Red light came on and said I need to replace the bulb? Panasonic said I could do it myself. How much does this cost to have repaired and is it worth it? The Tv is only 3 years old

Purchase a replacement lamp from somewhere like espares or the like.
It should be a standard E17 or SES 20Watt bulb.

This usually is a result of a failing power supply or any of the SOS circuit boards. Power supply's and boards are expensive to replace and in most cases not worth the cost to have repaired if you are out of warranty. However this is a known issue for Panasonic and I have seem them repair your model sets at no cost. So it is worth giving Panasonic a call and see if they will fix this for you. If they agree to fix it they will send a tech to your home for repairs.

Power supply for a red haze problem? Doesn't sound like a powersupply issue. If its a red haze that Im thinking aobut, you might as well buy a new set. It'll be a little too costly to fix.

When it was shutting down, what was the red light blinking before it paused then repeated?

Several failures can cause a red picture but it sounds like if you are connected from the source with component video cables(red,blue,green)you may just have a bad cable,but you may have had a blue and/ or green projection gun failure,which would cause the red gun to over power the other colors(blue/green), if this is the case definently not worth the cost to repair, you have to replace all three guns at the same time costing $500+ to repair, invest that towards a nice new LCD panel TV. Good luck !

ROTFL. That old machine doesn't owe you a dime. You can buy a new one with more features for less money.

Ur CRT need a rejuvenation,it a messy job.
It cost u the big screen repair shop about $300 dallors.

trust ME when i say setting convergence after doing repair takes alot of time to do /you can damage set if you do not have service codes and values/ you also must have the hand unit that comes with set in order to even get into convergence circuit, call your repair shops ask if they have a good blue tube for set and how much would it cost to repair?ARE you sure blue tube has been removed from set.?

It very well could be the ballast. I unfortunately have this tv and keep extra bulbs because they go out about once a year. Last time when I replaced the bulb the tv blinked and the red lamp light flashed like it does when the bulb is bad. Ballast repair kit fixed it up. This is certainly a design issue but you'll get no help from Panasonic. If tv comes on the goes out after a while, clean the fan filter.

i'm on my 3rd bulb in 5 yrs. i hate this tv. this time my bulb light didn't come on. instead the power light flashed green fast then went to red flashing after. i took out the bulb and it's blown!
