Screen went black with a couple vertical colored lines


Check the tcons connections ( both flex cables and also the LVDS cable) if that doesnt solve it would suspect the Tcon as being defective. For further assistance please respond to this same post.

I posted a problem on how to remove panel but I solved it. Now as I mentioned the tv comes on goes green then black no picture just sound. I followed instructions on adjusting G screw but it doesnt work...


Its possible one of two thing have occurred, you have maladjusted the G screen control on the high voltage screens and focus assembly. Turn down (counterclockwise) all three of the screen drivers. Adjust each until a light appears in the each lens, red green and blue. Go slow or lines will appear if set too high. If all three lamps stay lit after this adjustment the look at your screen with color level down to zero using your remote and the picture menu. Adjust the three color drives to get a good black and white balance appearing on the screen. Now adjust the color level from the picture menu back up to normal range.
If you still get green diagonal lines after this adjustment then I would suspect that the green lens has a heater to cathode short in the tube.

LC-32SB24U LCD HDTV... Brand new, just out of box. Turn on, goes to language menu for about 1 second max,too fast to adjust, then screen goes black and little green led power light starts to blink. And...


Good Day, texxastam;

Do this:

1. UNPLUG TV
2. HOLD IN VOLUME DOWN &INPUT buttons on TV
3. Plug in the TV. (the TV will turn itself on).
4. A blue "K" should now be showing on the TV screen, release the buttons.
5. Press and release the VOLUME DOWN & CHANNEL DOWN buttons simultaneously on the TV. (A blue service menu will appear on the screen).
6. Using the remote, press the DOWN SELECT button once. (The highlighted line should read INDUSTRY INT (+CAUSE) OFF
7. Using the remote, press VOLUME UP once (OFF changes to ON).
8. Press ENTER. After a few seconds the screen turns green and shows - Industry INIT success - at the top of the screen.
9. Unplug the AC cord for 10 seconds then plug back in.

Good Luck, big IRISH.

PS; I did not make this up... it's from SHARP> again good luck...you may have to do this several times....too...get the timming down.

Blue out of focus; casting blue "glow"


Try changing the coolant in the blue tube. Contaminated coolant will give a halo look to the affected tube and you will experience difficulty focusing that color.Phillips/magnavox's blue is the tube most often affected with the contaminated coolant issues.

No picture, just red-blue-green lines through the middle of the screen very faint.


The PT-53WX54 is a standard projection set and does not have a bulb. It has 3 separate picture tubes. If you have lost the picture completely, not even on-screen menu, then something has stopped working in your set. It could be a video processor, vertical deflection or possibly a convergence problem. The set should be serviced by a qualified tech familiar with the Panasonic projection sets.
