SOURCE: When I turn the TV power on, the TV picture won't display, but the timer display (red blinking light) blinks momentarily and then clicks off. What is the problem and how much would it cost to have rep
check the horinzontal out transistors. call qualified personnel to fix.

You can only reset the TV when you have the remote as it requires holding down the RESET button on the remote control, then pressing the POWER button on the TV front panel. The TV will turn itself off, then back on again. Then release the RESET button.
Regarding your problem with the TV not staying on for 3 seconds, you can try unplugging the unit for at least an hour to perform a hard reset of the microprocessor. If the unit still doesn't stay on, you need to check the power supply or the entire board for any blown or bad capacitor, shorted terminals due to accumulation of dirt, or broken solders. It may be a tedious task and requires an electronic prowess to do.
Kudos and thanks for using Fixya.

There is a fuse inside the power supply bard of your sylvania TV. Check whether it has blown out. If bllown out, replace it with same type bothe in size and amperage. If the newly inserted fuse also blow up as soon as you switch on the set, make sure that the power supply section has some short circuit in it, and should be cheked well. OK.
