Information about rear projection tv problem.? Answered

Hi Folks.
I tried asking this in the Tech Forum about a week ago but had no replys so I thout I would give the Q&A section a try.
I know there are some very knowledgeable people out there so I hope you don't mind if I pick your brains for some info ;-)
I have a problem with our Toshiba 46WH08B rear projection TV.
Yesterday I noticed that there is a distinct blue shadow around the images at the bottom of the screen this appears for about a 1/4 of the way up the screen the middle is fine as is the top right hand side but the same blue shadowing appears at the top left.
I have tried adjusting the convergence but as the centre of the screen is ok this does not really help.
I have done quite a bit of web searching on this & have an idea as to what the problem is but was hoping that there may be someone with some real knowledge of TV repair that could confirm my suspicions.
I don't really want to call out a TV repair man yet as I don't really want to get stuck with a bill just to be told it's beyond economic repair.
Thanks in advance for any help folks.
All the best.
Nostalgic Guy.


From what I've read, this problem is very common with rear projection televisions. Its the convergence circuit that has failed and will require a component replacement to get it working again. Its recommended that you get a qualified technician to do the repairs as these type of televisions can be dangerous if you don't know what parts you can and can't touch; plus you could also cause more harm than good.


I do minor TV repairs for fun, but I will not even touch these problems.. I always refer people to someone else.
