Question about Westinghouse L2046NV Monitor

1 Answer

LCD Monitor. I get a power light that goes to green then a quick very light flash of light on the screen, then the screen goes completely dark. I can not see the image with a flashlight as other posters have mentioned. Steady green light stays on. I've pulled the back of the machine and all of the caps look okay. They don't look blown at all, however the metal cover that covers the components is all black in spots, like something burned or significantly overheated. I am willing to replace components, however the list on fixya that I found does not link up to the supplier properly (mouser returns "bad request" when I do the links on some of the listed parts). So, in addition to information, I'm looking for a parts list if I need to replace parts. The parts list should be specific enough so that I can find it at an electronics parts store or online. Your help is appreciated. Thank you. Ron

Hi

Thanks for using FixYa. If the capacitors look fine then check for the power out put from the power board to other boards and to the back light inverter. I'll also suggest you to check whether the top of the caps are bulged or not & the resistors connected with the caps are also fine. You'll need a multi meter to check all of these.
Make sure that the cooling fans inside the monitor are working. If there is not enough power output from the power supply board you'll need to replace it.

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 lmistyrel@aol.com just nrth of Windy City

Display lights up then quickly goes dark


It could be your LCD backlight giving you problems. With the computer on and the monitor power LED green shine a flashlight in the lower left hand corner of your screen. Look for the ?Start? button, if your backlight is not working you?ll see a faint ?start? button if you look closely. If you do see the ?Start? button then either your backlight tube is bad or more often the inverter board is bad. Let us know if you have any other questions and please don?t forget to rate this posting.

No display


if your monitor is not connected to a pc, then it cannot find a vga signal input and therefore go into power saving mode, which is indicated by the orange light, but as soon as you connect to the pc and power on the light will go green and the monitor will power up.

Power goes green then back to standby


It sounds like this one needs component-level troubleshooting, probably in the power supply section.
