SOURCE: open the asus ul50v case

No hints. Just a disassembly pictorial guide that is real close,

http://www.insidemylaptop.com/how-to-disassemble-asus-ux50v-laptop/

Okay, maybe a few...............(lol!)

1) Always remove ALL power remove the AC adapter (Charger), and Battery.
2) Use a multi-compartment container for the various screws you will remove. Label each compartment for the area the screw/s come out of.
SOME screws look VERY similar to other screws.
Advise DO NOT mix them up.

As you can see viewing down the various photos in the pictorial guide, the Top Cover, along with the Display Assembly, is removed.
Has to be removed in order to access the Power Button Board.

In order to remove the Top Cover, the Keyboard is one of the items to remove first.
Look at Step 4.

The Keyboard Cable STAYS with the Keyboard. It removes from the motherboard connector.
Again,....Removes FROM the motherboard connector.

The Keyboard Cable is a FFC. Flat Flex Cable.
It has NO connector on the cable. The connector is on the motherboard, and stays on the motherboard.

The connector on the motherboard is made of two pieces.
It DOES NOT come completely apart!

If it is in two pieces it is broken, and you are looking at motherboard replacement.
Hence why I am being so detailed. Do not break it!

The motherboard connector has a larger bottom rectangular piece, which is the BODY.
It has a slimmer rectangular top piece, which is the Locking Bar.

The Locking Bar is wedge shaped. When locked into position in the Body, the wedge shape wedges the Flat Flex Cable, and locks it in.

The Locking Bar is Brown. All you will actually see are two tabs of it.
One tab on one side, and one tab on the other side.
Use your finger/thumbnails, and ease the tabs towards the cable itself.
(Away from the Body of the motherboard connector)

If you look close at Steps 4 and 5, you can see the brown tabs of the Locking Bar have been moved forward, and away from the Body.
The Locking Bar ONLY MOVES about 1 to 2 Millimeter's.

[2mm is a little larger than 1/16th of an Inch. 1mm is a little larger than 1/32nd of an Inch. Use a tape measure to compare, or another measuring device ]

I just searched to find a replacement Power Button Board. No luck on this end, hope you have better.

Regards,
joecoolvette

The power button is broken how to turn ontv


Hello Andrew

You didn't specify what you mean by "Broken"

Do you mean physically broken or
It just doesn't turn the tv on?
There are separate answers for each.

1:To fix a physically broken switch you could simply open the TV up and attach 2 wires to where the switch contacts are soldered to the PCB.
Run the wires to a new switch. Probably a NO (Normally Open) type. A Round switch could be mounted easily with a drill hole through an unused area of the case. Pressing a NO switch closes the contacts momentarily to trigger the digital turn On.

2:You could remove the old switch & attempt to get an actual replacement or a similar mountable switch from a components supplier.

3:If the switch is actually physically OK and the internal contacts are working (test with multimeter) then the problem is with the digital switch mode power supply that supplies power to the main circuits.

This would probably be caused by leaky Electrolytic Capacitors on the power supply PCB.
In that case, if your up to using a soldering iron and locating the Cap's then this would be an inexpensive way to fix the TV.

Good Luck

CTS 4200 4 channel CROWN power amp I changed 2 output transistors on channel 1 they were both bad but I am still seeing a fault on channel 1. I tried changing the relay for that channel but the relay...


Try changing the emitter resistors near the parts you've replaced. Also when you change out transistors it's a good idea to change them ALL out..The "supposedly good" ones may be badly stressed.
If the output line to the spkr relay has more than a volt on it the amp will stay in Protect

Frigidaire Crown dryer will not start. Has power to it


Check the following to address this issue.


1. No power to the dryer
Make sure there's power getting to the dryer. Check for a tripped circuit breaker or a blown fuse. Check the wall socket for power with a voltmeter or by plugging something else in. Sometimes the power cord disconnects or burns at the dryer, if this is the case, the wiring and the terminal block must be repaired or replaced.

2. Door switch / Door switch actuator lever
The dryer would not start with a broken door switch. Replace the door switch if found defective.

Most dryers have a door switch actuator lever - when you close a dryer door, it presses against the lever, which actuates the door switch. If the lever is broken, the switch would not activate and the dryer would not start. Replace the lever, if broken.

Note: Door switch actuator lever usually comes with the door switch assembly and it is recommended to get the whole assembly since there is almost no price difference between the door switch assembly and just the lever. Check your model for more details.

I pulled on the crown and it came off the stem


Do not open the watch yet, as you do not know how to get the stem out.
Take an eyeglass and examine the crown. You will find the small hub in the centre of the crown. If the centre of this hub is hollow and you can see the thread in it- you will be able to screw it back on stem (all watch crowns are screwed on to stems, never pressed).
If the centre of that hub looks filled with metal, then the stem end is broke and you will need replace stem AND crown (the metal filling the hub is the broken end of stem).
In case if the crown still in tact, let me know by asking questions and I'll guide you through all the process HOW TO.

Rate me, please.
