Sony kv-32fs120 blinks 9 times

you need to replace some parts
Q691 is an 2sa933 transistor
D647 in an 10erb20 rectifier

well you can get our service manual or thye eletronic schemetic for it. just google it for your model tc.. The circuit components are labeled and you there should be a name. but if you said you didnt see any then its proberally under the component, id guess in such a case you will need the service manual ir the schemetic. as far as i am aware you need to get it from the manufacture or some sites have pirated copies of it.. you can google it if you want or simply contact your manufacture..

Hi Baddragon,

 

I do not want to get in between you and Besee. however, since you are thinking of Throwing in the towel. I suggest you think of stepping back from component level repair on Circuit baords, and think about going to PC board level troubleshooting. This is easier, more expensive, and your more apt to succeed.  It is very tedious working with Surface mount components. Basically overly time consuming.

We can get the circuit boards you need from www.partstore.com. 

 Just get the part numbers from the Circuit boards you have been soldering on.   You may want the challenge of component level repair.  You did say your staying away from surface mount components, a new circuit board solves that problem.   I hope this helps you.

 

I had the same problem with Sony KV-32fs120 with 9 blinks. Replaced D645 and D647 on main board with 1.5A1KV diodes from Radio Shack which did the trick.

The problem with this model is the large parts due to poor wave soldering. Locate the transistor Q605. Using a small wattage soldering iron melt the solder and add a little solder to all the large parts in the area. Small wattage = 15 to 30 watt. Stay away from the surface mounts they are not the problem. I resoldered the following: D647
Q605 C690 D645 D620 R691 Q691
These parts are located on the main board, the one the power cord connects to. Carefully press the clip on the left side of the board (as you look at it from the rear of the tv) carefully pull the main board back and out of the rails. You will find the parts on the right side of the main board about 2 inches over 2 inches down.

Replace diodes D645, and D647 in standby power supply circuit.
Part# 6-500-567-01

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....

This model does not have a G board. I will post when I have this solved.

How many blinks does the timer light flash? On a Sony this is a troubleshooting device.
