I have the pth5498 and my tv won't turn on. My

Timer is not the problem---the tick ticking sound is the shutdown circuit in the set that has been triggered by a short somewhere likely in the high voltage area or the convergence circuit---shop repair---says Akai but I suspect set was made by Samsung who owned that name at one time.

I have an akai 27 lcd tv which shut down while watching. No sound no picture but the power switch is flashing red.I don;t know if it is a power supply problem or a burnt out backlight.I haven't opened the...

I would suggest to start by measuring the voltages from the power supply to the main/back light circuitry. If the voltages are low or jumping up and down, that means a defective power supply.
If the red light is blinking, the power supply has a shorted component.
Let me know if you need further assistance.

No sound or picture

Try 2 things:
1. If you have a cable box with the yellow/white/red outputs, use a compatible cord to run the 3 to another input on your TV (ie input 1 vs cable). and/or
2. Do a Factory reset. Hold the "menu" button on your TV then on your remote hit "menu" then "8" then "select" and go to "factory reset". You may have to unplug the TV as it may freeze on "factory reset". Replug it then try it out.

Hope it works.
