PLTV-32 We have a 32" LCD PROTRON PLTV-32 - We have audio but no video. We have tried the test of dimming lights, shining flashlight into display and we do see display on the screen. Our TV continues to come on after turning off/on several times (sometimes it takes hours; sometimes minutes-when we are lucky). Our problem is, we have been told by some that there are no "bulbs" and others tell us to "replace the bulb". If we have a "flat screen" is there a bulb? If so, where can we order one for this TV? If there is not a bulb, what exactly do we need to replace (backlight inverter?) and where do we get it? Our TV is out of warranty and there are absolutely no local technicians that can help us. Protron says to send the TV out to them but we are afraid the display will not make it (it seems so fragile).
