Question about Sony KV-36XBR400 36" TV

Picture is going fuzzy and blinking red light...

First off...the little red light is blinking 5 times, all the time. Second, the symptoms. When the screen would normally go black between commercials, it's more greenish and we've noticed the left hand side of the screen is blurry. Before we spend the bucks on a technician, we'd like to know what it is we're probably looking at for a repair. Thanks for any assistance.

My is 32". Picture blinks while tv is on and takes about 1-2 minutes to receive picture when you turn it on. Blinks real fast and then about every 10-20 seconds after tv warms up., Picture is poor quality for Sony.

Any ideas why, appreciated.

This is the classic symptom of a CRT (picture tube)that is starting do get weak. The picture takes longer and longer to come on, it appears greenish and blurry, and it blinks on and off in different scenes, and when it is off the timer LED blinks 5 times. Sony has a circuit called "IK Blanking" which monitors and adjusts the colors in the picture tube, and shuts the picture off when the tube is getting too weak. The good news is that the Sony tubes always respond beautifully to a CRT rejuvination (recharge), and the picture returns to perfect. Since the set is 36 inches and VERY heavy, it should be serviced in-house and an appropriate charge for a service call for your set should be around $150.

My hp compaq doesn't work when i branche the cable of alimentation it signe with red

How many times does the red light come on ? It should blink a number of times, then go off for a little while, and start blinking again. The number of blinks within each cycle will help you find out what is wrong:
Number of 1-second red LED blinks followed by 2-second pause, then repeats:
2-processor thermal protection activated
3-processor not installed
4-power supply failure
5-memory error
6-video error
7-PCA failure (ROM detected failure prior to video)
8-invalid ROM, bootblock recover mode
