I have a 28" widescreen Philips TV. Model 28ML8916 Its about 3 years old - bought secondhand. It seems to be still switched on, btu the screen is blank (though you can see its alive), no sound. Symbol lights are all flashing in the bottom left control panel corner. The manual says - if you see and hear nothing and the lights are flashing, it means there is a malfunction. If i try to flick through channels, one of them (probably the AV channel) has sound, still no picture. I have tried many times to switch off, unplug, and then on again - but it didnt help. Questions: 1) Has anybody experienced a similar problem with a similar Philips TV? What was the problem? 2) Is there an easy way to fix it myself ? 3) If I have to get a technician, how can I make sure they are honest and wont try to rip me off? Any ideas will be appreciated!
