No picture, has audio, front panel red light flashes. I was watching the tv when the picture brightness dimmed. It operated like this for about 4 hours and then there was an audible click and the screen went blank. After turning off and back on there is still no picture.

If you watch a DVD, does the picture also flash? If not, it might be just the TV signal. Are you using a cable/satellite receiver? If so, check it's connections. If anything viewed on the TV, using different inputs and a different cable/wire, is flashing, it is a problem with the light engine or color wheel, if the TV is DLP.
it works!! First i took off the front panel. Just check your manual
for instructions, very easy to do. If you do not have a manual just
down load one from google.. The instruction are easy to follow. The
screw they have you loosen with a alan wrench is attached to the
plastic, so you do not have to worry about dropping it inside the tv.
Removing the lamp was simple. once out you will notice on either side
are two small mesh screens. One of mine was 80% blocked with dust, the
other side was only 30-40% covered. I used a vacuum to remove the
blockage, i did not want the dust and dirt to go inside the bulb. i
then cleaned all around the lamp. Reinstalled, and we are go to go.
The kids are happy and i am happier since my wife not be buying a new
total cost of repair $.00
time required to fix, less than 15 minutes.
Also when my TV was loosing sound and picture and then return. I did
turn off my TV, then turned on. I nothiced a red blinking light. Mine
flashed 5 times. After some reserch, 5 times is video related, bulb or
video board. google red flashing light with the model you have and you
will find what all the codes mean.
So if yours is flashing 5 times try the above, it might work for you and it is well worth the time before you call a tech and drops hundreds of dollars.
If the picture is playing fine and you notice that the background is getting more and more red, until it is too red and the set shuts down, it could be that the red screen control is set just a bit too high. If this is the case, you can probably correct this yourself. If you are watching a perfect picture and then it suddenly flashes a very bright red, with thin red lines in the pictureand then shuts down, it usually means that the red picture tube has developed a short in it, between the cathode and heater. A good tech might be able to remove the short by arcing, but if the short persists then the red tube will have to be replaced. Either way, this is something that should only be done by a qualified tech.
