Streaking inside of screen

After cleaning the screen on my TV according to the Manual I have recently noticed there is some streaking on the INSIDE near the bottom right corner of the screen. It is visible only when there is bright ambient light, but I would still like to get rid of it. Is it possible to remove the front screen in order to clean this streaking?

Re: Streaking inside of screen

Philips screens tend to be very tough to remove as if you are not careful on removal of the screen frame bolts then the whole screen will come falling off.

The blue will not converge, how can I manually do it? The blue appears to be showing bottom left corner below the screen, like it got moved.

I had the same problem but it wouldn't converge on the whole right side of the screen. I fixed my problem by taking off the speaker cover, removing the 3 allen 7/64" screws from the front of the bottom of the button pannel, then removing the 4 scew from the back of the pannel (2 on each side), and the button pannel should drop down. With the power on I cleaned the 3 projection lenses with many qtips dipped in alcohol. I left the TV on so I could see if there was any streaking on the lenses (streaking means it is still dirty). Once they were all clean and I put the button pannel back on, I went to the menu and ran the autoconvergence function. Now my picture is so clean. Good Luck.

Hitachi 51UWX20B spider web like lines help

I know my response is a while after you asked, but to clean the inside of the tv case is pretty simple.

Remove the bottom speaker cover...on this model you just pull it off. There is no clips or screws.

Once the speaker cover is off you will see the bottom of the screen, there is 4-5 screws on the bottom on each side....I think 4 in the gray plastic and 1 in a black metal strap. With all of those screws out pull out SLIGHTLY on the screen and push up. The top is held in with a down force clamp and you are just popping it out of that....It will pop back in once you are done.

Now clean the back side of the screen, the mirror and CAREFULLY dust off the lenses. I myself did not want to use any cleaners (to avoid streaking) so I used a new microfiber dusting cloth. My picture became brighter and the "crack" that I thought I had was just a dust web....

Hope this helps and good luck
