Sony Projection TV KP-43HT20

Our TV has started going out and shows a "No Signal" message. We have noticed that it goes out most once it's first been turned on in the morning or in the evening (after being off for a long period of times). It stays out for a couple of seconds to 20 minutes. A lot of times, we can turn it off and then on again and it will work. Once the TV is "warmed up", it seems to be fine. The picture is always fine when it's on. It will play DVD's with no problems at all.

    We called a tech - they suggested a problem with our cable input box in the TV??? I guess I would have liked a few more details to this solution, but really appreciate your willingness to respond and help!

    Bought it from a reliable friend and she said it never gave her any trouble. Worked great for a few days, then cut to the No Signal. Nothing wrong with the cable box. Tried every connection sequence in the manuel. No cable box. Cable box only. Box and dvd. Same results. Leave tv off for a bit, cable works for a few minutes, then No Signal. I want to throw this thing off the roof, but it's too heavy, so please help me get it working again.

    I have recently experienced a similar problem. For the last week, after my tv warms up, lines appear on the screen with a crackling popping sound and you are unable to really see what is going on. After a few mintues, it will be fine. It will do this on and off the whole time the tv is on. Sometimes if you turn the tv off and turn it back on it helps for a bit. Last night it did go to NO SIGNAL. I checked all my cables, taking them out and retightening them with no luck. Still this morning NO SIGNAL. I did watch a dvd two days ago, but did not try that this morning.



    Please help, the kids are losing it without the tb....

Main screen showing "no signal"

KP-43HT20 has 2 tuners, one is main (TU2) and 2nd is called sub tuner (TU1). Both tuners are mounted on A board located on right side of TV.
In my opinion, main tuner (TU2) is not working and causing No Signal message.
Let me know if you want to repair tv by yourself.to provide you more technical info.

Sony KP-43HT20 Projection TV

5 times blinks is error code for No Good White Balance and you said that picture is very green.
As you know TV is approx 7 years old so it needs RGB gain adjustments.
If you are TV tech person or know about TV repair, let me know to guide you further. Or contact local TV repair shop to fix it.
