Re: Have A focus problem.

Sounds like your yoke is not adjusted. The yoke is made up of magnets and must be alligned one color at a time.

Picture goes dark but there is sound

There are many cause of dark picture symptom of standard television.First thing to do is try to adjust the screen control adjustment located at the flyback at the lower parts.There are two flyback adjustment the focus and screen adjustment.The upper level is focus and the lower is screen control. If check also the CRT socket board section.This CRT board is compose of high voltage terminal coming from the high voltage supply.Check if there's a cold solder in CRT socket terminal and other parts around the CRT socket.The heater supply,the RGB cathode supply,and the screen supply are the supply of picture tube to be lights up.So try to resolder those parts of the TV.Avoid short circuit in the PCB board.Hope it will help you.Thanks..

I have a RCA 32V432T 36in...the screen is light blue with white horizontal looks like a film in front of the actual picture...there is still audio though. what's going on?

There are two main causes for this fault. The first one is, advanced screen voltage to the screen grid of picture tube. The second one is leaky blue video output transisotr.
Just open your TV, and locate the screen control. It usually can be located with LOT [Line Output Transformer]. There will be two adjustable controls integrated to this LOT, marked as screen and focus. Out of which, the lower one will be for screen adjustment, and the upper one for focus adjustment. Just rotate the screen control [the lower one] to a little counterclockwise, so that the thin horoizontal lines on the screen just fade of. Adjustment is critical and should be done with care, and a small movement may just be enough. If it does not help you, repalce the blue video output transistor. This part can be located at the bace card [the printed circuit board fitted to the neck of the picture tube]. Locate it, replace it. OK.

Pix is dim and too big for screen

Your TVs focus voltage has some trouble. You gets an out of focus piture now. There may be two reasons for this fault. The first one is, the focus pack trouble. The second one is picture tube base socket trouble. Both are repairable.
Focus pack is integrated with Line Output Transformer [LOT], and picture tube base socket is soldered directly to picture tube base card. You just open the TV and check whether there is any "Shhhh" sound comes from the neck side of the picture tube while tv is working. If it is so, you will get a smell of Ozone gas also. If it is so, switch off the set and unplug it from mains socket, pull out picture tube base card from the picture tube neck. Be gentle, and not make any shakes while pulling it out. The neck part of the picture tube is very thin relative to its other portions of the picture tube, and have a chance to break. So be carefull when you pull it out. You can see the base socket soldered directly to it. There will be two wires also, for some sets only one, attached to it. Normally the red wire going to a slot in the socket is focus wire, through which focus voltage reaches to the relative pin of the picture tube. Just detach the wire out from the socket, desolder it out and go for a similar type, and pin confuguration. Replacing it will solve your problem. After replacing the picture tube socket, a slight focus adjustment may be needed. Sometimes may not. The focus voltage can be adjusted. Its adjustment control is located on the above said [LOT]. There will be two adjustment controls, marked Focus and Screen. Out of which the upper one is for focus adjustment, and the lower one is for screen adjustment as its markings states. You just adjust the focus control very little, while watching the picture on your tv screen. Take menu display for reference, rather than moving pictures for focus adjustment, so that you will get a stationary image for reference.
The second stated trouble is related to the screen-focus pack integrated with the [LOT] itself. If it has got damaged, there is no other way than replacing the [LOT]. If so desolder it out from the circuit board, after detaching the anode cap from the top of the picture tube,and focus and screen wires. Before detaching the anode cap, care must be taken, as there may be some extra high tension voltage charge on the final anode of the picture tube, which is dangerous. You must discharge it before unpluging it, otherwise you may get electric shock from it, even after the Tv is switched off and unpluged from the wall socket. The charge may retain there for hours. So be careful.
If you have any more doubts, inform me through Fixya. Ok.

