Question about Sony KP-57WS520 57" Rear Projection HDTV-Ready Television

2 Answers

No Power-blinks 9 times

I've seen many of the same solutions to this problem, but do I dare take out the G board myself? Will it screw anything else up. You can't get a new G board anymore. Where do you get the diodes and how do you replace them yourself.

Diodes can be repaired through fault finding. You will need to locate test points on the board to identify the faulty diode if indeed it is this.

Led with number 9 displayed is flashing


LED 9 flashing can mean many things. Here is the list of "flashing codes" for the vostro 1510.

Keep in mind a flashing led is going to blink 3 times. for example,

number one would look like this:

On (solid lit). Blink, blink,blink (paused off) blink, blink, blink... (paused off), (then repeat)


1. ON-FLASH-FLASH = No Ram or ram not seen
2. ON-FLASH-ON = Ram has a problem
3. FLASH-FLASH-FLASH = Motherboard failure (replace board)
4. FLASH-ON-ON = CPU Fault/failure
5. FLASH-ON-FLASH = LCD detect failure/fault
6. ON-ON-FLASH = MINI pci card (controller) failure/fault
7. FLASH-FLASH-OFF = Keyboard fault/failure
8. FLASH-OFF-FLASH = USB FAILURE
9. FLASH-FLASH-ON = Video BIOS or BIOS issue
10. ON-FLASH-FLASH = Modem issue

Depending on the blinking code, you might just need to re-seat or replace your RAM or your CPU. But then again, you could have a more severe motherboard issue.

No power


Check the ribbon cable connections between the boards to insure they are correctly seated as a 19 code usually means
Chassis detection, which means its not detecting a valid chassis usally the ribbon connections are the cause of that.

4 blinking lights


I fixed it myself!
I bit the bullet and ordered a replacement Power Board for AUS$290 and swapped it out myself.
Only took ten minutes, most of that time was removing and replacing the 101 screws holding the back panel on!
Working fine again now.
I did sit the two boards side by side and noticed the new one had moved some of the micro components from the back of the board to the front plus some other small component changes.
If your handy with a screw driver and have some technical knowhow I recommend having a go at fixing it yourself as it wasn't hard and probably saved $200 in service charges (all this assuming you are out of warranty!)

Relay click and 9 blinking led.


Try the following steps:
1. Remove the power supply to X Main board, check VE. If you get normal VE then replace the X Main board. Otherwise to 2.
2. Remove the power supply to Y Main board, check VE. If you get VE then replace the Y Main board, otherwise to 3.
3. Replace the SMPS board & SMPS 200V board.

Good Luck
