Re: power supply problem

You know first of all you must b sure of what electricty voltage iis supplied at your home.. well im from maurotius and here we are supplied about 230v,therefore it is recommended for ur to tune our power supply at 230v.. But sometimes there is a high frequency of voltage which passes through our cable and this may cause prob.. the best solution is to try to change your power supply..this might b the solution for your problem. dont worry as its not expensive.. if still you are getting problems,then try to serach for a pc technician,if you do not know anything about power supplys,then never try to play with it.. it may cause damage to other parts of your pc.. mail me at if you still have another problems.. take me as your friend..

Want schematic for viewsonic monitor va1930wm

Hi Marcel, thanks for using FixYa.

While I could not find the precise schematics you were looking for, here are some helpful tips you can use to find them before you go to a repairman to fix your TV.

Do you still have your original box and manual? Some companies include the schematics here or provide you a phone number to call to find them.
Utilize Viewsonic's support page found here.
Email for schematic information. You will likely have to purchase them however.
Some big stores like Best Buy are able to order the schematics from the manufacturer if the customer service representative is unable or unwilling to give you the correct information.

Unless you can find someone who has the schematics (either online or on here), it is likely that you will have to purchase them yourself.

Emailing is probably your best bet to find them.

Hope that helps!

Dell Flat Screen off/on switch broken

Mohons, Get with the the program, will ya!! A video clip is worth a thousand words!! Try a search at YOUTUBE for the longer 6 to 10 minute video clips of "LCD monitor disassembly" and "LCD monitor repair". Here is a clue. "Parting the rear cover from the front plastic bezel is the hardest part." Go watch some video. You will be glad you did. And while your inside the monitor, why don't you check the "switch-mode-power-supply board for any swollen and/or leaky electrolytic filter capacitors! Do you have an OHM-Meter or DVM to check the switch? Bye for now. 12fixlouie
ps. could be SMPS is not "listening" to a GOOD switch!

Monitor L17AMTN flashes WinXP desktop, then blanks.

dmellman, Before you open it up, try this! With fully booted pc and WIN DESKTOP screen up, reconnect the L17AMTN . Have a bright flashlight handy so that when the lcd screen flashes on for 1 second and then goes dark, you will want to check to see if the desktop remains on the screen even though you think it went away. Shine the light 1-2 inches from screen at different angles. Has the desk top completely disappeared or is it still being displayed? Do you know about Cold-Cathode-Fluorescent tubes and their Inverter type power supply? I assume that this unit also has a "lay on floor black box switch-mode-power-supply" that is supposed to supply raw 12v-14v dc to the monitor? This symptom is typical of lcd monitor power supply failure, and or inverter board failure. Not to mention the fact that the CCFT's could be a bit tired from use. YOUTUBE has some videos on taking apart lcd monitors. also do search on web for "bad caps on lcd boards" or "bad caps in lcd monitors". I should think that this Tatung might suffer from swollen cap-itis. get back to me with results of your investigation. Im louie12fix on fixya or just nrth of Windy City

Unidentifiable capacitor?

What i would suggest is taking those numbers going to your favorite search engine and entering them. Alot of times search engines can give data concerning hardware parts just by there manufacture number. This will give you a foundation to find what that particular part is and also maybe a replacement part. A word of caution about working with capacitors. Even after power has been off for several hours they can still hold a deadly charge. If you have a volt meter I would use it to test the part before even thinking about it. Capacitors are nothing to mess with unless you have proper knowlege on how to handle them and discharge them.
