Blinking a black screen on and off.

I have a Sony 32'' T.V. and it has started blinking a black screen, about 12 times in a row, then stops for a few minutes then does it again. Would my picture tube be going? Can you please let me know?? Could it be coincidental, I recently changed to digital??
Thank you very much for your response. -Claire

Picture tubes do not "go out" by going black: Your TV has a power heat-related issue. It is trying to come on but, the protection circuit is preventing it.
As; opening it to dust it, is dangerous; I suggest you take it to a good tv shop.

Sony KDL-52w5500 black screen 13 blink then 14 blink


You have a couple of problems if you are sure there are 2 different blink codes. 13 blinks indicates a backlight balancer error which would explain your no light condition. 14 blinks would be a TCON board error which is the driver board for the LCD screen. Either error would keep the screen black.

Sony Screen keeps Blinking


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.
