Changing the "Lamp" in your TV.

So, you are going to change your "Lamp", yourself, in your TV? Well, all power, pun intended, to you. If you would, first, take some advice, from someone who has been doing all this, for over 25 years, it will be well worth your while.First, how are you 100% sure that it needs replacement? Second, Do you know WHY, the lamp failed? Now obviously, if you are replacing the lamp "Because the "Set" told you to" Well, then, that maybe OK. BUT, any other reason, could be fraught with peril. You see there are a myriad of possible reasons that the Lamp "Won't Light" and IF you DO NOT REPAIR the "Root Cause" then, either it simply will not work, when you replace it. OR, worse the "New" one you install, quickly fails. Due to the initial problem, simply causing the same "Symptom" again, which is/was the Failed Lamp. So you see what I am saying is, you must find the "Cause" of that Lamps failure, otherwise you are simply treating the Symptom & NOT the "Cause". You will just be spending good money after bad.Now I am not try to dissuade anyone from anything, I just want you budding would be "Fixers" to know what you are up against, with things like this.So, how do we know what, the "Root Cause" is? Now that's, what you should put your efforts into discovering. It is also the reason I make a living, because it's hard, somethings do indeed have, This-happened-so-this-is-the-only-fix. But more often than not, it is not a "Oh same as last time", type of thing. Components especially, semiconductors, just fail. It can be dry joints, faulty discrete components and so on. Now Often it is better to replace an entire "Module" than actually troubleshoot and find the actual "Culprit". Another thing that I cannot stress too much is try your hardest to obtain a "Service Manual" for you model unit, or even a close cousin. Also whenever you work on a TV set you should, always use an "Isolation Transformer" to protect you from lethal shock. Alright, so now you know what you should do right?

the interior lights will not come on when door opens, the visor lamps will NOT light no matter what, radio lights work normally the turn signal lamps blink fast, but all bulbs light

For the turn signal flashing fast - MAKE SURE you have all bulbs flashing that are SUPPOSED to be flashing. The front side marker lamps are part of this equation.

As for the interior (dome and visor) lamps, there is a fuse labeled "CTSY LAMP" in the fuse block. The lamps themselves are controlled by the body control module (BCM). The CTSY LAMP fuse only provides input power to the BCM. I would start with a scan of the BCM to see if it can shed any light (No pun intended) on your problem.

These units are famous for bad Capacitors in the DM module and power supply module. This is a very tight chassis and I would not recommend trying this one without some professional help. This is a real chinese puzzle (no pun intended). This should not be a real expensive repair. Thanks for using fixya. I am glad to help.

after tv is turned on it shuts off automatically

This is indicative of a failing lamp and/or dirty filter. The set keeps track of the hours of operation and trys to inform you when it is having problems. I ignored the signals and ended up with a blown lamp preceeded by my cleaning a dirty filter. On the bright side (no pun intended) my lamp lasted over 3 years without cleaning the filter. I was able to purchase a replacement lamp on ebay with overnight shipping and insurance for 160.00US, replaced the lamp and am back up and watching a better brighter picture.
