    ok. now disconnect the collector of the horizontal out transistor.

    now try turning it on and check to see if the voltage remains.



    if so you have a crook flyback tranny.



    also before changing the tranny remove the vertical ic and attempt to start it.



    if it does start , it will come on with a line across the middle and normal sound.

7 blinks means High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.

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.

Won't turn on


Although the other response is in much better technical lingo, it sounds to me like the television had a high voltage arc which I have seen on quite a few of the sony big screens lately. Usually, it causes a part on the circuit board, (one of many that were listed on prev. solver's list) to fail. This causes a delimma for the repairman, because when they find the bad part and replace it, sometimes it will pop again causing repeat failure of boards and/or parts on the board. Sony is known for having bad tubes on their projection sets, and it can be a difficult repair even for a trained tech. I suggest calling a sony service center in your area, and get an accurate estimate before deciding if replacing the set is the best idea. Hope this is helpful input, Russmann.

Tv Powers up and immediately back off


This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. Shutdown at power with self diagnosis error 2-2. Check for open fuses F9A04 and F9A05 part # 283P144080 on the +24 and -24 volt lines. If the fuses are open the convergence output circuit would be suspect. 2. Shutdown at power with self diagnosis error 2-1. At power on check for 12-volts DC at connector KH pin 8, if missing check IC9C51 part # 270P990010 and L9C52 part # 441D009020 on the Signal PCB
