Bottle neck picture

My TV for some reason has a bottle neck picture, I mean that at the top of corners of the tv the picture curves in. The rest of the picture is fine except that the color is more intense on a normal setting.

Sounds like a bad main b+ filter or a problem in the horizontal drive circuit,such as the pincussion area. This is not a user serviceable repair.. If you know how to reoir tvs then good Luck but if your not a pro please take it to one.

Error code 0019

The error code E0019 means the waste toner bottle is full. To rest it you need to empty out the waste toner, it is easy to do.... On the left side of the copier toward the rear of the copier., there is one screw that holds on a panel. Turn the copier OFF first, remove the screw and the panel > the waste toner bottle slides out. VERY carefully pour the waste toner into a plastic garbage bag. You will see on the neck of the bottle two round spots.... Make sure you clean the inside & out side of the bottles neck. Reinstall the bottle and turn the power back ON and the code should rest.... Good Luck

Hello kcraig. I gotcha covered! :-> I am a bit bit long winded but I try to be thorough enough to make sure I help folks.Ok, lets determine a frame of reference. If you were standing in front of the copier we need to focus on the left side, lower, rear corner of the copier. There is a small panel at that lower left rear corner that can be removed with one screw. Once that panel is removed the waste toner bottle will be exposed. Merely remove the bottle and empty it. !!!!!! Please be careful as you will not harm the copier but you can easily turn your office and yourself into a huge mess since the toner is such a fine particulate that it will poof everything if you are not slow, sure and careful as you empty the bottle into a trash bag at close range. I mean it will poof big time if you are not careful, close and slow. There is no "danger" per say, just a re-enactment of of "Hiroshima as far as a big mess. That being said we can assume that you have carefully and successfully emptied the waste toner bottle. Now the next thing to do is to make sure the now empty bottle is correctly prepared to be re-installed. This is the important part. There is a " neck" on the bottle. The neck is what the copier uses to determine the waste toner level. There is an infrared light beam that shines thru the neck of the waste toner bottle and is seen by a light sensitive sensor on the other side of the bottle. When the waste toner rises to the top it blocks the light and the copier gets pissed off. When you empty the waste toner bottle YOU WILL fog the neck of tha waste toner bottle and even though its empty the copier will think the bottle is full. And if you look at the neck you will see the area that the copier is monitoring. So make sure you take a cloth and clean the "viewing area" in the neck of the bottle. Now, you will go into service mode (only techs use) but I will tell you how to. On your control panel press" additional funtions" then the numbers 2 and 8 simultaneously then additional functions again. This should be done in a smooth,timely 3 step procedure.This will bring up a new screen. Several blocks will appear on the screen but the top block will say "COPIER". Press COPIER. This will bring up a new screen that has several tabs at the top.One of those tabs will say "FUNCTION" it and then you will get another screen full of tabs. One of those will say"ERR". Press that taB and then in the lower right corner you have the option to press "ok". Press ok and then then hit the "reset" button until you return the the main screen which will of course have the error code. At that point unplug the copier, wait 10 seconds or so and then plug it back in. U R fixed! :-) give me a good grade please and take care. ......SPINAL

The solder could be loose in the CRT board witch is at the end of the picture tube neck,before you take the back cover out try a simple test put your forearm in the face of the picture tube and the hair should stand with the tv on that will mean you do have high voltage going to the picture tube but if the hair in your forearm does not stand with static it means the picture tube is missing high voltage and then reason for that is not necessarely a loose conection but a bad component in the main board.If you not familiar with tv service be safe and call for assistance.
