KP-41S4U TV (dead) stand by pulses a few times when the tv is switched on then stops and then after a short while begins to constantly pulse again.But TV is still dead.?

Time 2 buy another TV sorry!!!

Here are the fault codes for your tv and what components are affected:

• 0 times, Diagnosis: Power does not turn on. Possible causes include: Power cord is not plugged in, Fuse is burned out (F6001) (G board). Symptoms of the problem: Power does not come on, No power is supplied to the unit, AC power supply is faulty.
• 2 times, Diagnosis: B overcurrent (OCP). Possible causes: H. OUT (Q8024) is shorted. (D board), +B PWM (Q8035, 8038) is shorted. (D board) Symptoms of the problem: Power does not come on, Load on power line is shorted.
• 3 times, Diagnosis: +B overvoltage (OVP). Possible causes: IC501 is faulty (G board), IC5002 is faulty (G board). Symptoms of the problem: TV has entered standby mode.
• 4 times, Diagnosis: Vertical deflection stopped. Possible causes: +- 15V is not supplied. (D board), IC8003 is faulty. (A board) Symptoms of the problem: TV has entered standby state after horizontal raster, Vertical deflection pulse is stopped, Power line is shorted or power supply is stopped.
• 5 times, Diagnosis: White balance failure (Not balanced) Possible causes: Video out (IC7101, 7201, 7301) is faulty (CR, CG, CB board), CRT drive (IC309) is faulty (A board), G2 is improperly adjusted. Symptoms of the problem: No raster is generated, CRT cathode current detection reference pulse output is small.
• 6 times, Diagnosis: LOW B OCP/OVP (Overcurrent/over voltage). Possible causes: +5 line is overloaded. (A, B boards), +5 line is shorted. (A, B boards). Symptoms of the problem: No picture.
• 7 times, Diagnosis: Horizontal deflection stopped. Possible cause: Q8035, 8038 is shorted. (D board)
• 8 times, Diagnosis: High voltage error. Possible cause: T8005 is faulty. (D board)
• 9 times, Diagnosis: Audio error. Possible causes: +- 19V line is shorted. (A, B boards), IC708 is faulty. (A board), PS701 or PS702 is opened. (A board). Symptoms of the problem: No sound

I have seen the tube divider pack cause this too, Take the front speaker grill off remove the 4 screws and the panel comes off. There is a pack with 2 red 2 green and 2 blue adjustments, Try turning the BOTTOM red one down 1/32 a turn and see if the symptoms change

If the TV turn itself off then perform the following steps:

(i) Check if the Sleep timer is activated.

(ii) Check if the Parental Guide prohibits viewing during that time and/or limits amount of viewing time per day.

(iii) Check the batteries on your remote, low battery power may cause random signals from the remote.

(iv) Disconnect all the cables from the TV then reconnect them after a few hours.

(v) Ensure the power cord from the TV is directly connected to a functional wall outlet.

(vi) You may also try resetting the TV to the original factory settings by pressing the Reset button on the remote control supplied with the TV when in Menu.

The following is the information indicated by the blinking patter of the standby/timer lamp on the TV:

2 times : Power does not come on.
Load on power line shorted.

3 times : The TV has entered standby mode.

4 times : Has entered standby state after
horizontal raster.
Vertical deflection pulse is
stopped.
Power line is shorted, or
power supply is stopped.

5 times: No raster is generated.
CRT Cathode current detection
reference pulse output is small.

6 times: No picture

9 times : No sound

Furthermore, the TV is equipped with a self-diagnosis function that you can use to determine whether the issue is related to any hardware malfunctioning. Perform the step given below to run self diagnosis:

Quickly press the remote command button in the following order from the standby state.

Display -------> Channel 5 ---------> Volume -(minus) --------> Power ON.

If the Self Diagnosis display numeral "1" for any parameters then a fault has been detected and service will be required.



wish u good luck!!!!!!!!!!

Did you replace these Items?
IC1509(V out) i
Q1505(V Pulse Buffer)

Hi,
4 times flash of standby light shows that TV has problem in Vertical Deflection area and possible causes are IC1509(V out) is broken and / or Q1505(V Pulse Buffer) is broken.
Please check / test above said IF you have experience of TV repair.

Diagnosis: Vertical deflection stopped. Possible causes: +- 15V is not supplied. (D board), IC8003 is faulty. (A board) Symptoms of the problem: TV has entered standby state after horizontal raster, Vertical deflection pulse is stopped, Power line is shorted or power supply is stopped.

Hello Folks,
Thanks for getting back to me. Sorry, but my solution was to sell the TV. Am moving on to a canal boat and am getting rid of all sorts of stuff. Was going to repair TV before selling. I've given the buyer your Website details so you will be hearing from him.
Best regards,
Joe Killman

PS By the way, am living in France. Does that make any difference?

Given the vintage of set it might be hard to even get parts for it. And being a Sony, it is traditionally very expensive to repair and not really cost effective. Best bet is to give set a decent burial and shop for a new set.
