I have 2 lg repair the same trouble vertical horizontal rolling

Vertical or frame rolling indicates adjustment of the frame hold is required or perhaps there is a synchronisation fault.

Breaking of the picture in the horizontal plane is caused by the line hold requiring adjustment though the symptom can be connected with interior or exterior signal problems or perhaps a power supply fault, especially where both the line and frame are affected together.
It is probably a task for an engineer or at least someone with access to the servicing instructions.

RCA F27669 TV horizontal gain control

To adjust the data value to these adjustments, you have to enter the service mode option to your set. There is no external preset resistors [as in the old model TVs] for the new version TVs.
If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience.
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.
NB: Please read and understand well, the instructions to enter the service mode, before you begin. Be very careful. Note how to "EXIT" the service mode; after entering and adjusting data. This is very important.
Type in the brand name of your device, in the search box [at the top right] of the display window, and press enter to get all related posts. It will make surf easy.

My tv made a little noise and then the picture disappeared. The screen is black with a vertical line of picture approx 1/4 inch wide going up the middle of the screen. Is it fixable?

Generally this is not good news. Even in the event this TV is repaired, it will work very long. This TV has a horizontal problem. This is the most stressed area of any conventional TV. The Horizontal Output Transistor will need replace, the flyback transformer is bad, you have bad power supply with horizontal capacitors that are bad, and last, is a possible bad picture tube. This TV is not worth the effort or money to repair. Thanks for asking and show all hands of support!

RCA F27669 TV does not seem to have a Horizontal Hold. My picture has shifted about 2 inches to the left.

Generally speaking: go into the menu where you set up the colours, brightness, backlighting, etc.

Vertical/horizontal adjustments will be in there.

I can't find a manual online to be more specific.

Toshiba 27AF44 horizontal deflection problem

This type of thing is not an adjustment.

If you have any type of device that has been working properly and then it shows a change of performance, the last thing to touch is an adjustment. What you have to do is find the source of the problem and change whatever parts that are causing the failure or performance change.

In the case of your TV set, there are some components in the horizontal output stage that have changed in their specifications. This happens over time with use, age, and heat.

An experienced TV service tech can go in to the circuit areas using the proper instrumentation and troubleshoot to determine the failed parts. Then he can change them for you.

It would be best to find a service center that is experienced with, or better who is authorized to service them manufacture type of TV you have. The will have access to the service manuals and the source for the parts.

This type of problem is common caused by failing capacitors, and or the fly-back assembly, and on rare occasions the deflection yoke having some type of failure. I have also seen fault conditions in the main power supply causing this type of fault.

When you give your set out for service, it would be best to ask for an estimate. Depending on the nature of the failure, the cost can be on the expensive side.

Personally, I would be seriously considering to get an LCD HDTV the way things are going now rather than putting in a few hundred dollars to service the TV that you have now.

The average cost for the type of fault you have can run in the area of about $140 to about $280 depending on the type of failures. This is if the parts are still available.

The vertical height driver that controls the height of your picture has weakened and needs to be adjusted. If you are somewhat handy you can do this yourself. It requires that you gain access to back of the set & remove the cover. Once removed, locate the vertical height & centering adjustments. Sometimes they are located on the main board & other times are located on the color gun driver circuit board that is plugged into the end of the picture tube.

Respond to this post if you need additional assistance. Good luck!

My Sanyo DS24425 24 inch screen moves slightly to the left and stays there. its very frustrating because i play games on that tellie and cant see part. it's not parted halfway though. its like one a couple...

The problem can be corrected by only qualified technician. There is what is called the service man's menu which can only be accessed by a partciular code in service manual for that particular TV. Your local service technician should be able to locate the the manual and then perform what is caller a horizontal centering adjustment. In today's tv's there are no alalog controls for easy adjustment, it all done with eprom ic which allows the manufacturer to use the same chasis for many different picture tube sizes. If you could get manual. and have basic computer skills , you could probably do it yourself. You might try ordering the maual from Tritrinics/Cititrinix 1-800-638-3328. Scrivitron
