Re: slow to come on, picture flashes black, 32" SONY tv

Blankenship, the "IK circuit" is blanking your screen, only "fix" is temporary, remove back of tv, and on rear right side (facing into the back of the set) you can see 2 philips type plastic screws mounted on the flyback transformer, one is focus the other is screen, do not adjust focus , turn screen control clockwise slowly until you get white retrace lines on screen, then turn counterclockwise until retrace lines disappear, this increases drive from tube to IK circuit, will last anywhere from 6 months to 18 months and then it`s replacement time, questions? e-mail me back. good luck, BMW Rider

It takes a long time for the tv to turn on

That can be a sign that the picture tube is going. Does the color look a bit off when i finally does come on? On the flyback transformer are 2 knobs 1 is labeled focus the other 1 screen. you can try to slightly increase screen voltage, that might fix it. otherwise it might be cheaper just to replace.

Sony Trinitron KV35V35

Could be a weak Picture tube . You can try turning up the screen control but don't turn it up too much you'll get retrace lines in the picture . Turn it alittle at time until picture comes on then turn it down until the retrace lines go away . Then try turning the tv on and off to make sure it comes back on. Be careful you can get shocked if you do this while it is on and you touch one of the circuits . The control is on the flyback or the module thats on the picture tube it will say screen by it . If this does not work you could have vidoe problems or just the picture is no good . Good luck

Flashing, slow startup, and finally, just snow

Try resoldering the pcb, especially the heat producing components on the pcb, do it with the crt base card too, I guess this will fix this up. Good luck.

Sony kv35s66: No picture, just sound and red blinking

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.

Sony Gurus! My set has sound, screen takes long to come on.

I will suggest you put the screen control back to where it was,the unit has a lot of loose conections in the power supply,horizontal driver transformer and possibly crt board,if you keep using it like this it will go dead completly and the repair will be more expensive,be safe and call a person who is qualified and get an estimate.
