Sony Trinitron Stand By/timer light continous blinking - cannot get picture to come on or how do I turn off the stand by/timer off so the TV picture can come on


Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.

Blue Screen and TV shuts off


Here's a shortcut to what the blinking codes mean.
http://www.somelifeblog.com/2007/08/sony-tv-led-blinking-codes-what-does-it.html
Strange how some people have 5 blinks. Most with this problem have 8 blinks (like myself)

I still have the blue-flash-then-shutting-off problem.. (8 blinks meaning voltage error) but I did fix the blue lines.. The lines across the screen can be very easily fixed whether they're blue green or red. . No, I mean REALLY easy. Took me longer to get the cover off. Once the front cover is off it takes 10 seconds. This link was also posted recently in one of the posts below as a solution..
http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html
(My lines didn't look like the ones in the picture mine were several evenly spaced blue arcs)

After some research I believe the flash/shutting off problem means the CRT is going. I've also read that it might be the D-board and I'm not even sure that that is... But If it is indeed the CRT then I'll let you know it's very difficult to find a replacement blue CRT as this part has been discontinued.. but I did eventually find an alternate to an alternate part (yes that's the 3rd alternate !)) online for $256. Here: http://store.tv-repair-service-salinas.com/8-733-649-35.html

If you're bold enough to attempt that then good luck and please let us know if it worked.
Or another alternative is there's a whole lot of Boxing Day sales goin' on right now.

Picture Darker When Changing Channels Sony KP-57WV700


I've had the arcing horizontal lines from time to time in all three colors (differing occasions). I dunno the correct lingo for this stuff, but having the same TV and fixing it myself here goes. It helps to have another set of hands while doing this. Also, eventually you will need to work in the dark so have a small flashlight handy. Put your tv on an unused input so you always have a "dark" background.

Open up the front panel of the TV.... There are phillips head screws running down both sides around the back side of the panel. After removing the screws and the little side panels they screw into, the whole bottom half of the TV can be popped off. Be careful not to pull it off to far as there is wiring running to the front panel controls. (you can disconnect the wiring plugs if you need the panel out of your way, just remember where and which way they go.) Behind the main silver panel is a smaller panel made of a thin pressboard type material. Remove this panel as well. Inside this second panel you will find 3 little knoblike controls (that also have a screwdriver head) that control the "color drive" of the corrosponding guns. They have a little strip of locktite on them to keep them from moving but it dosent hold on to hard. I'm telling you all this from memory and I'm sure the real techs out there head's are about to explode due to my cavalier attitude toward all this. I wish I could tell you exactly which one is the blue but i've adjusted them all at one time of another and can't remember which one is which.

Pick your favorite knob and SLOWLY adjust it to the right. Just a little bit....too much and your TV will pop off and you'll think you've blown up your tv. (I did this once, and had to uplug the tv and let it sit for a little bit before it came back to life, I probably got real lucky on that one)

Now...as you SLOWLY turn this knob, one of two things will happen. one.....another color arc is going to appear on your tv...this tells you you've got the wrong knob. turn it back to where it was. two....your blue arcs will brighten... thats the one you want. Kill the lights in the room...the darker the room the better. Turn the knob down (to the left) until the point at which the arcs disappear, if you go too far, that color will be "underdriven" so you want to hit it just right. It helps to have someone at the back of the room to better observe the arcs, it can be hard to do this sitting as close as you have to be to adjust the magic knobs.

Repeat if you have any green or red arcs.

Use some locktite on the knobs when you have them where you want them, i've used nail polish if I didn't have locktite available.

Rebuild your tv.

No picture blinking stand by light


I hve worked on a number of these units , your description is typical of a shorted blue picture tube. The protection circuits in the tv detect that there is a problem thus shutting the unit down to prevent further damage. Sony had a bad run of picture tubes in this series. The replacement cost of the tube is about $250 plus labor. My estimate would be for the repair about $400-500 depending on where you live and how honest your local technican is. I will caution you however, that you could replace this tube and the red or green could go. These would not be covered by the technicians warranty. When these sets are working, they have a superb picture and it is easy to get lured into fixing them. Scrivitron
