Question about Sony FD Trinitron WEGA KV-36HS510 36" TV
When I turn on my set it takes about 15 seconds for the picture to come on. When the picture comes on it will flash on and off for a long while. Then it stayes on and my flash of intermittently evey now and then. Has anyone had this typw of problem. Is it time for a ne set?
In most cases when I have seen this type of fault, the CRT was getting very weak. When the emission is below a specific amount, the AKG circuits keep it biased off.
It is also possible to have defective components in the CRT bias circuits, high voltage area, and the scan amplifiers that can cause this symptom. This type of condition is more rare to cause a flashing screen as per your description.
The TV making some clicks, and the red LED flashing is an indication of the power supply going in to the protect mode. This is usually from a scan amplifier failure, or a high voltage failure, a short in one of the circuit areas, and or a defect in the power supply itself. Proper troubleshooting is required to determine the exact fault.
