Question about Panasonic TH-50PX60U 50 in. Plasma HDTV

TH50PX60U screen issue

Hello,

I have a TH50PX60U and the screen is damaged. Not the external, the layer beneath, it appears to be a mesh-like material (hard to tell). I have a back-ground in electronics and if I could identify this, I would order it and attempt the replacement. Any ideas? I am also looking for the service manual, from what I understand, Panasonic wants $30, I am looking for the freebie though.

It would be so awesome to get this up and running, any help would be greatly appreciated.

If the screen is cracked (glass is broken ) you will have to replace the panel at about 1200 to 1500

The picture has began to flicker as though someone is shining a flash light on it, the picture is unsteady and a band has appeared at the bottom of the screen


Sounds like it's drunk

No really,..........think about it a minute............
Someone is shining a flashlight at it - Cop
The picture is unsteady - Drunk
A band has appeared at the bottom - Things a drunk sees

Sorry................you just have to have a warped mind like mine


Diagnose.......

1) Graphics chipset
2) Video Cable
3) screen Inverter -> IF USED
4) LCD Screen

I abhor posting generic one-size-fits-all information.
Post the laptop manufacturer name, and model number in a Comment.

This can be found on the Bottom of the laptop.
For example on a Compaq or HP laptop, there is a white Service tag on the bottom.
Product Number is what is needed. P/N = Product Number.

This way I can guide you step by step. It's confusing enough with exact information being given to you, much less pile a bunch of not needed info with it.

Diagnostic flowchart:

Graphics chipset. An external VGA monitor will be attached to the laptop, to check.

Video Cable:
Connections can come loose. Video Cable may have received damage.

screen Inverter:
A small circuit board mounted to the bottom of the Screen Frame, and behind the Display Bezel.

[The LCD screen is an assembly. It is composed of layers, and these layers are held in the factory set position; by a metal Screen Frame. Resembles a picture frame.

The plastic frame in front of the LCD screen, is the Display Bezel ]

LCD screen:
No explanation needed here.
This is the LAST component in the diagnosis. If everything ELSE is good, then this is replaced.
NOT replace LCD screen first!

My toshiba L35-S2161 the monitor only displays lines in colors, what to do to fix it


Since you diagnosed by using an external VGA monitor, you now know the fault lies in either the Video Cable, or the Display Assembly.

Your graphics chipset is good.
(Also known as GPU. Graphics Processing Unit )


A) Video Cable:
(Toshiba = LCD FL Cable )

See if the connections are good. Check the motherboard side connection of the Video Cable, AND the LCD screen side connection.

A loose connection can do this.

1) http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L35/taking-apart-laptop-1.htm

2) http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L35/remove-notebook-screen.htm

(On both links above you can click on the photos to enlarge )

Observe the sheath of the Video Cable for obvious signs of damage.
If the cable looks pinched, stretched, or torn, the tiny wires inside the cable may be damaged also.

Best method is to remove the Video Cable, and perform a continuity test of the wires inside the cable, with a multimeter.
(An economical unit can be purchased for around $8 to $12.
Analog or digital is fine )

B) Display Assembly:

Video Cable checks out OK;

1) Check the connections to the screen Inverter board.
Make sure they are tight. Make sure the Inverter board does not appear to be damaged.

2) Screen Inverter board:

Primer;
An LCD screen does not produce light. It needs an additional light source.

http://en.wikipedia.org/wiki/LCD_screen

A Backlight is the additional light source.
A Backlight is usually a CCFL, or a series of LED lights.

The Toshiba Satellite L35-S2161 Notebook PC, uses a CCFL for a Backlight. (Uses 1 CCFL)

CCFL stands for Cold Cathode Fluorescent Lamp
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

(Average size is 2mm Thick, and is close to the width of the LCD screen in question, Long )

A screen Inverter converts the power (Electricity) from the laptop, for the Backlight and LCD screen.

It is located behind the Display Mask, (Display Bezel), and mounted towards the bottom of the LCD screen.

http://www.zkarlo.com/selected-zkarlo-part/inverter-board-p2215.php

A bad screen Inverter usually causes a garbled display, or doesn't light the Backlight up.

To test a screen Inverter you need a sensitive multimeter, or use a spare Backlight bulb that is known to be good.