Lines on the screen

If the lines are thin and spreaded allover the screen from top to bottom, and are equally spaced around one inch of so apart, it will be a screen voltage rise problem. You just decrese both brightness, contrast and colour contols of your TV to zero position, and look into, where there is lines are visible on the screen or not. You should notice this in a drak room, so as to see is well, or close all the doors and windows to make the circumstance to a little bit dark.
If you can see these lines still, it is clear evidence of the above said fault. To rectify this fault you should open your TV. Open the back cover of the TV, and you will see a Line Output Transformer. It is otherwse known as LOT. It can be recoganiized easely as it its size. Normally it will look black in colour and a thick wire from it goes the picture tube's final anode, and look like it is stcked to it with the help of a rubber ******. Other two wires from it goes to the picture tube base board. These two wires are, one for focus and the other for screen.
There will be two controls on the lot, which can be varied, and seem to be integrated with LOT. Among, upper one is for focus adjustment, and lower one is for screen adjustment. Both will be marked as "Screen" and "Focus". You just find out the screen control. With the healp of a screw driver it can be adjusted.
Keep the TV on, Brightness, Contrast and colour to minimum, adjust this control to a little [ a very little movement should be done, otherwise the picture will be get blurred], to just eliminate the lines you see on the screen. Focus control and screen controls are interactable, that is adjusting one may effect the other. After eliminating these lines just up the brightness and contrast control to at about their mid position and press the menu button on the TV or remote control to get the menu screen. Look at the letterings, and if it seem to be out of focus only, just adjust the focus contorl to get well focused captions. The adjustments are hot, that is while the TV is operating. Take care. Ok.

Is there a focus for my F19251GY TV

Yes, of course there it is in every TVs. The focus adjustment in TVs determine the clarity of the display. It is a service adjustement and if you want to adjust it you should open your TV. It can be located at the Line Output Transformer [LOT], and integrated to it.
There will be two adjustable controls can be seen on the LOT. Out of which one is Focus control, and other is Screen control. Both are marked. Normally Focus control is placed on the top side and Screen control to bottom. Both controls are interactive, that is adjusting one will effect the other a little.
If your TV is out of focus, you just open its back cover and locate the said control. It will be usually marked as focus. Adjust a little while looking at picture to get a well defined focus. For this adjustment, take its menu display as reference rather than a moving object. Adjust it to get a well defined display. Place a mirror in front of your TV, so that you can see the image on it from back side.
A defective CRT [picture tube base] "socket" may also be the cause out of focus picture. It can be located on the base card of your TV, and can be detached from it desodered. If the above said adjustments did not give any results, the CRT Base may be defective. If base socket is defective, you can hear a very slght "shhhh" noice from it as you advance the focus control. Try to find out and rectify the problem. Ok

TV has fuzzy piture, all colors, but contrast is awful

I think you'd have to look at how much a comparable set would cost. I know that flat screen sets are coming down in price.

One thing you could try is to adjust the focus control although if it just went all of a sudden, then this may not help. There are two controls on the flyback transformer. Follow the thick red wire from the top of the picture tube down to the transformer that it's connected to on the circuit board. There will be two controls, the upper one being focus (marked with an "f" or the word focus). Try adjusting this while watching the picture. A mirror may be helpful. At the same time, be very careful what you touch in there, any metal part could have high voltage on it. As long as you are just touching plastic parts you should be ok. A good rule of thumb is to keep one hand behind your back as you work so as you don't inadvertantly ground yourself to the chassis while touching something with a high voltage on it.

If this scares you a little perhaps it's worth taking the set to a shop for an estimate.

I have a Zenith C27A24T the picture is out of focus.

If there is no other problem, he probably touched the focus adjustment in the back of the set. Open up the back and locate the flyback transformer (part with large red wire coming out the top). There will be 2 adjustment controls on it. One should be labeled screen, the other focus. Adjust the focus until crisp.

Blurry picture

You probably have a focus problem. Possibly the focus control has opened. If so, then you would have to have the Flyback (High Voltage transformer) replaced. The control is integrated into the flyback. Depending on the labor chages and parts prices would determine if you want make that kind of investment. Other problem can also cause this effect such as a bad picture tube, open resistor,bad picture tube socket, etc.
