On board leds are red in colour

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.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

If the led is red that means its stuck in stand by mode which is an indication that you have a problem in the power board

Error codes are hard to find for Sony stuff.

The TV is on standby mode due to protection; some error in the board. If you have spare boards, try replacing it one by one, starting from display board.

Just parallel to Power LED button you find HDD or IDE LED button, the red coloured wire should be top and the white coloured towards reset connection.

If your picures are all purple it means that the green colour is missing. TV colour is made up by mixing Red, Green & Blue. Removing Green leaving Red & Blue makes purple. Study the green colour circuit for a fault and confirm that the green gun inside the tube is working.

Hi there
The front panel connectors are mainly,

• harddisk activity connector
• power switch connector
• reset switch connector
• power LED connector
• speakers connector
• USB connector

Harddisk activity connector
This normally comes red in colour and is labeled as HDD-LED
Power switch connector
This comes green in colour and is labeled as POWER-SW
Reset switch connector
This usually comes grey in colour and is labeled as RST-SW
Power LED connector
This is usually green in colour and is labled as PWR-LED
Speakers connector
This speaker will give different beep sounds during boot to tell the user if there is any errors. It occupies 4 pins, however only 2 is important for the function. Be sure to connect the red coloured cable to the positive polarity and the black to the negative.

Good luck and thanks for using FixYa!!

E05 and E06 is the error codes for a faulty stack flue sensor. try changing the sensor first is the cheapest. if that doesn't work check for corrosion on control board in which case will have to change out board.

Gauges reads as follow
Green LED = The fewer displayed closer to next service
Yellow LED = In conjunction with OIL SERVICE service or INSPECTION comes on when next routine service is due.
Red LED = a routine service is overdue.
Clock symbol in conjunction with INSPECTION = shows that an anual inspection is due.
