First check if the signal source is Ok - Antenna, cable, Cable connector.... One of them is at fault.

SOURCE: Sony Trinitron KV35V36 Glass Chip

fill in the spot with clear epoxy from radio shack. Place shipping tape over the epoxy and turn the screen up if possible to make the repair flat. Wipe off any excess epoxy as the tape is applied. The break refracts the light from the screen away from you and makes it appear dark. Remove the tape after the epoxy sets. Do not open the unit up. The aquadag can hold high voltage for up to a month. There should be no danger of breaking the crt itself if you're careful. Over time, recycling the power on and off may make any cracks propagate but if there are none now it should be ok.

Apex TV. It turns on. Have sound. Why no picture?

  1. Unplug the TV overnight and then plug it back in and SOMETIMES it could work and fix your issue.
  2. Unplug the TV and everything hooked to it, and then plugging it back in may clear the problem.
  3. Make sure that the TV is set to the correct input.
  4. If the TV screen still remains dark unplug your TV and push the power button for about one minute and then plug it back in. See if that resets your TV. If it still remains dark use a flashlight and angle it against the screen with the TV at a station where you can hear the sound See if you can make out shadows or shapes

My mitsubishi 65in tv has a lot of small white dots on the screen what causes this?

projection tvs can display white dots from the dust that is on the reflector mirror your lamp shines the picture on before it is reflected onto the front screen of your tv, one must be very careful when cleaning this, may be worth a service man doing it for you

The screan is too dark while I am watching tv

If a conventional picture tube type set it will have a high voltage transformer inside with a focus and "screen" control--in this case the screen needs to be adjusted up slightly.

Adjustment is inside the set so you have to have back off and be careful as high voltage is present when set is on (need it on to adjust the screen control just up a tiny bit).

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...

From YUBEUT...

Picture too dark

You didn't say if you are receiving an off air picture or cable or satellite. The reason the commercials look good is because the local station (or source) transmits them "in the clear", that is, without any enhancements to the video signal. Network programing or local newscasts are sent through a device which inserts a reference signal in what's called the "vertical interval". You may have seen this as a series of flashing dots or pulses at the very top of the picture. There's a lot of information packed into the VITS (Vertcal Interval Test Signal). One of the lines contains a reference pulse for video which is set at a certain level. Your TV sees that level and automatically adjusts its circuitry accordingly. What I suspect is that your set is out of calibration and is pushing down the video signal because it is not "seeing" the level properly. A video alignment should correct this and can be done by a good repair facility. Hope this helps.

The TV turns on and you can hear the sound but the picture is dark except for a thin line of blue dots in the center of the screen.

You have whats known in the biz as a cold solder connection on the vertical output IC or on the associated components. Not a job for the handi-man unless you know the issues with safty, and precautions to take with Hi voltage inside of tv sets. Shouldnrt cost much for the local shop to find your problem . Now on rare occations the poor connections are inside the IC and the IC has to be replaced. Good Luck
