Lamp Indicator is Red


Its much more likely that your getting a 34 error which is a lamp abnormality vaused by defective capacitors on the power board. You can get the V26 DLP power PWB repair kit at the following link that should repair the issue. Chances are your old lamp is still good.

New bulb/TV still shuts down


Its far more likely the result of the power pwb capacitors that have failed. As the 34 code will appear if the capacitors fail on the Power PWB. You can get the V26 DLP Power repair kit at the following link.with free instructions

Had a solid amber light indicating a new lamp was needed.


Press the menu amd device/input buttons both in together on the front of the set and hold them both in for 6 seconds to see if the timer light will blink a two digit blink code such as 3 blinks, slight pause then 4 blinks. If it blinks that code you will need the V26 Power pwb repair kit which is available at the following link under repair kits and has step by step instructions.
