How do i remove the black box on my screen


don't have the original remote control, I used the time warner control, I just reprogramed to control my tv without the cable box, I put the volume all the way up in the tv, then down to zero, and at the same time I hold the 0 key in the remote control, after that the screen said lamp has been reset to zero, I repeated this step because a lamp red light stayed on, after this only the power green light only stays, when installing the new lamp make sure is all the way in, you can use the white out to mark exactly where you have to push or put in the new lamp, it may not been all the way in, hope this help someone !!

Blue screen help!


The TV is fine. You need to fined the original remote. Be sure you have a cable connection on the anttenna A RF connector. Push menu and find the input. Or maybe input menu...experiment and you will find and correct this. Seen this problem years ago, can't remember exactly what the remote reads. But it should not be serious.

Full Color fading to blue then screen turns off. Repairable?


Here is what you need to do.

1.) You need to remove the entire plastic piece below the front of the screen. You most likely will find 3 screws on either side in back that you have to remove.

2.) The grill will not come out easy, pull from one side and then when it starts to come loose from the other side(there are several plastic pegs that hold it in.) Then from the bottom pull out( most of these sets have square plastic tabs at the top that tuck in.)

3.) With the grill removed locate the inspection plate behind it (it usually has 6 screws.) You will have to tilt the grill to the left and on its side as several cables are connected to it--they are held in place with trash bag like ties that you can release to get some room.

4.) With the inspection plate removed you will see a fairly small (about 3 inch square) BLACK PLASTIC BLOCK WITH SIX CONTROLS-usually they are marked with whiteout so someone can tell if they have been adjusted.

5.) You need to look very close at the block with a flashlight----usually the top three controls are FOCUS--don't touch those.
The lower three are usually marked Screen and if you look very close you will see b, g, r(blue green red)

6.)Usually the blue will be on the bottom left--it does vary

7.) Once you locate the BLUE screen control have the set on and turn it down--if the set is shutting down you may have only a few seconds to try to turn it down---usually to the left with the Blue Screen control.

8.) Best way to do this if the set is on is on a video input with nothing connected--you turn the blue down until the set stays on and then very slowly turn it up until you see a slightly blue screen with or without diagonal trace lines----if you get it to turn on this way turn the blue screen back down slowly until the blue screen and trace lines just disappear.

Let me know if you get it to work--Like I said if it is shutting down you may have to slowly turn the blue screen down a few times to get it to stay on.

I do this here for free and if this helps you at all give me a vote here--it costs you nothing.

Faint lines show up when i get dark screens in movies


First check what color of faint lines comes then reduce Screen Volts in TV of that CRT (tube)
Take off lower front cover, speaker grille of TV, there you will see focus control block that has 6 control knobs, upper 3 knobs are focus adjustment of red-green-blue CRTs and lower 3 knobs are screen volt controls for red-green-blue CRTs. Turn screen volt control knob CCW to reduce screen volts of desired CRT.
Put TV on any free AV input so screen will be dark enough to adjust screen volts.
Thanks.

Try unplugging TV while it is on and let sit for 20 minutes. Re-connect and see...
It sounds like your horzontal control is bad. It requires a new circuit board.

I just replied you and here once again...

Please pull front speaker grill and find focus block, fixed at corner having 6 control knobs on it.
Find Blue Screen control knob there.
Put your TV in AV mode to get dark screen and just press Display button on remote to have AV display.
Now slightly rotate control knobs counter clock wise until thin lines (retrace) disappear. Job is done and put back speaker grill, press display button again to disappear screen display.

Red CRT is dim....


Yes I did. You will need to get a service manual for this TV set to trace the voltage coming from the sweep power supply. If this is a problem that is new after you replaced the convergenbce4 board, you for sure have a broken wire or connection somewhere in the set. Have seen this happen may many times after a novice repairs a TV set. Good Luck
