EmersonEWC1902An Emerson TV/VCR Combo unit. When you power on the TV using the remote or manually at the TV, it comes on then shuts right back off.Can you hear any high voltage, when the TV starts? if not, try to measure the secundairy voltages, and so check if there are shorted ciruits on the mainboard! The primairy power supply will shut down when ever a short is detected on the secundary side (e.g. highvoltage or deflection circuit) 11-07-05
