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.

Please count the blinks and post that number. That is an internal diagnostic code that will indicate the problem circuit. From that I can give you probable repair parts and costs.

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.
