Television when i turn on the tv the screen only works through the center of the tv about two or three inches tall, if i wait a few minutes and tap the tv at the bottom near the buttons with minimal force the screen will spread out and stay sometimes other times the tv will power itself off and the back on with the same screen problem. what can i do to fix this?

This is a failure in the vertical amp section. One way to troubleshoot it is to get a can of freeze spray and use it on the suspect components. The other way is to inspect all the solder joints on the amp. Last would be to check voltages on the board. Since it does change with run time, it is being affected by heat.

The set literally has a 3 strikes and you are out where it will try three times and go to shutdown.

The common issues this set has are bad solder connections under and around the high voltage transformer and also in some cases the High voltage splitter block (located way up front behind lower grill below screen unit and behind a removable inspection plate).

The transformer rarely fails but can--photo of what is general appearance of this type of part is attached.

Thats a common symptom which is usually caused by the Small signal board. You can get a replacement small signal board from www.tvrepairworld.com

hello my friend you have some loose connections on the digital board.this board is located right in the top center of the tv.if you do not have repair skills call the repairman he should not charge you too much for this job. good luck

your closed caption feature is turn on and in the text mode. either turn off the closed captions or change it from text to cc1

Needs convergence amps replaced. Sometimes resistors burn and need to be replaced. This repair requires soldering/desoldering equip. and a trained eye, but usually can be done for 175.00-325.00 at a reputable service center. Good luck, Russmann.

sir do a power reseet ,turn off the tv then unplug it from the electrical source then wait for 1 minute then plug it in and turn it on if it doesn't work call sony customer serveice at 1800 222 7669

can u give a lil more details on the problem

CTPATS-THATBOX IS MOST LIKELY DUE TO THE TV HAVING THE CLOSED CAPTION TEXT FUNCTION ON,SIMPLY GO INTO YOUR MENU AND TURN THE CLOSED CAPTIONS OFF. JOE TV

Hi,

 

Not familiar with your actual model.

But a comon problem with older Tosh sets is the 2.2uf electrolytic caps from memory they are usually red there is 1 next to frame Ic & the second is near Psu.

Allso check frame o/p IC for dry solder joints this is easy to test for.

Tap the tv while it is on if the the frame suddenly pop to full size picture you know its dry joints so resolder frame IC.