Bulb lights up the Inverter is good, the Backlight in the LCD screen assembly, is bad.

[ The LCD screen is composed of layers. These layers are held in place by a metal Screen Frame. {Resembles a picture frame }

The Screen Frame comes apart.

Screws are removed, and the Screen Frame comes apart in four pieces, (Four sides), or the Screen Frame comes apart in two pieces as an Upper half, and Lower half.

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L35/big/satellite-L35-screen-08.jpg

The Backlight bulb is taped to one side of the LCD screen layers, and is under that side of the Screen Frame.

The LCD screen layers MUST be kept aligned, as they were from the factory. For this reason alone, it is tedious for an experienced technician, and is usually not done at the consumer, or DIY level.

I have a acer 4740g laptop.I ve got display problem.It shows several lines and i cnt work on it.Recently it got little pressed on its display.Can any1 help me?


Hello shreejan_man

First thing to do is to test the screen. Also you have not mentioned if there is any cracks or damages.

Plug the laptop to an external monitor (any type will do). If the display on the external monitor is OK then it means the laptop screen is damaged.

If the display on the external screen is the same as the laptop then the problem is internal with the graphic chip or the video contacts.

this laptop is not that old since acer released this model last year. Check you warranty status on it. Some acer laptops come with two year warranty. Check the laptop carefully, if there is no sign of physical damage, (cracks, chips ...) then take it back as a warranty issue.

Good luck
please leave comment, vote if this helped.

Broken lcd, how can we go about it.


Call HP to determine if the unit is still in-warranty, and they will be replacing it. Otherwise, you may have to upgrade it through their Out-of-Warrranty programs.

Hello, I have an Acer Aspire 1356LMi laptop. It


This problem is mostly likely with your LCD screen. It needs to be replaced. I suggest you connect your laptop to an external computer monitor and see if you still see the same issue on the external monitor. If you don't see it, then for sure it is not your motherboard or graphic chip. It has to do with your screen. In rare cases this can also happen if your wiring for the LCD screen is going bad or damaged.

Once you connect the external computer monitor to your laptop, turn your laptop on and located the "FN" and "F4 or F5 key depending on the laptop model" key on your laptop. Hold FN down and hit the F4 key once and see if the screen switches to your external monitor. If not, hit it again and wait.

Some newer laptops auto detect external monitors when they are connected to one.

Crack beneath screen


I hate to bring bad news but it's better cruel truth than sweet lie.
You got so-called "physical damage" of your LCD panel. Surface that you can touch and one that looks intact is just a protective layer. Behind it is fragile class of LCD panel. Sometimes kids tap toy into the screen and parents later guessing what's wrong with TV.
No manufacturer (that covers first 12 months) or extended warranty will cover this repair. Technician will show up for free of charge, take a pictures of the screen and leave you with this problem. Whole LCD panel have to be replaced and part alone could cost up to 80% of cost of new TV.
Unless you can prove that this is shipping damage (I doubt it because it is not that you calling retailer very next day after purchase) - there is nothing that you can do to get out of this situation cheaply.
Still you need to call manufacturer customer service and have technician from authorized service center to show up and inspect it. Maybe we both wrong and you have a case of defective panel. Really hard to determine without seeing pictures of how your LCD looks like.
Sorry again and good luck!
Russ.

I cant use my lg external dvd drive on linux mint 7.


hi mcasey82,

Yes lg external dvd drive would work with just about any latest linux distribution, if your user account is a member of the plugdev linux groupthe drive will automatically appear on the desktop after you plug the drive from the usb slot

you can verify the plugdev group members by issuing a command cat /etc/groups from the command terminal
user@localhost# cat /etc/groups | grep plugdev

if your current username is not a member, you add by issuing a usermod command
user@localhost# usermod -g plugdev username

"E1" problem


Hi,

I would request you to please check at both ends of the drain hose and confirm that you do nit have a leak. Also, please confirm that water is not leaking directly under the dishwasher.
If you are certain that you do not have a real leak, check the impeller (under the mesh filter in the sump area beneath the lower dish rack) is not damaged and is firmly in place.

The E1 error code is a Leakage Error, detected by the motor spinning faster than it should if the unit is filled with water.

Hope this helps resolve the issue.

God Bless
