Vizio logo is an indicator that the tv is live n changes to white that the screen is on meaning if no change to white the smps switch mode power supply board ain't switching the mother board....diagnosis is its MOSFET transistors need replacement or the smps board n ya tv will be fine
i am having the same problem. My Phillips 37" 37PF9431D/37I LCD High Definition TV won;t turn on. When I press the power button i hear a click and the green light comes on for a couple of seconds and then the red light appears. I can;t figure it out. Did you find a solution?
Unplug TV straight away and contact Sony technical support on 0845 6000 124. If under warranty, will get repaired for free. Sounds like the Backlight lamp trying to switch on but something in the powerboard is preventing it.
If the repair shop says it is powerboard it means they already took a look at the TV and you dont need to worry about it. If you have any doubt please post the sympton here (detailed) and I can tell you for sure what the TV needs. I need to know what the led does and how it does.
finally got some help from customer service ----
the code flashing one then two red lights is for an upgrade of the software ---- you can go to their website and download a current fix to that problem onto a thumb drive----
\the power problem is caused by a bad power board--- you can replace them for any where from 130-330.00
dont need a service tech - take off cover and easy to replace---can find part on parts store.com for philips televisions --- used is about 130 and new about 330 -- used is a refurbished unit and works just as good as the new one
