Hello
If the lamp replacement light comes on, surely there will be issue with the lamps; and should be replaced. But the flikereing of colurs will have an other probelm with video card. Chroma section may be some fault with it. Just check the antena if your are using and seeing on-air programme. If you are using cable, check the socket ottection at the backe of the tv for firmness. If connections have some loose contact, or not well tight up, colour flikering will occur. If all the connections are OK and just replace the lamps and see the effect. If this does not help you , replace the chroma card. Consult nearest philips service center for replacement. For lams alos, replace it with original ones from Philips. OK.

Power cycles but never starts


You said you'd tried a reset - both types!?

Hold these keys down simultaenously - ALT+RIGHT SHIFT(CAP)+DELETE

Power back on.

If that doesn't work - try a double soft, where you follow the above, wait until you have a blank screen and then repeat - You should get another blank screen followed by the hourglass.
