Good Day, cheriejesse;

There are many things in this Model that can cause this problem. So I would recommend that you call an Authorized Service Dealer to come to your home & give an estimate.
The most common problem though is the IHVT.
Good Luck, big IRISH.

SONY KP-53S75 tv problem


the four times is a code for what part of your tv is having issues. A Qualified Sony Service Shop should be able to give you an idea and or cost of what the repair is. 'Call around'
1) My thoughts is that there is either an HOT, 'High Output Transistor' that has gone out or maybe even a flyback that sends the High voltage to your 3 crts.

On light blinks 4 times psuses and repeats itself.


Hi


Thanks for using FixYa. Unplug the TV and leave it unplugged for more than 4 hours to allow the capacitors to fully discharge and reset your fault detection circuitry.
Plug it back in and turn it on. Also open the back cover and clean all the dust with vacuum cleaner. If still the issue persists then it means that the high voltage generation circuits are bad or there is no vertical deflection (V STOP) and the screen goes to a single horizontal line then the video signal muted. Check IC 1509, transistor Q1505 with a multimeter.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

On My sony kp 53s75 tv the picture does not fill the whole screen on the HD channels


it is most likely normal--first generation HD sets were 4X3 which means picture is either small left and right or top and bottom; sets which have 16X9 offer full screen HD

Good Day,

Dead set , more than likely the TECH that came out is correct.It is common for this unit.
It seems though, that you questioning the repair cost. To me that repair cost is very, very, very good.
Technician's are experience people in their field, like a DOCTOR, it is not the time but the schooling and experience that you are paying for.

Good Night, big IRISH.

Good Day, Martin Ping;

Picture won't merge? It sounds like your TV has had a failure in the CONVERGENCE CIRCUIT by replacing those IC's should correct your TV's problem.

Good Night and Luck, big IRISH.

Good Day, menudude;

The Sony your friend gave you is a 2000 Model and cost about $2,000.00 and you don't want to spend $400.00 to get it repaired? GET THE TV REPAIRED FOR THE MONEY.

Good night & Luck, big IRISH.
