    I have an older (12-14yrs or so) Sony 46" rear projection tv. The screen has now gone black and the red blinking light is continuously on. Does that mean the projection lamp is burnt and I just need to replace that? The audio is fine.

    Thanks for any help.

I replaced the bulb in my Sony TV . when it powers on there is a warning that the bulb is about to expire

With the model number either Google "lamp timer reset" or call Sony; note that the lamp timer reset should be in the owner manual and is done with the Sony remote control.

My tv is on standby and will not turn on

Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service

KDF46E2000 - Change Lamp Warning - Reset

Bulb is most likely OK. Original bulb in Sony TV is Philips, label on bulb usually says Philips. Sony don't make bulbs. Sony Cost is usually 1.5 times other sources. Many shopping cart operations sell condemned, reject or poor quality electronic service items because cost of return and fooling with them is excessive. This is obvious and widespread with convergence ICs and other parts.

Lamp timer needs reset. This is usually an automatic function. TV detects Increased lamp current from previous failed bulb or weak bulb condition and resets automatically. TV must be unplugged for lamp replacement for this to work. Occasionally it must be reset manually, as below:

1. TV must be in standby mode. (Power off).
2. Press the following buttons on the Remote Commander within a
second of each other:
DISPLAY Channel 5 Volume + POWER .1. Access Service Adjustment Mode and select the Service Menu that
contains the Category with the Adjustment Item you want to change.
2. To change the Category, press 2 or 5 on the Remote Commander.
Note: Pressing 2 or 5 only changes the categories within the
Service Menu displayed. To change a Category on one of the other
Service Menus, press the JUMP button until the correct Service
Menu is displayed.
3. To change the Adjustment Item, press 1 or 4 on the Remote
4. To change the Data Value, press 3 or 6 on the Remote
Note: To go back to the last saved Data Value, press 0 then ENT
on the Remote Commander to read the memory.
5. To save the changes, press MUTING then ENT to write into
6. To exit service mode, turn the power off by pressing POWER .
Wait 2 minutes before restarting the set to allow the fans to
completely shut down or the Service Menu will appear on the screen.
