It is indication you have a failed ic. replace the 2 main ic components on the D-board. r two ic's with ic-8002 ic 6501 both are mcz3001D IC's they cost 5.50 each. Have a proffesional that can do soldering to the board and your fine. If not take it to a technician to replace the IC's on the dboard that are faulty.

This indicates that there is a problem with the backlight of the LCD-panel. Most of the time the inverter unit is defective.

In rare cases, the backlight is not switched on due to a problem on the BDT-board.

    there may not be replacement parts available in which case the complete LCD panel has to be replaced.

    Also are you sure it is blinking 4 times. Could it be 3 times?
    Thanks,

    I would advise not soldering it yourself though and having a certified technician. Knowing what the parts cost the job will not be very hard.

    2 IC's are bad on the main board they are part MCZ3001D IC.
    they are 5.50 each.

    sorry I meant they are on the D board.

    Lee A. Jun 16, 2008

    In any case a Sony authorized repair center would be the best place to bring it to. As replacing any and all of these IC's may not correct your problem.
    I hope that you will find this helpful,

The problem seems to be in Secondary supply of Switching Power supply.

SOURCE: TV doesn't turn on, standby light flashes 4 times

4 flashes mean the IC5004 (STV9379)on D-Board went bad and the 15V supply is no longer steady. The IC is rather easy to find and inexpensive (around $2.50). Your main problem will be desoldering the old one and soldering the new one. CAUTION! - Heat sink on IC5004 is -15V. Care must be taken not to allow heat sink to touch any other components

Good Luck.

My standby/timer light is flashing and will not turn on.


Hi,
The Standby/Power light of the TV blinks when there is any internal malfunction in the TV.
The self-diagnostic function of the projection TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue. As per the two examples below, some of the issues may be resolved without the need for service.
If the STANDBY light flashes three times in sequence, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
If the STANDBY light flashes four times in sequence, the TV may be overheating. To resolve this issue, ensure that the back of the TV is well ventilated.
If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.
If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
If the issue continues to occur, service may be required.

Television will not come on after low voltage surge


Good day.

Check on the horizontal output transistor, vertical transistor, and loose contacts along MICOM and system ICs.
