When I turn the tv on all I get is a quick flash of light why would the device do this?

I'd start with a replacement main board

graphical card issue or lcd needs replacement

If the TV does not stay on, press the POWER button on the control panel for at least eight seconds to perform System Reset. The TV will turn off. Power on the TV and the green LED will flash quickly for about one minute. The changes you made most recently, before using SYSTEM RESET, may be lost. If this happens frequently, obtain an AC line power conditioner/surge protector.

An unusual digital signal may have been received, triggering a protection circuit. Wait for the light to stop flashing and turn TV on.

Momentary power fluctuation caused the TV to turn off to prevent damage. Wait for the green light to stop flashing and turn the TV on again

Hi! I will be more than glad to assist you in this concern. this are the tv codes for sanyo. 542, 589, 590, 591, 592,
609. this is how to reprogram you remote to the sanyo tv. you need to press and hold the tv button that is on the upper portion of the remote, on the right side of the sat button. wait until all mode lights lit up, once all lights lit up, release it and then press number ex.. 542 then followed by the pound button, then you will see that the pound button will flash 3 times, it means that the code is program to the remote. note: while your doing the reprogramming of the remote you need to be in front of the tv about 2 to 3 feet away and the tv should be on.. granting u try all the code and none of them works.. try to scan the code of the tv by pressing and hold the tv button wait until all mode light lit up, then press 500 then pound, tv button will flash 3 times, lets say the last code is 500 and it did not work, press again the tv button and wait until all mode lights up, press on the re tv button if you have, but just incase u have only 1 red button for the power, press it once, then press the up button every 1 sec for 5mins. once the tv turn off then press the pound button and the tv button will flash 3 times, it means that you got the code for the sanyo tv, to check the code: Press the POUND (#) button twice. The mode button
flashes the number for each digit of the device code, with a pause between the groups of flashes. A quick flash is for zero. For example, if the code is 570, the mode button flashes five times, pauses, flashes seven times, pauses, and flashes once quickly... lets say that this remote works before with the sanyo and suddenly it quit working , pls call 1-800-333-3474 and ask for the replacement for the dishnetwork remote, remote is bad. please feel free to get in touch if you have any query..

If the lamp has been replaced I would think the Lamp ballast would be most likliest followed by the color wheel and then the Digital board. You can get any part needed for your model at www.tvrepairworld.com just leave them a email they respond quickly.
