CRT sets use a special transformer called 'flyback.' This device has two, sometimes three adjustments on the transformer, one of these is a focus adjustment. All of these controls are variable resistors and these can develop internal contact problems at the 'wiper.' This problem can often be solved with some success by turning the control back and forth several (many) times to clean the contact area inside.
This is an area of high voltage but the adjustments are insulated so stray fingers may get a surprise so be careful if you try the following- - Pull AC plug from wall. - Remove the back cover; 6-8 screws, may be hex head or Phillips - In good light, look for a round peg-like control on a larger black device with a top cable running toward the side of the picture tube, with 'Focus' molded next to it or around it. - MARK the current position (correction fluid works well) - If you can identify the right control, turn it back and forth several times; most of these can be turned with a flat blade or a Phillips screwdriver. - Return it to its original position.
If the power cord can be separated and plugged into the set, turn it on and observe the picture; it may be worse than before but don't panic, you did move it. Best case is to have a mirror so you can watch the screen while not poking your screwdriver in the wrong place. This (focus) is not a potentially damaging adjustment, the other one (or two) can be since they may act on the high voltage level, focus does not. Adjust for the sharpest picture.
There are other defects which could cause this problem but the above is the most common and the others require technical background and a couple of pieces of test equipment.
If this resolves the problem, you may get many more years from your set instead of going 'flat/big screen' and being really ********** when it fails in a year or two.

Bad picture tube


Sounds like the sweep is going out. Probably cheaper to buy a new TV than repair.

My DVD player is hooked up to my RCA truflat but i cannot find the picture. I lost the original remote to my RCA truflat and am now using a RCA universal remote. How do I get picture on my tv?


There should be a button on the front of the TV that says TV/VIDEO or INPUT. Turn on the DVD player and put a DVD in it and press play. Press the TV/VIDEO button until the picture is present.

Good Luck....

You can take off the back of the tv. Look for the red wire at the top of the tube. Follow it down to the part that it goes into. On that part (transformer) there are 2 controlls. The one marked SCREEN, is the one you can turn up and watch the screen at the same time. If the tv shuts off, put that control back to the original position. If it brings up the brightness, then it is fixed. If not, take to a repair shop.
