Screen black I am connecting to my monitor with a Joytech component cable every once in a while the screen goes blackbut audio is not lost. The picture returns in about 2 seconds.It is a new ps3 should i return it.

seems like a problem with graphics adapter.

Hi Juan,

Just bought one of these,

R138 is a 27 ohm (red purple black gold space brown), 1 watt, metal film, 1% tolerance resistor.

Hope thats all you need to get your display up and running!

White screen when you start the laptop, and then when you connect an external VGA monitor, you can only operate in Safe Mode?

Or white screen except when you are Safe Mode?

Doesn't matter anyway, just wanted to see what you are stating.

1) Have you connected an external VGA monitor to the laptop, and seen if you get a good display on the external VGA monitor?

No display on external monitor?
You have at least 3 display options available;
A) Internal monitor of laptop ONLY
B) Internal monitor of laptop AND external VGA monitor.
C) External VGA monitor ONLY

Hold the Fn key down, and tap once on the F5 key.
(The F5 key is the Display Toggle-Over key)
Still no?
Hold the Fn key down again, and tap once more on the F5 key.

Good display on external VGA monitor?
Problem is the Video Cable, or inside the Display Assembly.

White screen on external VGA monitor also?
Problem is the graphics chipset.

[Actually it is probably inadequate cooling for the graphics chipset, and this makes a bad contact of graphics chipset TO motherboard. If this is found to be the problem I can explain further, and in much more detail ]

Inside the Display Assembly:

A) Screen Inverter if it is CCFL backlighting.
May or may NOT be a screen Inverter if it uses LED backlighting.

[ CCFL - Cold Cathode Fluorescent Lamp
LED - Light Emitting Diode ]

B) LCD screen.

Video Cable:
The Video Cable connects to the motherboard, in an area either under the Keyboard, or under the Switch Cover, or bottom of the laptop.

[Switch Cover,
Goes by many names. It is the strip of plastic above the Keyboard, and below the LCD screen. Usually has the Power On button, and LED indicator lights; plus speakers, sometimes ]

From there the Video Cable goes under the left Hinge, and up into the Display Assembly.
If a screen Inverter is used, a small cable comes from the main cable, and plugs into the screen Inverter.
The main cable connects to the back of the LCD screen.

Due to normal repeated opening, and closing of the laptop; the Video Cable may be pulled on.
This can create a bad connection on motherboard side, and/or screen Inverter cable connection, (IF used), or to the back of the LCD screen.

It can also cause damage to the Video Cable.
(Stretched/Broken wires)

Once you post the product number I can guide you step by step, show you the components I'm talking about, and track down a Service Manual link, and possibly pictorial disassembly information.

The Video Cable connections are checked first.
A loose connection can cause what you are seeing.

The sheath of the Video Cable is also scrutinized for damage.
Obvious damage to the sheath, may mean damage to the tiny wires inside the Video Cable.

Another thing that can cause what you are seeing.

Video Cable connections prove not to be the problem, then the Video Cable is to be removed, and a continuity test performed on it.
Multimeter set to OHM's. (1K)

If a multimeter is not at your access, then suggest taking the Video Cable down to the nearest small computer shop, and have the resident tech check it for continuity. Should only be a couple of bucks.

YOU MUST rule out the Video Cable as the problem, before going on.

Video Cable checks out?
Then if a screen Inverter is used, this is the next component in the diagnostic flowchart.

Problem is this; it requires a sensitive multimeter to test a screen Inverter. Think fairly expensive,

http://www.fonerbooks.com/test.htm

The plastic frame in front of the LCD screen, is the Display Bezel.
The screen Inverter is located behind the Display Bezel, and mounted down towards the bottom of the LCD Screen Frame.

Due to the multimeter issue, the above noted ease of accessing to replace, and the usually low cost of the screen Inverter; most decide to just replace.

Screen Inverter replaced? Same problem?
The problem is the LCD screen.

No screen Inverter used? The problem is the LCD screen.

Video Cable; Usually around $9 to $20
Screen Inverter; Same.
LCD Screen; from $70 to $240. Just depends on what Lenovo laptop we're talking about here.

This is why you diagnose first.
Would be foolish to assume the problem is the LCD screen, and purchase one; when the problem may have just been a loose Video Cable connection, or one of the $9 to $20 components stated above.

Ready to diagnose?

Check whether the cable from the system to the screen is connected properly and there is not loose contact. Also take the system into BIOS and check whether the same issue is happening in the BIOS screen.Try a factory reset on the screen by pressing the OSD button on the screen.
Switchoff the screen and disconnect all teh cables including the powe cable and press and hold the power button for around 40 sec and now reconnect the cables and try to power up the screen

check your vga cable that is connected on your cpu,for some lose connection,it must be fitted if you still don't get any display check your cpu.have some other monitor for isolation,if you dont have bring it on s repair center,your cpu has a problem.

it happened may b due to inproper power supply.So check the monitor data cable & other connections also.

If you've connected an external monitor to your computer and the image is coming up fine then that means your video card on the motherboard is good.

The only other parts it could be is the LCD Flex cable that connects to the LCD screen to the motherboard, the LCD Inverter that powers the LCD screen or the LCD screen itself. Usually you can find a used screen that is complete with all those components on ebay.

ruettab,

good day. to connect your any DVD player to any TV screen always remember this color code

from DVD back part:

yellow = video out

red/blue/green( in a row) = component video out ( this can only be used for screen with component video inputs)


Black = digital audio ( rarely use unless)
Red and white (in a row) = Audio output (left and right audio)


where to connect from TV screen.

Locate where A/V INPUTS (audio/video socket) from your TV screen, you can see it either at the BACK/SIDE or somtimes in FRONT of TV screen , having marked as "AV1"AV2"AV3' .

Once you found TV input, you must first have RCA cable (color code cable to connect player to screen) then connect the RCA cable at the back of your DVD player, simply follow color code

RCA yellow marked cable = DVD yellow socket
RCA RED and WHITE marked cable = DVD RED and white socket (second row for your player)

then connect the other end of the RCA cable to TV screen, first select which input where you gonna place the DVD player ( either AV1, Av2 or Av3 if do have multiple inputs)

once decided which INPUT to connect the player.
ex. if you select AV1 as input there would be 3socket on its row (yellow/red/white)

now connect the other end of RCA cable to the screen by following the same color code:

RCA yellow cable = TV screen A/V1 input yellow socket
RCA RED and White = TV screen A/V1 input red and white socket.

cheers,
mark

It is the Monitor Cable connected to the CPU cabinet is faulty. Please check out the cable and its pin firmly.

Try to find the fault, may be the cable broken or tear up.

Let me know if further diagnose required.

Have a nice day.

problam can be with cable, screen, or xbox. try replacing cable first, it is the cheapest and therefore can save you alot of pain. if another cable doesnt solve it, try hooking xbox with another screem (TV or something), if it works, its a screen problem - check for overheating. if it doesnt, you got yourself a messed xbox im afraid.
