Light bulb


White dot for DLP Projector TV is not because of the light buy. It is caused by aging DLP chip ( DMD Chip.) Your TV DLP Part should be the following image:

I have blue dots all over my screen aa well as


Hi,
This blue dot and hue problem is due to bad lcd in your tv as its Sony dlp tv that has optics block, that is also called light engine, it consists of 3 lcds, filters and lamp to produce an image that projects on front screen.
In this tv, blue lcd became defective and complete light engine will be replaced to get it fixed.
As other expert talking about blue CRT (cathode ray tube) that does not exist in this tv and my fellow expert has no idea about this kind of tv, sorry for that.
Hope this info will help you, let me know if you have additional question.
Thanks.

The tv has power , the volume comes on ,but no picture,just black screen. The red change lamp light has been on for some time,and it is still on


I believe this is a DLP set. There is a single high power bulb that shines thru the dlp chip and onto the screen. My old Panasonic 55" (forget the model) had the bulb access on the front left side-1 phillips screw to remoce the door and another to pull the light assembly. Replacement bulbs are available plain or in the assembly-your choice. Just google your make and model plus DLP bulb and you should be good to go- I paid $85 for the bulb alone- order 2 as the life span is much shorter than what panasonic claims- there was even a class action lawsuit over this issue that covered about 10 different set.

I have a toshiba 65hm167 no red color on the screen


Your TV is a DLP one lamp does it all, not like the old projection TVs with the Red, Green & Blue CRTs. Your TV may have a bad light engine or lose cable connections.

Good luck

Samsung 50" DLP - Lamp Light Blinking after bulb replacement


Listen closely. The tv should make a high pitch whine as it turns on. If it does wait and see if it tries this a few times. If yes then check the bulb, I have seen cases where the lamp shoves the power connector back into the set. If the tv starts with a grown or heavy vibration noise, then your color wheel may have broken and needs replaced.

Have little white dot's on screen will changing


Highly unlikely the bulb could be at fault; it sounds a lot like a defective DLP chip. If you are not aware of how this device functions, it is an array of physical mirrors which can fail individually and cause the effect you are having. The bulb failing would cause a loss of the entire screen, not just a few points.
