In this situation I would check all the connections if you haven't already. I would even go as far as checking your circuit breaker to make sure you didn't trip something. Externally, it could be anything from the power button to the power cable. Internally, it may be your back light, inverter or even your connectors or other internal wiring. Based on the depth of detail in your post it is hard to tell.

Acer powerboard problem


Wow, smoke right away on the new board? Are you using a AC Adapter and Power Cord that was specifically made for the ACER or are you using one of those one size fits all that some stores sell that comes with a bag or removable tips so that one will fit your laptop? That's exactly what one of the one size fits all will do.

No matter what, you're stuck with buying another motherboard.

This is a fault solution which can be checked and corrected by you assuming that there is no component failure. There is a high possibility that the components over a period of heating and cooling, tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs or poor performance.

The best way to check for loose connections is to tap lightly when the set is powered on , If there is change while tapping then it seems that there are DRY solder joints. Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points.

Sometimes the fault occurs when the set warms up, if so you can simulate the heat using a hair dryer on the suspected areas, try with the power supply, distribution, Processor controller, driver controllers on the A/V related sections. Also the use a FREEZE-IT spray can simulate the components to cool and show up the fault.

Based on the above method you must be able to locate the area of fault and solder the sections. Sometimes large IC's- ones with more pins- tend to have drying in some pins and so cause faults related to the IC's protocol. Have a rough idea of looking into the areas to reduce the time of probing.

Check for tips to look into the SMPS unit with some of my tips:

My Toshiba Portege M200 just stopped charging and wont even turn on? Is this the battery? Or what? The charger will be plugged in the wall and plugged in the laptop but nothing?


Try removing the battery and see if it will boot without it
Then check the caharger, charging light should be green and steady on the charger itself
If it is flickering, it meand power is not making a circuit, test charger jack with a DC volt multimeter with one probe to the outer side (earth) and one on the inner (positive). If this is ok, check the charging socket is not loose (if it is, will need replacing).

After that, suspect the power strip or charging / powerboard is dead on the motherboard

I unplugged tv to move it across the room now it wont turn back on??


POE:
  1. Connect tv directly to socket without any powerboards and make sure the power cord is properly inserted (if it works than any powerboard you have been using is probably faulty)
  2. Try a different power cord
  3. See if socket is dead using another appliance. If another appliance works then the Tv is probably damaged (refer to warranty if applicable)
  4. if other appliances don't work in that socket check your fuse box.
  5. If fuse box is fine then try a different socket (if it works you may need to get an experienced person to fix the socket your trying to plug the tv into)

When i turn the tv on it would be on for 5 seconds then it would shut off how could i fix it


This is typical with many sets when it goes old as there is a high possibility that the components over a period of heating and cooling , tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs.

Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points. Please find below a link for tips on solderings

Dead motherboard


bad news - an overheated F500 is a really expensive paperweight. All you can really do is try and source a new motherboard and hope the CPU and RAM didn't go the way the board did...
