Question about Sony KV-32FS12 32" TV

1 Answer

TV won't turn on

I picked up this TV from someone who didn't want to spend the $$$ to fix it. A repairman told him it was likely a bad step-up transformer. After the initial click when the TV is turned on, I hear 4 or 5 more clicks and then nothing. Sounds like something is repeatedly trying to start up but can't get going. If I can get help troubleshooting this & I'd like to repair it myself. Thanks so much! Bob

    Welcomejee - Thanks for responding so quickly to my post. I'm a definite do-it-yourselfer and believe I'm knowledgeable enough to avoid frying myself. That being said, if you recommend that only a true TV tech work on such a set, I'll probably get rid of the TV.

    Anyhow, in response to your question, the stand-by light blinks in the following pattern when the set is turned on (an "L" means a long blink, "S" means a short blink & a space means a pause between sets of blinks):

    LSS LSL SL SL (SL continues to repeat)

    Any suggestions or further questions you have based on the above are most appreciated! Bob

    Thanks again Welcomejee! I have a multimeter for testing purposes & I should be able to locate the components you've referenced. Can you tell me how to test the components to see if they're bad?


  • Bob61E May 31, 2008

    Welcomejee - Thanks for the detailed instructions. I tested the Hor. Output transistor Q502 on the A board & found no resistance in the base-collector contact. There was some resistance in the base-emmiter contact. Sounds like I should replace this transistor? Would you recommend any other testing or parts replacements while I'm making this repair? I can't thank you enough for your suggestions.


  • Bob61E May 31, 2008

    Welcomejee - One more thing. I tested the Q502 transistor while it was still soldered in the circuit board. Does this transistor need to be removed for proper testing? Thanks, Bob

  • Bob61E Jun 02, 2008

    Welcomejee - Thanks for the further guidance. I'll take the transistor off of the board & re-test it. Unfortunately, I'll be unable to do that this week. I'll post my findings in a week or so & if you're still able to help that would be most appreciated. Take care,


  • Bob61E Jun 16, 2008

    Welcomejee - I hope you're well. I finally got back in town & removed the Q502 HOT for testing. I found no resistance between the Base-Collector contacts. I found some resistance between the Base-Emitter contacts. Based on your previous guidance, sounds like the HOT needs replacing, but should I test anything else? Also, the HOT is labeled "D2580" but when I looked for parts online, I could only find a transistor number "2D2580" are these compatible, or can you direct me to a good website for buying parts?

    Thanks so mcuh for your help!

    HI! I have same identical problem.After the initial click when the TV is turned on, I hear 4 or 5 more clicks and then nothing. Sounds like something(relley) is repeatedly trying to start up but can't get going.,the only different it is that ,will blink 4 times-pause-4 times-pause and so on. If I can get help troubleshooting this & I'd like to repair it myself. Thanks so much!

    Alright, 2 times blinks shows that its "Horizontal Output Transistor Q502" on A board or "IC702" on CA board could be defective.

    Please check n let me know out come.

    well, you can test Transistor by multimeter but cant test IC. Transistor has 3 pins named Base-Collector and Emmiter. Please select Resistance Measure X1 range at multimeter and touch both black-red probes to confirm needel movement. now put black probe on Base terminal of transistor and touch red probe to Collector. watch the screen og multi meter, it will show you some resistance, means good. now touch red probe to Emmiter pin of transistor and confirm same resistance value as it was on Collector. Transistor is in good condition. This is test procedure for general purpose NPN transistor. Now come to H-Out transistor Q502 in your tv. its base-collector contact will show resistance but base-emmiter will show very less resistance. hope this info will be useful.

    Hi Bob,

    Transistor should be out of board to test properly. If its found short, replace it pls.

As far as the TV is now at any service center, it will be wiser to make it repaired there. Otherwise, you might have to spend more; sometimes will get it back in irreparable condition. I assume that, you will understand my words. Gopakumar Gopalan Google

The projector is out of alignment. Special tools are needed, so you might have to take to a repairman. I have that same tv, it did that same thing last year during the superbowl, I called a repairman and he fixed it in less than an hour.

My TV will not turn on, I then unplug it for 20 minutes and it comes on, then suddenly turns off again, is there a way to fix this?

Hi, Yes, there is a way to fix. You need to take the back of the TV off.
Then find the power board and check for bad Capacitors on it.
If you can't do it. Take it to someone who can repair it. (Repairman)

The tv usually turns on but all of a sudden it won't. When it does turn on it makes a loud noise like a boat. Someone told me its the fan but I'm not 100% sure though. The noise stays on until the tv

Sounds like the motherboard on the TV has failed. Would recommend replacing the TV or taking it to a TV repair shop which may cost more than just replacing it.

GMC 2000 sierra pick up 1500 sounds like it wants to start but won't turn over. Battery sounds good so I guess battery and alternator are ok. For several years fuel gauge doesn't work and...

It sure could be. But, "won't turn over" you do mean it cranks at normal speed but won't start?
A simple test of the fuel pump is to stand by tank and listen as someone turns key to on. When first turned to on, your pump will activate for 2 or 3 seconds, pressurizing the fuel system, and then shut off if the engine computer doesn't get a cranking signal. Do you hear it come on? If not, then something's not turning your pump on. If you can hear it buzz on briefly, then maybe it's your filter. Another test: Spray a little starting fluid into your intake manifold (remove the big hose going into intake manifold) while someone tries starting it.If it doesn't fire and try to stay running, then it's probably an ignition problem. But if it does fire off, then you know it's a fuel problem-likely your pump or filter. good luck.

Sony FD Trinitron Model: KV-32HS420. Turns on for 3 sec.

Its a problem with the capacitors on the main board. If you open it up you will notice that 1 or maybe two of them have puffed at the tops. Sony will fix this for you for about 200 buxs or if your able to, pull the capacitors yourself and take them to radioshack. You might spend 15 bux tops.
