fine.

hi...if your friend say so it not valve rather a fuse bulb!!!! you can find it inside the casing.. try to unscrew the top casing...if you see the power supply section (mostly w/ many capacitors and power switching transistors).. if you can find the glass like tube...if there's a light discoloration..replace it w/ same type.... also check the power cord if there's a cut or open wire.... hope this help..good day please rate and vote....
E000 Indicates either of the following: the main thermistor (TH1) has poor contact or an open circuit; the thermal switch (TP1) has an open circuit; the main/sub heater has an open circuit; the main power supply PCB is faulty; the DC controller PCB is fatly; the door switch is faulty.
In the case of E000 through E003, the code will not be reset when the main power switch is turned off, requiring the use of service mode (COPIER>FUNCTION>CLEAR>ERROR). However, if E001 or E003 is detected within 3 sec after the front door switch is identified to have been opened or closed, the code will be reset when the main power switch is turned off and then on. This consideration is to prevent a service call in response to an error detected when the switch operation is not fully stable (as immediately after turning off and then on the main power switch).
greg_olive, Possible failure of "cold-cathode-fluorescent-lamp" power supply called INVERTER CIRCUIT inside of monitor. If "lay on floor" black brick "switch-mode-power-supply" detects fault with CCFL inverter it will go into full or partial "shutdown" mode to try and save itself from having a catastrophic, nonrecoverable failure. e.g. sparks, smoke. fire. A tech will need to investigate it. Your monitor no different than any other CCFL backlit LCD brand in it's basic operating principle!!! Read more of my and other techs FIXYA profiles for more info and options that are open to you as a consumer/user of lcd monitors. Black, or black and blank is you're and thousand's of other users symptom. If pocket is deep enough, take the easy way out! Trade for new! If not, then you will have a lot of reading and surfing to do. Two other very good tech types on fixya have nicknames "budmrtn" and "buddymc" !! Read their stuff also for more info. good luck with repair. 12fixlouie north of Windy City
If you can open and removed the power supply/inverter board you can check the caps for obvious damage. *(leakage or swelling)
You can pull the offending cap or just do what I did and replace ALL the caps on that part of the power circuit. It isn't expensive and the board is big enough to handle soldering without a lot of hassles.
I did this for an old Dell monitor this past week and it is up and running!
Nice and bright too.
Your question fails to provide sufficient information.
.."doesn;t turn on power good...." do any lights on the pc illuminate was it working before, and did it close down correctly has it possibly been hit by lightning have you recently opened the case to install new hardware?
Possible causes of a failed power up. dead power supply a video card not seated in its slot correctly dud motherboard motherboard installed incorrectly no Bios battery on motherboard faulty wall switch faulty power pack switch no ram installed
The power supply in most computers has a fuse, either internal or external, that can blow without you noticing. Basically, you've been on battery operation this whole time, and the battery's finally gone dead. It will be necessary to open the case and examine the power supply section. It may be possible to replace the fuse yourself, but any operation of this nature that involves opening the case will void any warranty you may have.
