Sony KV-32FS120 I saw a prvious post for the same symptoms I am having. Dead set led blinks 9 times. The solution was to replace a couple of diodes on the "G" board. My set does not have a "G" board and I have the Sams photofact for this set. The diode numbers in the previous solution do not exist in this set. Any ideas?

I have taken the back off my TV. I pulled out the board. Can I perform the solders with the board at an angle. I really don't want to pull off the leads. As you can tell I haven't done this before but I always like trying.
Anonymous Apr 27, 2008

I cant seem to find these parts in the circuit board also is it on the circuit board that has a A or do I have to pull out the whole circuit board with all the wires also I tried and some of the wires won't come out does anyone have any pics?

Our 3+ year old Sony Wega ran into the same problem. My wife searched and found this wonderful and helpful web site. Followed these same instructions and resoldered these 7 components. The TV works again. Great web site. Thanks!
Suggestion to my biggest problem... carefully lay the TV screen side down to remove the back. Remember to remove the 7 screws around the connector section. Then, to remove the A-board, you need to reach down on the left side of the board and press down on a clip that holds the board in place. When the clip is held down you can easily slide the board out. You may also need to remove a few short wires/connections to be able to pull the board out completely out of the chassis. I did not remove all of the wires. I simply placed a towel on the tube and laid the board down on the towel to work on it. Good luck.

I followed your directions on this one and it fixed it--- on the "a" board (main board on the bottom of the set)-re-soldered d647,q605,c690,d645,d620,q691,q611..... a friend reminded me to hit the area with some contact cleaner to clean the flux off also but cheers to you!!! thanks !! btw---- this was on a wega kv-32fs320 !!!

This is correct the TV does not have a G board and the statement that resoldering the parts is misleading. I fixed my daughters by resoldering the following: D647 Q605 C690 D645 D620 R691 Q691 I tested all the parts in the circuit they tested good. I am an Electrical/Electronic Engineer this fix will do you well. Locate the Q605 located on the main boar and all the above parts listed. Or just carefully heat each of the pads in the area and add a small amount of solder. Make sure they are shinny dull is a problem joint. Don't put too much heat on the pad it will lift. Use a 15 to 30 watt grounded soldering iron. (has a ground on the ac plug) Fix it and enjoy saving yourself a large fee. PS do not mess with the small surface mount parts, you will be asking for more problems. If this don't work relist and I will give you voltages to check....

use a very thin solder, not some big old chunk of wire. I use solder that is about the size of 22 gauge wire and remember to use only rosin core solder never acid core.

My Sony Trintron's LED Light blinks 9 times when I try to turn on the set

If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 (negative). If you wish to get more details about the blinking codes to Sony brand TVs, check this link. Pull up older posts there.

Sony KV-32FS120 blinks 4 times

good day.
Have you tried first resoldering the terminals in the circuitry?
Also, try to check for the ABL supply near the flyback. Watch out for the small voltage zener diodes.

response is highly appreciated.

SYMPTOMS
Dead or Shutdown symptoms.

Found Q601 & Q602 shorted, R615 open, and IC600 on the A Board were the cause of the symptom.

2. Dead.
Found D614, Zener diode, on B+ line was shorted.

3. Set shutdown and the standby LED blinks 3 then 5 times.
Found 200v line was low. Disconnected CN706 on the C Board and found 200v now
present on CN706/pin 7.
Found: IC702 (C board) shorted the 200 volt line.
HQ Comments: C541 on the A Board could become defective if the 200v line is shorted since
the polarity on the capacitor will become reversed. R553 fuse resistor could also be opened
on the A Board.

4. Error code of 4 blinks .
Dead set press power button you hear the relay and you see red led flash 3 times and stops? Has no HV or other action. Tech removed the back as no 200 volt supply, did unplug CN706 and now has 200volts. Tech did remove the IC702 and same it comes up so needs this IC.

5. Dead. 5 blinks then 3 blinks. Found shorted Damper diode D504. Q502 has a built in damper, as well.

6. The TV does not turn On and the LED flashers 9 times.
Found one side of R610 open on the Base of Q690 on the A board.

7. Dead, 9 flashes, Q606
Would not start when cold, has stand by 5 but relay never energize.
No response from front panel or remote controls.
9 blinks is not in service manual.

Found Q606 (Zero Det.), on the A Board, had no soldered on the collector
of the transistor causing an intermittent connection.
Soldered the collector of Q606 and set returned to operation.
HQ Comments: Also refer to E30968554.

8. Dead. 5 blinks or 3 blinks
Found on the A Board D611 in the Power Supply open, and Hor. Output Q502 shorted.

9. Found Power Supply components D611 shorted causing Q600, Q601, and R615
to fail on the A Board.

10. No picture or sound. Standby flashes.
Found Q512 (Pin Out) shorted. on the A Board.

11. Dead. No sound or picture.
Found the FBT and Q502 were shorted, and R615 open on the A Board.

12. Dead
No power, Stand by light flashes 4 times.
Found T604 and IC601, replaced.
Found D611 on the A Board was the cause of the symptom.

13. Dead.
Found D534 shorted on the A Board.

14. Shutdown 4 Blinks.
Replacing R595, OCP Latch Q532 on the A Board, fixed the set.
PN 1-247-891-00, 330K 1/4 watt.
