In your case, we will want to investigate the board that the line cord plugs into. I opened up the monitor and poked around a bit. When reassembled, the metal housing sits a fraction of an inch above the sink, forming a back face. This assembly is at the top edge of the circuit board, so the housing then takes a 90° bend to form a top face. Need the approx age of the display.
Looking at the traces on the circuit board and location of other components, the capacitors could have easily been moved out of the hot spot. Answered on Jul 21, 2011 Hi, Billman11, maybe you can repair or maybe not. Together with the heat coming off the sink, it appears the engineers have created their own little capacitor oven. Can you see the power on led indicator even?? I say above with respect to the flow of air due to convection, and next to because the heat sink also wraps around, enclosing the group of capacitors on one side. That will be the smps board, or the little black box on the floor.
Welcome to Fixya Sounds like there is a problem with the inverter. If you want to try fixing this monitor you can get back to me at louie12fix on fixya or lmistyrel aol. Each lcd monitor has 2 or 3 printed circuits inside under metal shields beneath the black plastic case covers. Is lcd panel still pitch black? It happened three times in one day today, so I decided to do something about it. If you want to quickly view the content of pages found on the following pages of the manual, you can use them. .
The heat sink sits flush with the circuit board, turning the board into a front enclosing face. But that might be too pessimistic. I guess the real question is how long it will stay this way. To test the issue further, shine a flashlight to the screen once it goes black. Summary of the content on the page No.
Does the monitor have external power supply? Report back here with results! Thank you for using Fixya! Answered on Mar 16, 2011 Please check the caps in the power supply first and learn about bad caps at the links below. Look if yo can see a faint image of the screen. These capacitors seem to get almost no air flow. If you see a faint image, then you need to have the inverter replaced. After reassembly, the monitor powered right up and came online. Advertisement Print version Many people prefer to read the documents not on the screen, but in the printed version. This is either an act of gross negligence, or an intentionally created post-warranty failure point, designed to avoid market saturation.
Capacitors immediately adjacent to the affected components, but without blocked air flow looked completely normal. The option to print the manual has also been provided, and you can use it by clicking the link above - Print the manual. To avoid a repeat performance, I soldered some short extension wires to the replacement caps and moved them out to an open area of the board, being careful to give the high voltage components plenty of breathing room. However, if you do not want to take up too much of your disk space, you can always download it in the future from ManualsBase. You need to tell me some stuff first. From waht you already described it sounds like a Switch-Mode-Power-Supply failure. I found three electrolytic capacitors on the backlight inverter board were bulging, two of which had just started to leak: The capacitors were placed directly above and next to a large, flat metal heat sink.
