Lamp light LED shows red, manual indicates lamp failure. Replaced lamp, that didn't work, then replaced light driver. No change, lamp still doesn't work. On power-up, no red LED and projector appears to start up, fan runs for about 10 sec, (no lamp light) and then fan stops running. The projector appears to re-cycle and fan starts again for about 10 sec. This repeats for a total of three times in about one min, then red LED lamp indicator lights up.

I have that manual. There are three lights to the left of the power button. One is labled LAMP. The manual states "The projection lamp, which illuminates the picture, has a limited life. If the screen becomes dark, the color looks unusual, or the LAMP indicator on the front of the LCD projector TV flashes, it is time to replace the lamp with a new one (not supplied). Use a Sony XL-2200 replacement lamp (not supplied) for replacement. Use of any other lamp may damage the LCD projection TV." I also found in a different page " LAMP LED lights up in red when the lamp for the light source has burnt out." I guess burnt out would be extream. I found one other if you had opened the light bulb cover and didn't close it properly. " If the lamp cover is not reattached securely, the self-diagnostic function may be triggered and the POWER/STANDBY indicator flashes three times." You can down the sony manual at http://www.docs.sony.com/release/KDF60XS955.pdf
Panasonic PT50LC13 lamp indicator blinks to tell you the lamp is faulty.
You need to replace the bulb or TY-LA1000 lamp assembly. This link displays all Panasonic TV Lamps and TV Bulbs. This page shows Panasonic lamp location and How to Replace TYLA1000 bulb. TY-LA1000 Bulb Replacement requires the use of a long Philips Screwdriver to reach screws within the lamp cage.
Unplug AC power before removing the lamp and re-install all doors, etc, correctly before starting the TV. Vacuum any visible dust or lint from air vents and lamp area. Do not used forced air to blow out dust, big problems may result.
The user's manual has a description of what the Blinking LED indicators mean.
It is an indication that the projector is in sleep mode. Press power button and check for any changes on the led indicators. If the power turns red, it means unit is hot. check if the fan is working and if the air filter is clean or needs cleaning. If the lamp turns red it means the lamp is busted, You will experience this since lamp is clearly blown. But if both lights are red, it means that the unit is busted and will require service.
