A model number would help a lot...Please post it....THANKS....Smile...
PTV915 covers tons & tons of models..
Also , your description covers a lot of problem types...
Is your convergence OK ???
Are there any "halos" in the pix ???
With the color ALL the way down , does the pix look like a normal black & white pix ???
Can you take & post pix if needed ???

Sorry but I am pretty new at this TV thing. Computers yes, TV's nope. The model number is 50p8341. I don't know what convergence is really. There are no halo's just fuzzy out of focus and seems a bit on the redish in color side. If you need me to I can take a pic no problem. I turned the color all the way down and it looks like a out of focus black and white, not normal. Hope this helps, thanks alot for the quick response.

This is not something you can fix without some electronic background &/or mechanical ability...
Unlike certain computer problems where you can run a program to fix it , this requires some internal diagnosis...
You will need to do some dissassembly to determine exactly what your problem is...
Since your TV was made in 2004 , I have a good idea what the problem is...
You will need to remove the front screen...
Possibly the lower back cover later on...
If you feel comfortable with that let me know & I'll give you step by step info...


Since your pix is fuzzy , we'll worry about "convergence" later...
This link takes you to a website that shows you various "convergence" problems...

Convergence is the alignment of the 3 colors (red,green & blue) to hit the same point at the same time...

I feel comfortable with fixing it. I am just ignorant but am willing to listen and do this no problem.

Well , lets give it a try....

On the front of the TV , 2 sections come off...
The lower panel covers the speakers...
To remove it , grab at one side & gently pull it forward...
This panel is held on by velcro...
Then grab the other side & do the same to remove the panel...
The top section is the screen & requires the utmost in care as it IS VERY expensive to replace IF available....
It IS also VERY flimsy...
Along the bottom edge of the screen are 4 quarter inch hex head screws...
Use a nutdriver to remove the screws....

On the front right side is the pushbutton assembly that is attached to the screen...

While removing the screen , use CARE that the wiring to that assembly does NOT get stretched to the point you do damage to the assembly OR at the other end inside the TV...

Before you tip the screen assembly up & out to remove it , you might want to follow the wires to where they are going to & see if you find some clips to unfasten to give that wiring some more slack...
They may go down thru the top edge of the black cover panel below the screen...
IF so unscrew all the screws for that panel & track the wires to the clips & unclip the wires to get more slack...
They also may run up the inside on the right edge of the screen in which you'll have to do a balanceing act with the screen to unclip the wiring...
To do that step requires you to CAREFULLY lift the screen up & out keeping the screen close to the TV yet away enough to see where the wires are going & enough room to unclip them....
Again , use CARE....

Once you are CERTAIN that you can remove the screen WITHOUT doing damage to the pushbutton assembly , lift up on the screen & tilt it around in such a way that you can stand it SAFELY on end (Upright) against the TV WITHOUT putting stress on the pushbutton assembly wiring...


Then with a signal source (Cable , satelite dish ot antenna) , turn the TV on...

Put your head inside the TV & take a look thru the lens on the red CRT & see how the pix looks on the FACE of the CRT...
Do not worry , there is NO shock hazard doing this...

Then do the same with the green CRT (Center CRT) & the blue CRT....
Slowly creep up on the CRTs as they WILL be bright & your eyes need time to adjust...

The pix MUST be CLEAR & IN FOCUS...
IF you see a cloudy pix in the green & blue CRTs , post results...
Red should & usually does have a CLEAR & IN FOCUS pix....

On each CRT you should see skinny thin lines going from left to right in the pix...Post results...

Look carefully in the blue & green CRTs for a cloudy goo....
IF it does , you have bad CRT coolant...
Each CRT has coolant (Ethelene Glycol , the same as automobile cooling anti-freeze , only processed to be CLEAR)..


Philips/Magnavox had a problem with their coolant becoming cloudy over time...


Have fun....
