Question about Acer Aspire 5500 5570-2609 Laptop

Open Question

Problem with the logic board marked as 0171-2242-0153 and

I have Viewsonic VG150,

Problem with the logic board marked as 0171-2242-0153 and
3150-0122-0150 by means of silk screen on green PCB, looks original by
the fab house. Also E11131070 is printed on a white sticky label,
affixed at a later time.
The issue is that my VGA image is fuzzy, with white horizontal lines
from top to bottom. You can still see the payload image behind the
white horizontal lines. The lines seem pretty stable with just slight
Using deductive logic, I condicted more tests and observed that the
built-in menus (generated internally) for contrast, monitor info, etc
are perfect. No lines at all. The lines show up only when VGA signal
is present.
So I deduced the issue is on the analog part, close to the signal
connector - bad pre-amp, bad gate, etc.
Not having schematic I figured the first hit is the Mitsubishi
M52743BSP chip. Ok swapped it out (yay $5 at Newark) but my lines are
still there and my built-in menus are clear and stable.
I see few AmTran ICs, some a good suspect but I though I should
increase my IQ approach in troubleshooting this issue.
Any help?

My laptop lg x130 stuck for almost a month when i turn on it the screen has no display

The display of your laptop is one of its most integral components, and if it is exhibiting problems, it is one of the most frustrating issues you can experience as a computer owner. A display can experience a variety of issues, from the mildly annoying flickering of a screen, to it not powering on at all. Identifying the problem is the first step towards assessing whether it can be fixed, or if it is time to get a new computer.

  1. Brightness
    • If the brightness of your screen is intermittent, or is flickering, it is likely that the inverter is broken. The inverter is a small board that controls the brightness of your screen. It plugs into the display and the motherboard, or the main brain of your computer. Try a new inverter board, which you can get from your computer manufacturer, or from a computer supply store, by taking out the inverter from your display casing.
    Garbled Video
    • If there is garbled video on your screen, it may mean that the low-voltage differential signaling cable, also called an LVDS cable, has begun to malfunction, or that the graphics card is failing. To check your LVDS cable, open up the computer and unplug the LVDS, which will be running from the motherboard up into your display. Plug the LVDS cable back in and with the computer open, turn the computer on and check the graphics. If it continues, you may need to take the display out of its casing and unplug the LVDS from the back of the screen. If the graphics issue continues, try another graphics card. If the new graphics card is in, and there are still graphics issues, the LVDS will need to be replaced.
    No Video
    • If there is no video on the screen of your laptop, it can mean one of two problems: that the display has completely given out, or the logic board is not supplying any video to the screen. If there is no video, try moving the screen forward to back several times to see if video appears momentarily. If so, there may be a loose connection. If no video comes on, hook up an external monitor to the computer and see if any video appears. If video does appear, it is likely the screen has died. If there is no video, your graphics card has failed. Depending on the logic board holding the graphics card, you will either have to replace the graphics card, or the whole logic board.
I hope you find it very helpful. Best regards.

Hi there, i cannot find a motherboard for my lap top..

A motherboard is the central printed circuit board (PCB) in many modern computers and holds many of the crucial components of the system, while providing connectors for other peripherals. The motherboard is sometimes alternatively known as the main board, system board, or, on Apple computers, the logic board.
It is not a separate board like a key board or any others. Its image is like he one below
You can not access it till you open the computer. It should be always opened or inspected by a computer engineer

Does the PCG 8131L have a cmos battery? If so, where is it? We can't find it on the motherboard.

They are usually right along the front of the laptop so best way to get it to die is to remove all power sources for a few days/weeks and have it die out.

- Notebook Pavilion dv2000 black screen will not boot up. Power comes on and keyboard only.

The issue is usually caused by broken solder connections between some chips of the logic board and the PCB itself. There are two ways to fix this problem. If you'd rather not install it yourself, you can have a third party laptop repair service do it for you. If you prefer to do it yourself, you can reflow the GPU (repairs the solder connections) or replace the logic board alltogether. If you want to replace it, get the part and ebay and use a Laptop repair guide that teaches you how to install the part yourself. If you want to reflow, Google how to reflow a motherboard and you will find ways to re-heat the board to repair the solder connections, chances of success of DIY reflow are around 50%.

Only have half screen on my Dell Inspiron 1501

What your describing is a failure of the LCD or possibly the inverter cable connection to the LCD. Most likely an LCD replacement will be required.

LCDs run around $150 on Ebay
