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

  • Bob61E May 30, 2008

    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.

The price sounds very reasonable, the fix can be done by someone who knows how to solder. It is fairly simple but should only be attempted by someone who can solder and knows what is dangerous such as the capacitors. The tv should be unplugged overnight to give time to discharge and to fix it, simply cut off the old soldered connections and solder the new pieces back on.

let me know if you have any further questions.

If you don't know how to solder, then having the repairman do it wouldn't be a bad idea, but you could also see what someone else may charge you.

good luck

Model # P529265 T.V. will not turn on. What is the problem?

Hello jana_john219,

Welcome, and thank you for using FixYa!

Your issue is with one of three things. All of which will have to be examined by a TV Repairman, if you want to spend the money fixing this set.

1. 5V high/low power transistors are dead (1 or both)
2. Flyback Transformer is dead
3. Cold soldier joints around the three parts I just listed.

Most repairs will cost close too or more than a replacement TV. Your choice.

Have a great day!

Tv shut off while watching

We have the same trouble! It is the power transformer. These models had faulty ones. Can you believe that this is the 2nd time we have had this problem? And our Beautiful RCA XBOX Entertainment Series TV's that is only 6 years old and there cousins all have these problems!!!! Our repairman (and good friend) told us that it would cost about $250 to fix. Of course he didn't recommend us doing this because the TV TUBES in these series are also very weak. He says that these Large Screen RCA TV's do not make it much past 5 to 7 years. So if you spend the money to have it fixed you will most likely be wasting your time and your money! Sure it will work for another year, but that is about all!
It is far better do what we are doing and go out and buy a new TV. Our Repairman Friend spend a lot of time researching new Flat Screen TV's for good quality and longevity. He states that we all should look at buying a good solid brand like Panasonic if you are going with a 32 inch TV or smaller. A Sharp if you are going larger then 32 inch. Far Better Quality on these TV's and a lot longer life! He states that the other cheap ones that we see out there today already are having a lot of problems! You get what you pay for!
These cheaper so-called bargains will have lots more problems in the months ahead and most will more then likely stop working all together in 2 to 4 years. So buyers beware of these great TV prices on these cheaper models! PLEASE do your homework and please listen to us and our repairman and you will not end up screwed like we were! Now we are stuck with an old RCA clunker which warranty expired after the first fix which was not done correctly! They came out and put a little solder and adjusted the Transformer instead of replacing. It was just enough to last another 6 months for the warranty to expire! Shame on you RCA! We then went out and bought one of these cheaper models and found that the quality is terrible! It already has problems and we are fighting to get them to honor the Warranty! Did I mention buyer beware? Something that looks and sounds too good to be true usually always is! Sorry for the long response! I just hope thise helps others!

No picture or sound just three low beeps

Hi guzzman2,

I have the same exact TV as you and it has the same problem. I took the whole tv apart and checked the obvious things i.e. fuse, loose board, etc. etc. Bottom line - it looks like the flyback transformer needs replacment This is what provides the picture tube with power/voltage, etc. The part itself is ~200.00 and the labor will be about $150.00 - $200.00. Thats what you would pay if its only the transformer. Usually when the transformer goes, it takes other components along with it. I am bringing my set to the recycling center since It's not worth fixing. Went to Costco and bought a 42" LCD tv for less than 900.00. Instead of spending upwards of $300.00-400.00 to fix a 13 yr old standard tv, go for the gusto and upgrade to High Defination TV with the appropriate Cable company box and you'll never regret it!!!!
What a wake up call to watch TV now!!!!!!!!! Good luck to you...

Dark picture on toshiba tv 32af44

Sound like the back light has gone, its what gives the picture brightness. Sounds like a technician job. Sorry........

Apr 10, 2008 | Toshiba 32AF44 32" TV

1 Answer


Can you do this? Take the back off and look next to the transformer (has large red wires coming out) and have someone turn on the set and if you see a glowing device next to the transformer then the High voltage splitter is bad and if no glow then transformer is bad. This is for information purposes only. Changing these parts is for the trained only and could cost on average $300 parts and labor depending on the repairman and location you are living.

Toshiba 35A44 - Dark picture on all channels and DVD's

for this brightness problem actually came out from flyback, before you spend and waste your money, try to adjust at back of your tv first. But if you aren't an expert, better ask technician to do because that transformer supply a very high voltage....there's two adjustment point at flyback transformer, one point for focus and the other one for brightness! try first...
