Question about Samsung DLP HL-P4663W 46" Rear Projection HDTV-Ready Television
T.V. shows lamp blinking even after new lamp installed. ballast was replaced 6mo ago. any suggestions?
SOURCE: ballast on samsung hlp4663w
The transformer can't damage the new lamp. Faulty transformers normaly take out the driving transistors or the fusible link in the power supply, if these are good then just replace the lamp. Espacially if you know the lamp is bad (test it by swapping with the others if unsure)

Is the Lamp ok? Go to the rear of the set and turn on the set with your remote while looking at the vent slats. If you can see a bright light through the vent slats then your Lamp is working. If the lamp is on and you have sound and no pix, then the Digital bd is in what we call "Video Mute" and will have to be replaced. Also make sure that the Lamp Door is installed and the screws are tight.

Any light blink on the front. Whats the voltage to the ballast from the power supply. Common problem on these sets are bad lamp door switch. Try shorting the switch. Color wheel also is problematic but usually will be noisy and cause shut down. Check power board for swollen capacitors. Hope this helps

Strange colors and flickering picture symptom shows problem with color wheel and/or dmd board.
Lamp is only light source in dlp tv and it has nothing with colors or picture flicker.
TV goes to protection mode because of some internal problem as mentioned above.
If you wish to repair tv by yourself then you should have service manual copy in hand and that can be downloaded from HERE for small fee.
Hope these info will help you.
