Sony kv35s66: No picture, just sound and red blinking

We've had the Sony Trinitron kv35s66 for about 5 or 6 years; manufactured in 1999. Sometimes the picture goes out leaving the screen black, but there is sound. Usually, before going out, the screen picture starts having horizontal lines, the screen picture gets shorter and shorter (the width is fine), and then sometimes it goes to black. There is no red blinking light after it has been on for awhile. Sometimes it comes on just fine. Other times when we turn the tv on, the red light flashes over and over, the screen stays black but we have sound. We always have sound. Sometime the picture will just come on. It may be right away or sometimes it's 10 minutes or longer, or the picture won't come on at all. We have unplugged it from our APC battery backup/surge protector unit and plugged directly into an wall outlet. We have reset the power many times. We can't afford a new TV right now, so we are wondering if this is a quick fix, or will we need to toss this out.

    Sony KV-35s66-The set has always had sound, but a delay in picture when you turn it on.

    Recently, after about 40,000 hours of use, the delay has increased.

    Now, the delay is over a minute and a half long, with the standby/timer light at the bottom of the set flashing the entire time.

    Then the picture comes on, and the standby/timer light goes out, but the picture flashes on and off for about five minutes before locking on for the rest of the day. It appears to be resetting, because the channel display appears on screen each time the picture comes on.

    With this many hours on the set, and what appears to be a weak picture, I'm reluctant to put money into it. However, I guess it might be possible that whatever is causing the malfunction, might also be diminishing the clarity of the picture.

    Please Help!

    The sony Trinitron turned itself off and won't come back on. There is a red blinking light at the bottom near 'timer,standby'. We are hooked to cable and the cable is fine. Can anyone tell me how to get the tv back on?

The most common problem (I have fixed lots) is the Vertical amplifier has developed a loose connection. It probably just needs resoldering. As things expand it makes and looses connection you picture goes in and out. The vertical chip is a large black chip that gets hot, over time it degrades the solder until a connection is damaged. Most newer sets have a protection circuit that senses the lack of height, and shuts down the picture tube to save it. When the picture dropped to a line on older TVs and left that way too long it would burn a line into the face of the picture tube. You then had to have the picture tube replaced along with the vertical amp. it's kinda like a screensaver for your TV.

check the heater as your tv is ON, there must be a yellow light at the rear of the CRT tube. If the heater is ok then check the IC jungle side. resoldering the leads sometimes will solve. If not refer to your local Tech.

TV screen goes black but tv is on. But will stay on sometimes.


i have a 2000ish 32 inch trinitron Wega and i have had the EXACT same problems as you have, except mine was blacking out more and more frequently, but yes if u changes the channel or hit return onto the same channel you're watchin the picture wil come back, but not very long, about the longest it'll show a steady picture is 1/2 hr, but it's usualy going black within every 10-15 mins or so.

I took it to a Sony approved/recommened repair shop and aftet having a look i was told it would cost $200 cd including taxes to replace a 'vacuum tube' or something like that, i wish i could be more specific anout the part. I'm still considering whether or not to go through with the repair. I might just buy a working/used newer Tube Flascreen with HD for another couple hundred dollars. If there was a newer 2003+ 32 or 36" Sony that has a good track record I would love to hear suggestions. I don' trust flat panels, way too mny horror stories, and for every 1 i hear about there's probably 10-20 more.I'll give them another 5 years or so to get their acts together.

On the other had, if i do decide to get my 32" wega fixed i will post the results and the exact pt numbers of the pts used i the repair. Your problem is exactly the same as mine, to the letter. I'm a mechanic by trade, but i have a good feeling they're not going to give me correct pt # until i have payed them to fix it. Or else i'd order the part and install it myself.

Good Luck,
Aaron

Sony kv35s66: No picture, just sound and red blinking


This should be a quick fix. Try resoldering the vertical IC. This is a small flat IC attached to a heat sink with about 11 pins. It should be marked LA7837 or something similar. That should resolve the problem.

Keep us posted.

Sony Trinitron - Picture Disappears


Hi, IK circuit is engaging which basically means the picture tube is getting tired, the only "fix" is temporary (may get another year out of it). You have to increase the "screen control clockwise".
Remove back of set, follow large black or red wire attatched to picture tube down to the flyback transformer, mounted on flyback are two black controls, one is focus (leave it alone) the other is "screen", adjust it clockwise approx. 1/4 inch, remember that this is a high voltage circuit so use one hand in the set the other hand out of the set at all times,any questions ? e-mail me back, good luck, BMW Rider

Sony Trinitron experiences


The screen control inside the set may be on the highvoltage transformer or on the crt socket; either way if you can turn it up just a little clockwise and the picture comes up but doesn't look good you are likely to have a bad tube. Or try tapping lightly on the glass neck and watch the picture as you tap. If it reacts to the tap you have a bad tube. but the turning the screen control is the best test. Turn it the other way the picture goes off immediately. bad tube: too costly if it is available.

Sony Trinitron KV-32S40 32" TV problem


This is a simple and common problem. The solder joints on the vertical output IC have cracked loose. I actually did a housecall on the exact same set with the exact same symptoms this morning! A good tech will resolder the pins of the vertical output IC and all other major solder joints on the main board and the set will play fine.
