Question about Sony FD Trinitron WEGA KV-32HS420 32" TV

1 Answer

Sony KV-32HS420 won't come on.

MY Sony KV-32HS420 stand by timer blinks 7 times then pauses, and the TV won't come on for several days, and when we finally get it to come on then the timer blinks 5 times. I found out what the 7 blinks means (horizontal deflection stopped--- at least one IC on D board needs to be replaced). What does the 5 blink mean when it's on. I'm afraid to turn it of because it'll be a while before it comes on again. If it even does. I think this is a fairly common problem for this model.

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

I would look for a Vertical circuit failure. Most likely is the vertical output IC and or open resistor off the hv transformer. Definitely look for any loose solder connections around the Vertical output IC.
Hope this helps,

You have what is commonly known as a shutdown problem. It's an overload in one of the internal circuits. It needs to be looked at by a professional tv reapir person.

The 7 blinks on this model indicates that the horizontal section of the TV has stopped working. Horizontal Deflection Stopped

Occurs when either:

1) a +B overcurrent is detected (IC5007), or
2) overheating is detected (Thermistor TH5002).

I have the serrvice manual if you need it. Let me know where to send it to.

Have Sony KV-34HS420 with no picture or sound. Timer/Stand By light flashes 7 times with pause in between. What is the likely problem and cost to repair?


Hold hair dryer to back right side on high heat for a couple of seconds while you hit the power button several times. It only took 2 times for my set to power on. Good Luck!
