    My Sony TV screen displays picture (using DVD) but constantly blinks between color and B&W. But I just tried watching a VCR tape, and it was perfectly normal! What is going on?

If the red LED blinks 5 times you have a AKB error. It is caused by the CRTs trying to balance the color, and failing. Its an annoying problem that happens when the CRTs get old. If its just beginning you can balance or slightly turn up the screen voltage to the CRTs to remove the problem, if its in the end stages, the CRTs may need to be replaced. This is however, very expensive. If you are daring and safe around high voltage, pop off the speaker grille, open the front panel up and find the focus block. Don't poke around! those big red wires have 30,000 volts running through them! The focus block is a black square box with six knobs on it. Three are labeled screen, three labeled focus. You will see each row labeled R, G, B for red green and blue. The writing is tiny. Mark all three screen knobs with a colored marker so you know where they started. Then turn each one up slightly. If you have a picture, put it to a black screen or blank input. Turn each knob up just unit you see the color over drive and turn it back down to black. You want to set it just below retrace to maintain black level but drive the CRT fully. Setting this is hard but may fix an AKB issue.

Tv screen will not stop blinking


It sounds definitely like a faulty power connection via the video cable from the inside. If it blinks a while then turns black then shows the picture, it would have to be that it's not screwed on properly, thus taking more time for it to get a full charge and then properly function. If you still have the warranty, any electric repair/retailer shop can fix it for you.

Sony LCD television will not power on.


I get 5 blinking red lights for about a minute or so before it powers back down. The Sony TV has a specific light that i presume is supposed to light up when the bulb is out. I'm unsure if this is what it is.
no picture, no sound. tries to boot with green light blinking a few times. then goes to red blinking light, six in all, then waits a few moments, then another 6 blinking red light.
Bulb was already replaced several months ago but we do have the TV on for long periods of time.
