Display problem after bulb change

Everything was working fine when I changed my lamp. After replacement I turned it back on and the display was cut in half my a largeblack vertical line. THe top part of the screen was displayed at the bottomand the bottomof the screen started half way up. It reminds me of when the vertical is out on an old TV and the screen is slowly scrolling up. I hope that makes sense. I have tried evverything and have been searching for an answer for hours.

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.

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.

When you trun on my panasonic PT-61LCX65 tv it makes no sounds the light blinks green. and then red and turns off. what is wrong. i have looked at the buble and it looks fine.


Hello,

does the TV bring out sound even as the screen display is dark?

How long have you been using this TV and have you ever changed the lamp/bulb? Problem should be from the TV lamp/bulb.
Have the lamp replaced and hopefully, your screen should be perfect as before.

Let me know if you need directions in replacing the lamp, even though it is very simple replace.

Yours sincerely.

How do I change the bulb for the radio station display?


I'm assuming this is an LCD back lit display. To replace the lamps (usualy more than one) you will need to unsolder all the contacts on the LCD display. Usualy 20 or more contacts. The lamps are soldered through the circuit board and are usualy grain of wheat leaded types. Some lamps are wired in series so if one goes out they both go out. Others are wired in parallel in wich case one fails and the dimmer display is ignored until the other one fails. Usualy two 6v lamps for series or two 12v lamps for parallel. If in doubt try measuring the supply voltage to the lamps before removing the display.

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
Commander.
4. To change the Data Value, press 3 or 6 on the Remote
Commander.
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
memory.
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.

Tv cuts off and green light flashes


Yup, it seems a lamp problem can give a blinking green light over the 10 times (1 - 10 times for diagnostic codes), but in my case rather than replace the bulb if it works for a minute then resets with the green light blinking, do what I did.
Take the lamp out and inspect it, it has breather screens top and bottom, if it cant breath because there clogged with dust, clean them, and you can remove the screens, use q-tips and clean the inside. I saved the cost of a lamp and it's working fine!
