The TV is only showing half of the picture I have a Panasonic TX32 PL10 100HZ tv. I havent moved or banged into it but am getting the same problem as above. My tv turns on ok if left for a while, but after a few minutes it loses the top half of the screen with a white line where the two join. The picture does not move or flicker.

MY Panasonic TV Model TX -33P100X showing half picture and half black screen. When switch off and on again sometimes the picture reappear.


hit your TV on left side or right side or on top & then observe ..........you will get normal picture or it comes & again it goes....if it is happening like that then following is the situation..........after 4 or 5 yrs in some TVs on main board ( also on CRT circuit board ) at some soldering joints crack develops....then due to loose contact picture becomes small in size or abnormal width, or rolls etc ...........when we hit that lightly then those loose contacts joins temporarly & again picture appears normally for some time............so solution is .....TV main board & CRT circuit board should be observed carefully & most of the joints should be re-soldered.......only a good service engineer can do that........even after hitting TV lightly if there is no response then main board has to be checked completely........in your case iam sure it is loose connection problem.........joints should be re - soldered ...100% it works again ................this problem cannot be solved by user unless user has idea about components( resisitors, transisitors, diodes,...etc) , have soldering iron , multimeter & other tools....................so contact good TV service engineer & just ask him to resolder joints ...........

Panasonic TV picture shrinks to a line


There is an IC which controls the vertical deflection and over the course of a few (or 8) years with the set heating up and cooling off some of the connections work their way loose causing the symptoms you describe.
If you were to bang on the side of the set you could likely "pop" it back in but this is not a good solution. The vertical IC needs to be re-soldered. This is especially common in Panasonic sets. About 10 minutes with a soldering iron should have it worked out.

If you're handy with a soldering iron I can tell you what to look for.

The TV typically works fine, however lately without any prompting when turned on sound is there without the picture. Turning the set on/off repeatedly used to help and eventually the picture would appear....

The television once on has good picture then black rectangular blocks the bottom half of the screen showing only half the picture, very annoying. how can i fix this myself?


look for the vertical section of the printed circuit board.there is a vertical driver ic and it is maybe bad...... either the soldering,or the ic.
if you bang on the tv and the picture regains deflection,there is a bad solder joint or connection.
there are a few capacitors too 100mf 25 volt 4.7 50v also 22mf at 50v

Tube TV-sound ok, no picture sometimes


Hello,

You do have a loose connection, you can take the back off and try to look for a cold solder connection or a crack someplace on the circuit board. In any event the section to concentrate on is the HV section of the TV.

I wish you well in finding the connection. You will need a soldering iron and solder once you find the problem.

One other option is that you can just donate the TV to a vocational school and get a tax write-off for next year.

I hope this helps,

Thank you,

Sony tv problem


You have a loose solder connection or two. If I knew the model number of the set, I could be more specific. I would expect the repair would run about a hundred dollars, so make sure the picture quality is great before going to the expense.

The TV is only showing half of the picture


Hi Bigtate,

There is not much for me to go on with your description but here goes,

I suppose you have a convential TV set with a glass picture tube and not one of the new types with the large screen slim style displays!!!

If it a glass type picture tube then the following assumptions are made.

I hope yopu have not shifted house recently and moved the TV around???
If you have its possible the Yoke (its a device on the neck of the Picture tube that controls magnetically the scanning dot) may have moved and only is letting you see half a picture...
This is a long shot but it could be the cause..

Now the picture is supplied to you by a fast moving dot of light (Black & White set) that scans from the top of the picture and moves very fast down to the bottom of the screen, then flys back to the top of the screen and starts all over again during this process the dot lights up the picture tube to provide you with
the picture you see... (On a colour set there are three dots)

Its quite a complex process and its all controlled by electronics inside the TV receiver.

If you are getting only half a picture then something is causing the dot to only turn on for the lower half of the picture during its write time to the glass screen,

You dont say if the half thats off is white or black, so there are many things that the service technician needs to know before even starting to look for this fault. During the dot doing its write cycle down the sceen, when it reachs the bottom and flys back to the top of the screen it receives a synchronous pulse from the TV station, and this TV signal is critical in making sure you see the same picture as is being sent from the TV station.
Sometimes this sync pulse from the TV station is very weak and so your picture may float up and down the screen trying to lock to the incoming signal.. this just may be your fault.. but you dont say if the half of the picture that you see is floating or not..
Your situation may be that your TV has partially locked to the station signal and your aerial may be problematic,
but then you dont say if its on just the one channel or all of your station channels. So there needs to be more analysis of your situation prior to a positive answer being provided....

Sorry I can be of more help...

Sony Trinitron KV-32S40 32" TV problem


This is a simple and common problem. The solder joints on the vertical output IC have cracked loose. I actually did a housecall on the exact same set with the exact same symptoms this morning! A good tech will resolder the pins of the vertical output IC and all other major solder joints on the main board and the set will play fine.

Picture on Panasonic tv intermittently becomes striated and bottom half of picture shows on top half of screen


Hello! What you're describing sounds like a vertical deflection problem if it also occurs when you're watching a TV program. This type of trouble is a component failing in the vertical circuit of your set. A loose solder connection could cause this. On the other hand, if it just happens when you run the VCR, your problem could be somewhere in the tape drive mechanism or possibly a bad tape. Things like slipping clutches,bad belts sticking guide rollers are a few things that will cause this in a VCR. You need to have a tech check it for you. Hope this gives you some help. Stargazer
