Right , if the indicator light goes from Green to Orange when shutting down , it will be the Powersupply that is giving problems and not the Ballast.

Trying to replace lamp in HDTV and having trouble. Does not function correctly after putting in new bulb. Boots up and then visuals go black and the green power light keeps flashing. Help?


Panasonic DLP TV Bulbs

Make sure its an original Osram or Philips bulb inside the housing. If its a cheap lamp it will act this way. If it is an original lamp, then you may have a power supply issue. It shouldn't affect your TV but you may want to try resetting the lamp timer by following the instructions that came with the lamp.

TY-LA1001 Timer reset

While pressing the VOL- button on the projection display, hold down the number 0 button on the remote control at the same time for more than 5 seconds.

The "lamp" light keeps blinking red. Does this


The lamp life becomes 0%, when used
for approximately 4,000 hours with "Eco
Mode" or when used for approximately
2,000 hours with "Standard Mode" (see
page 43).
When the remaining lamp life becomes
5% or less, " " (yellow) will be displayed
on the screen. When the percentage becomes
0%, " " will change to " " (red),
the lamp will automatically turn off and
then the projector will automatically enter
the standby mode. At this time, the
lamp indicator will illuminate in red.
If you try to turn on the projector a fourth
time without replacing the lamp, the projector
will not turn on.
If you require the manual to help with changing the bulb, send me an email to LBrown18062@hotmail.com Put SHARP PG-B10S in the subject line. I will send it to you right away. Lawrence Brown

After changing the bulb image will not come on and solid orange light appears


Other then POWER BUTTON light there are three lights more
1. lamp indicator
2. temperature indicator
3. computer input
witch one light is flashing RED or illuminated RED with POWER BUTTON orange light.
If LAMP INDICATOR light is illuminated RED than lamp runtime has reached 1800 hours. but projector still working.
If LAMP INDICATOR light flashing RED than lamp circuit failure, or abnormal function or lamp unit is damaged. In this case projector doing the same behave just like your projector.
if TEMPERATURE indicator illuminating RED the projector still projecting and if flashing RED than turned of itself

I turn tv on...green light comes on but i get no picture or audio....then light indicator blinks red


Hello!
Lamp or ballast(if lamp has been replaced) is bad.
Explanation: green comes on: system works, waiting for light to shine into light engine: no light is coming out of lamp, system shuts down, then you see red! how to determine: pull the lamp out of the unit's compartment. Inspect lamp: bloated stem? shuttered? reflector is not shiny? Chuck it!
Lamp looks good or just been replaced: try ballast. Close lamp compartment without lamp itself. Make sure, door is shut, as well. Turn unit on and listen close to lamp compartment: good ballast will make a buzzing noise, then stop. You've got "red'! No buzzing: ballast quit. Needs major repair! Lamp must be good, for sure, to get to the last part of diagnostics. Conclusion: more, than 2000 hours of usage: replace lamp first!
Good luck,
Alex.
