It may indicate a failure on the lcd panel, there are many ribbons coming from the panel to the various circuit boards

    If it is the panel, then i am afraid that it will be too costly to repair unless you can find a cheap lcd panel to use, but then you will incur hefty labour charges to install it, it could also be one of the data buffer boards, but the only way of knowing is to get a professional to look at it

    I was going to ask if you had Picture in picture on your set but it looks like you dont ,on that model (that may have been why you are seeing the square window) but that can be ruled out after further investigation

Your LCD panel has failed, common problem with older Samsung's and Sony's. It will cost more to replace the panel vs. buying a new TV set. If I have helped you please sign my guestbook!

It sounds that the connection between t'Con board to panel have some problems; loose contact etc. Check it. Re-seat them once, and check. If you wish to get more details about faults to Philips PFL series flat panel TVs, check this link.

How to replace both inner and outer tv screens ?


Relativity easy to do yourself, but better if you have some one to help, all you need is a Philips head screwdriver, and the replacement screens, the technical name for them are Lenticular Screen, and Fresnel, one is white, and the other is black.

You start by taking off the screws in the back of the the TV, there are screws along the top, both sides, and there are two on the the bottom right, and two on the bottom left, and there are three on the front by the power and channel and volume buttons. then grab one side and have your partner grab the other, and pull straight off.

IMPORTANT!!!!! DO NOT TOUCH THE WHITE SCREEN WITH YOUR BARE HANDS, IT IS COVERED WITH A POWDER AND CANNOT COME INTO CONTACT WITH ANY FLUIDS, INCLUDING THE OIL ON YOUR HANDS!

There are four bars that hold the screens in, one on top, bottom left and right. to remove the top, left and right you have to wiggle them loose after removing the screws.

The Black screen will go in first, make sure that the smooth side is what you will be looking at when you are done, the white screen will go right on top of it, the rough side of the white screen will meet with the rough side of the black screen.

then put the screen assembly back on, and replace screws.

I hope this helps, if you have any questions, let me know.

I am trying to connect an akai dvd player to directv, please help


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

Vizio L37 37" LCD screen screen is cracked.


I agree your screen is cracked. It's smooth to the touch because you're not actually touching the LCD section of the screen, just the protective coating. The advantage of owning an LCD TV over plasma... you can replace the screen either by going to the manufacturer or some place like e-bay. It's not a difficult thing to do if you take your time and pay attention to the details.

Good Luck
