Call the service rep who did the work. They replaced the failed parts, but did not find the original cause of the failure. You should tell them that! Replacing the parts without finding the original cause will only cause the present work done to fail again.

Tv goes off after about 5 seconds


Bulb replacement is a good try, I would also have them come out to look at the set again as I am sure there is some kind of warranty on the parts.

I turn on the tv it beeps about 10 times no picture then shuts down


the beeping would be due to a failed power supply unit inside or a fuse there-of i would check this out before making costly repairs that will not work in the long run, hook me up with a good rating and have a good day!

I have a rear projection panasonic 51" tv with blue curved lines


This can be repaired by a Degaussing coil from most TV repair places. If you haven't already you should shut down the TV and wait till it cools maybe 1 hour or so and then when you turn it on there should be a degaussing circut that might clear this up for you build into the set. Its not that strong a signal and usually takes care of minor discolorations. If it doesn't have that then a shop can come and take care of it pretty fast usually.

Hi, have a 50 inch rear projection Mitsubishi. The problem is that the picture is curved and some of the words around the edges are doubled. Its most noticeable when watching sports because the score board...


power transistors in the convergence circuits on this series TV go bad after several years, making the wavy lines around the edge of the screen and 'doubling' of the edges of the text in varied colors which do not converge. Professional repair is required unless you are brave enough to tackle the project yourself and follow some rather simple instructions, buy a few tools from Radio Shack, and save yourself about $500 bucks...which I did on my own 42" Panasonic rear projection set.
