I'm almost positive the problem is you have fungus in the CRTs. I know this sounds strange, but it's true. Basically there is coolant fluid in the lamps that develops fungus over time and turns yellow. It should be clear. If you take the back off the television, you will see the 3 lenses (red, green, blue) Each of the lens is held on with 3 screws. Remove the adjustable lens and look at each CRT. Shine a flashlight in they should look white. From what I've read, blue develops the problem first, then green. You can replace the fluid. Look up TV coolant replacement online. It's not to difficult, but you cannot get any of the fluid on the circuit boards or it will ruin it. Mine had a lot of fungus in the blue CRT and a little in the green. The picture looks 100% better now. Good Luck.

Hazy picture


This is listed in the standard TV area which means set has a picture tube and is not a lcd or plasma.

That being said try a rear audio and video input first to see if same issue or not.

Try to lower contrast and brightness (contrast on some sets is called picture) to see if that helps.

Lastly shoot me a model and brand.

YELLOW COLOUR IS DOMINATING


If its a Philips or a Samsung/Akai projection set it likely is contaminated Glycol causing this.

On those sets turn color off to zero or go to black and white program--if screen is mostly or all yellow Glycol is the issue---the other expert is correct that a model number and brand are needed to help you.

How do i remove the green haze


one of two issues are possible here:

Model indicated has a convergence circuit= colors are skewed or even 3d looking is convergence problem. Set has Akai name but is made by Samsung--if a convergence issue can be a do it yourself repair.

I can explain what is needed if that is the problem (see some attached photos).

The other issue seen is if on a black and white picture (color turned off) stand back and look at the screen= is it yellow looking or gray?

If yellow looking the Glycol (a cooling fluid in each tube) is contaminated- usually in these sets the blue is first= no real blue leaves a yellow screen.

Look at the photos and try to tell me which issue you have.

Akai PT5499hd that has suddenly lost color alignment


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

You can see some more examples and find a fix herebb0cf99.png http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

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

1 Answer

No Audio


The yellow, red & white terminals are composite out (old RCA connectors). Yellow is video. Red is right side audio out (line). White is left side audio out (line). You can connect them directly to any TV that accepts composite input. (i.e. Match the colors).
