Sony KP53XBR45 Hi, this tv lost video while watching it but still had sound. now when press power button the light flashes 7-times and will not power up. Please help, Thanks.


the IC's on the circuit board will have to be replaced. it is common. this controls the convergance which seems to be off. the stk's can also be bad causing no picture. Depending on what type you have. You can get a manual and a tester and test each cap to see which one is the faulty one.

Sony KP53XBR45 Customer was watching it and the picture just whent out but still had sound. Now when press power button the LED light flashes 7-times and won't turn on. Any suggestions? Thanks, Alltech...


Are you getting sound? If not, then your power supply is faulty. If you sound but no picture, then an IC or STK capacitors are faulty depending on what type of tv it is.

Sony Wega stanby light blinks 5 or 6 times


When a Sony TV flashes five times, that means that there is an AKB circuit fault.
Six blinks is also a fault related to video problems, and regards a fault concerning the digital board and the Jungle IC (the main CPU).

This means that there is something wrong with the video.
Try first unplugging power for few hours, if that does not work, call a technician, as several IC and components must be tested and eventually replaced.

Won't turn on


Flashing or blinkings diagnostic code meaning;

Ten blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board

Bad solder or loose, crack ,cold solder connections joint,you must reworks or resolder joint of the "D" board so it will works normal again.

Hopes it may help you;
