Question about Sony KV-36XBR450 36" TV

1 Answer

Half a picture

After several months of sitting, I recently relocated this tv (no drops) to another location, but now have only the bottom 2/3 of the picture on the top 1/2 of the screen.There also seems to be a bit of a squeeze of the picture towards the center of the tube. I tried several different inputs i.e. DVD via s-video and off air tv through the coax input.The color and display seem to be okay, just shifted. There doesn't seen to be a knob for the horizontal hold. Suggestions?

Re: Half a picture

Dont use the set and call a service tech,you might have loose conections in the horizontal circuit,if you keep using it for this problem it might become worst.

FOLLOW this steps and fix it. God bless you

  • 1
    Power down the TV. Let it cool down for several minutes to avoid touching anything hot. There are many parts inside the TV that could be hot.

  • 2
    Unplug the TV and all media devices attached to it. Let the TV sit again for several more minutes just to be safe. The lamp receptacle and other components could still be hot.

  • 3
    Unscrew the back cover of your TV with a screwdriver. Have someone help if the cover is big. The lamp's housing unit on most TVs is located towards the bottom. Refer to your TV Owner's Manual for specific instructions.

  • 4
    Unscrew the lamp's housing unit with your screwdriver. Take your time to avoid damaging the housing unit. You'll see the lamp once you open the housing unit.

  • 5
    Use a soft cloth to unscrew the lamp out of the housing unit. There's a possibility the lamps- could still be hot. The cloth will help protect your hand.

  • 6
    Screw the replacement lamp into the housing unit with the same soft cloth. The oils from your fingers could ruin a rear projection TV bulb.

  • 7
    Reattach the lamp's housing unit and TV back cover. Make sure no wires are loose or get caught when screwing the back cover on.

  • 8
    Attach all media devices like cable or satellite boxes. You should now be able to watch your TV with a brand new picture.

Top half of picture is black bottom half of picture is fine

The problem is in the vertical output ic, located near the high voltage transformer, "heat sinked" the pins need to be resolded or the ic replaced along with two or three capacitors. If a professional gets involved I recommend an estimate.

No Audio

Most likely it pulled hard enough to cause some bad solder connections on the botton of the 4 pin...try to unsolder and resolder the connector and reconnect the speakers this should fix you up.

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...

Sometimes several channels will have the same ghost-like picture. the above all problems are due to one that is weak signal. 1 check for antena or cable or satellite input is ok or wire might be defective due to old. 2 input socket is loose some where. 3 loose contact near tuner or some print break. 4 at last & final its tuner might be defective. hope this will help.

Half Picture

I have seen this caused by 2 different problems. The vertical output IC could be bad but it is usually the CXA jungle IC that fails to cause this. Either way the set should be serviced by someone experienced in repairing Sony TV's.

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
