2000 sony kp53s75 tv wont turn on - was working great - no blinking light


This is a failure of the main power supply unit which is the Switch mode power supply- SMPS. You need to remove back panel and check the power supply for possible short in the chopper driver.

Hello, I have a 53-inch Panasonic PT-53WX42F TV, and it refuses to turn on. No picture, no sound. All it does is the tiny red power light blinks 3 times repeatedly. Can I fix this myself? What parts do I...


Thats a convergence failure when the led blinks 3 times. Your model uses the PT47WX42 convergence repair kit available from www.tvrepairworld.com the kit contains the parts and the CD with instructions for the repair.

2002 Sony KP53s75 is it worth repair?


Ok, 5 times is an akb problem, and without red, this tells me one of three things are most likley wrong either the red tube is too weak to produce return current to the akb circuit, or you have a bad driver on the crt board or you have a defective focus block. There are several diagnostics that need to be done to determine which one is the cause, if you are un familure with electronic repair it could be a little hazardus to do, so i don;t recommend it unless you are aware of the issues. If you swap the neck modules with the blue tube, and the set looses blue then it is not the tube. and might be worth repairing. but again if you don't have experience it may not be a good idea for you to try this yourself.

MY problem with Sony KP-53S35 53 in. Rear Projection Television. When the TV powers on, the red light blinks until the picture comes on, then the red light blinks go off. I had to wait more than 5 minutes...


the number of flashes of the red indicator lamp points to the possible cause of the delay of the raster or picture, but usually it's an indicator of an emission unbalance between crt(picture tube) guns. the picture will take longer to show up as the emission on either of the picture tubes goes down.

Ihave a sony KP53S75 TV there was apower surge and now there is no picture. The red light blinks 4 times can anyone tell me about this?


Hi, if this TV was hit by the surge and it was protected by a surge protector, please follow this reset procedure.

The STANDBY light will flash if an issue is detected within the television. This can sometimes be resolved by simply following the steps below to reset the television.
  1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
  2. Unplug the television power cord from the electrical outlet.
  3. Let the television remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
  5. Turn on the television.

If the problem is still there and the light is still blinking 4 times, this means that the surge has destroyed the Vertical deflection component. in this case, it will have to be replaced.

please rate and have a great day.

Rear Projection TV Sony KPFS 53 M31 :Red screen, 6 times blinking


Hi and welcome to FixYa,

Appreciate the direct "Ask Me".

For any TV model with a CRT or 3 tubes and your description of "red is getting too bright" indicates that the controller transistor or power pack IC for that gun/CRT/tube has shorted. Another possible indicator would be fine diagonal white lines and an overly high contrast.

Often this controller transistor or power pack IC would be heatsinked and located at a squarish PCB (printed circuit board) right at the very small end of the CRT/tube. Corrective action would require replacement.

If the "plastic box with 6 poties" you described would look like the image below, then that would be the Focus/Screen Adjustment for the three tubes.

Unfortunately I do not have a schematic or a service manual hence I could not be more specific. Should you be interested, a service manual is available here.

Good luck and Thank you for using FixYa. Happy Holidays.

Vertical deflection has stopped so IC509 ( vertical out) is defective or the vertical pulse buffer Q1505 is defective. That what cause the ledd to blink 4 times.
