Question about Sony FD Trinitron WEGA KV-32FS120 32" TV

9 blinks on standby LED

I seen some posts on here about same problem.  So I have already re-soldered parts Q605, D647, Q605, C690, D645, R691, and Q691.  and for the first week everything was fine.  Then problem came back.  The whole back of this board is dull gray, so i decided to clean up some of these connections hopeing this would solve the problem again.  No luck with that.  I stayed away from all surface mounts (micro resistors and transistors) execpt in the power supply area (Q605).  Where should I start looking for voltages?  I have a multimeter in order to get voltages, resistences, and capaitors readings if needed.  I would prefer a responce by besee, seeing that i've been following his advice on this matter.  Or is it time to throw in the towel and get a TV repair tech?

    Around 8pm 10-13-07 I finally got the set to surn on by remote.  So any damage I thought might have happened, wasn't so.  Replacing that board I would think would be costly.  However, because I'm looking for a permanent fix, this might be an alternative.

Your problem is in power supply section in your tv.
if it is ok check for h/output section.
This problem may also be due to moisture content in the flyback transformer surrounding area. Due to this moisture content screen control voltage is changed. Without getting a exact voltage the indicator will not stop. 5 times blinking is only for screen malfunction. Make one general service by cleaning the deflection area and adjusting screen control the problem is solved.

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.

Stays on standby mode


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..

Sonny tv problem


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.

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....

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