    Hi IrishDruid,
    This is not a LCD type tv. It is a WEGA CRT Sony. I don't think the dryer trick will work, but I will give it a try. I will try the reset.
    Thanks

Hello Papalion,

This is most likely due to 2 problems -Temperature or a bust capacitor,

1. There is a simple trick...just warm the back of the TV with a hair dryer for 5-7 mins after you have unplugged the TV. Look for the little areas of holes in the back panel of TV. Use these as your guide at where to use hairdryer., but don't hold the dryer too close(say 5-6inches away). (Make sure the dryer is on High heat). If the TV doesn't turn on after you have heated it up (like it tries to come on but then turns off) you need to unplug the TV again, this resets it. And repeat those steps till it works. Reseting the TV after it fails to turn on is the key. Also, just leave the TV on. Don't turn in off. Since it is LCD, it doesn't take much power...only a few bucks extra a month for your utility bill.

2. You can also try this..if you unplug the TV, and hold in the power button while plugging it back in, this will reset the TV, and sometimes it comes on.

3. If you want to go in for a long term solution, you can easily replace the whole power board (should be about $20 or so), or just change the faulty capacitors. You can make out which are faulty, because their caps will be swollen on top.
Check the specifications of the faulty capacitors, and get the replacements from your local electronics shop. If you are comfortable with this, you can use a pair of needle nose pliers to G-E-N-T-L-Y pull out the defunct capacitors. Once that is done, solder in the new capacitors carefully. If are unsure how to do this, try to get a friend who knows how to do this kinda stuff do it for you.

Hope that helps...Should you have any further questions, please feel free to post them here.

    Hello Papalion,

    Sorry, I seem to have typed the instructions for another problem I was solving simultaneously with yours, in here. (Hope I didn't type in your solution in the other post..hmmm..) Please pardon my error. But do go ahead and try the hairdryer and reset suggestions above :)

    From the symptoms you describe, it seems the high voltage flyback
    autotransformer has failed along with the horizontal amplifier (they
    are slaved to each other). This could have happened during the moving process. The sound comes from the flyback
    unit. I guess it must be a high pitched squeal, actually...

    Well, the only way to solve this is to get a technician take a look at the set, I'm afraid. Repairs could cost upto $100 or more, depending upon the number of components that need to be replaced,

    Since the set is new, it may be worth getting
    fixed up. If you decide to do so, call around, as shops have different
    rates and different expertise. Many shops are hurting for work because
    so many of the smaller sets are never repaired anymore; they are just
    thrown out and replaced since the cost of a new set is sometimes as low
    as the repair expense.



    Hope that helps...Should you have any further questions,
    please feel free to post them here.



    Cheers,
    IrishDruid

Hi there. Is there any chance that the set may have had a rough ride if it has been moved?

    Sometimes, if there has been a rapid downwards deceleration, a PCB may crack about some of the larger components. You can inspect the PCB's for fractures, and then repair them. It may also be poor soldering that has failed from the move. I would be checking for these things first.
    Powering down the set fully may have also allowed the power supply to cool, weak capacitors often go out of spec when they cool, this preventing may have prevented a section of the power supply from firing up properly again. If you care unsure, it may be time for a sony tech to take a look at it for you. REMEMBER there are very dangerous voltages inside a TV that can KILL. Be sure to work SAFE when dealing with electricity. DISCONNECT THE POWER BEFORE YOU DO ANYTHING.

    regards

My Sony Trinitron standyby/timer light keeps flashing,No picture or sound.Tried to hard reset it but wont work still its a kv35s42


Blinking of standby light to Sony TVs are fault indications. We can get an idea about the faulty circuit board, from the number of blinks occur at one time. Count this number. Make it sure by switch OFF and ON the TV at least three times. Visit this site named 'Electro-help". Blinking codes to Sony TVs are described in detail there. Pull up older posts. Check this link and select the site named above.

My picture would go out after several minutes but I still had sound. I took the rear cover off and blew all the dust off with compresed air.I did this for a few times over several days nothing happened.I also took off the rear circuit board that attaches to the tube with a round pin socket and blew that with compressed air and put it back on. The TV has now worked for two days without the picture going out. It worked!!!!!!!!!!!!!! My TV is 9 years old.

Flashing Standby/Stero light and No picture.


How good is your picture when it did come ? Is it as good as it once was ? Or is it alittle washed out. If it is washed out the picture tube is weak . Sometimes turning up the screen control alittle would solve problem but if you turn it up too much you would have faint white line running diagonally. Now if you think the picture was good before you this problem video circuit would be your suspect . Jungle IC or something in the RGB circuits . Good luck
