KDF-60XBR950 Red light blinks 5 times


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

Hi, if I change my computer to my Nissan 300ZX 1986 I have to reset my computer or simply change it. Thank you for answer.


There is no re-setting. You just change it out. Be sure and disconnect battery before unplugging the ecu. It's a simple swap and go.
If yours is like my '87 Sentra, there is no trouble code capability, but there are limited diagnostic functions. The red and green LED lights and the diagnostic switch (on/off), can tell you if problems are present in the system or not. You just have to follow the diagnostic procedure.
Here's how: Make sure diagnostic switch on ecu is off. Run engine at 2000 rpm for 5 minutes, at no load. Look at green led: if it flashes at least 5 times in 10 seconds (that is the oxygen sensor making it flash), turn car off. Turn diagnostic switch on. Turn key to on, do not start engine. Check led's: if red is off and green on steady-No problems present in system.
If the red light is on and green light is flashing, post back and I can furnish the rest of the diagnostic procedure-basically, you will be checking voltages and resistance of all solenoids and relays the ecu controls. The green led may flash in two different sequences (either longer flashes and short pauses, or longer pauses and short flashes) when in diag. mode (with the red led on), and that will lead you down two different diagnostic routes. Pretty simple, really, and pretty effective. Took me hours and hours before I realized I even had this diagnostic function.

Sony tv screen has no picture


Watch the red light and or power light when this happens, if there is a specific number of blinks and then a pause that is a error code.

How many times red light blinks? It is error code of problem in TV.
There would be pause of 3 seconds between blinks so count from pause to pause and let me know to find out solution.
