Re: Mitsubishi TV problem

Not an uncommon scenario. Lots of techs assume that a vertical failure is
just that, something in the output stage. This is especially true when you
find the leaky caps and perhaps a blown output IC that these sets usually
have. The problem is that there is more wrong with the set, likely the 12v
supply, at least. These sets tend to have leaky caps in several areas. If
you don't get them all and repair the corossion and bad solder joints, you
will have more problems soon, and sometimes you won't fix the immediate
problem.

We will not service these without going over every polar electrolytic cap
for leakage, and testing the ones in key areas for ESR. Customers often
balk at the higher cost of repair, especially when some yahoo garage tech
says he can fix it for $100 after hearing it has a vertical problem. The
fact is, if you just look to the vertical output circuit like you would
expect, and don't pay attention to the rest, you will not fix the set
reliably, perhaps not at all.

My parents have an old(1996} Mitsubishi console tv. Recently the
picture went out except for a thin white line running horizontally
through the center of the tube. The rest of the picture was black. The
tv still had sound. A repairman came out twice to try and fix it but
still has the problem. My parents like the tv because of the wood
console. I want them to buy a new one, but they are old fashioned. They
don't like the look of modern tvs. What could be the problem with it, a
bad tube maybe? Perhaps some loose wires?
