TV sounds like power up for few seconds then goes off
I have a Sanyo AVM-2503. When I turn it on, it sounds like it is coming on normally, then shuts off. The red power indicator on the front of the TV never comes on. Any ideas would be appreciated. Thanks.

Re: TV sounds like power up for few seconds then goes off
You have a short somewhere causing the power supply not to start. Most likely a shorted horizontal output transistor and maybe a flyback transformer which caused the transistor to short. It would have to be checked out by a technician to find out exactly

sound like a tuner problem. there is a resistor that goes to the tuner that could of went bad 39,000 ohms i think which should have a orange white orang strips around it and a gold. anyway there is a problem with tuner. Sanyo was good about haveing a problem with tuners in there smaller sets. If you do not know anything about how to repair you probly shoud take to a shop but the total cost might be high and not worth it in the long run. think before you jump still water runs deep.
Hi Hfrohman, This may sound crazy, but, press and hold the power button on the TV while unplugging it, continue to hold power button for 60 seconds or more. Release it and plug TV back in. Sometimes that will clear the settings.
I read your problem with the Sanyo PLV-55wm1. It sounds to me like a power supply problem. Like most new electronics devices, they use a switched mode power supply (SMPS)to supply the voltages to the rest of the set. Many of them use a current feedback loop to sense a short in the circuits that it powers. I would check for a shorted diode in the high voltage section of the tv. If any one of the components is shorted around the high voltage circuit, The current control line will be zero forcing the regulator to shut down.
This set is very popular for the capacitors to dry upa and go bad in the main SMPS as well as the switching power supply. If you have no know how on how to test capacitors or solid state electronics please take the set into a repair shop for an estimate
