Have a six month old tv that has gotten too "green." Anyone know where
I might find a representative schematic of a modern CRT circuit so that
I could ponder the addition of a bias pot to the green channel? Thanks.

If the TV came with a one year warranty, I'd at least submit a claim. Many
manufacturers junk stuff under warranty and replace it with new units.
Usually I try to buy most cheap electronics at either Sam's Club or Costco.
Prices are usually the lowest found in retail and their return policies are
unlimited unless it's computer or food items. |

Warranty repair. Do not open up the tv and void your warranty.

RCA 14F512T
It's a little <$100 set so the parts warranty is irrelevant. If a $3
pot will save it from the dumpster that would still be a good thing.
Thanks. |

If it's just a little too green, you should be able to adjust it in
the service menu. Modern TVs have all the adjustments made via an on
screen menu, or computer interface instead of pots. I don't know off
hand how to get into the service menu of that set, but someone else
might be able to help you.

Just be aware that you might screw up the TV more than it already is by
changing any of the settings there, so before changing anything write down
what the value is, so you can change it back if it doesn't work.

That is very interesting. Thanks. So far I haven't gotten into service
mode but maybe if I try enough key combinations... I might find it... |

No...a lot of people here recognize the potential danger of giving out
information that will endanger a person or his/her equipment. Like it
or not, believe it or not, that is the simple fact.

OK...with my limited Internet access time, this "pig headed shitster"
has spent enough time to determine that this is a set that was likely
put out after I left this business in 2002. It may have a service menu
setting for adjusting the grey-scale, and indeed that may be all that
is wrong. It could be the CRT, or the circuitry that drives the CRT.
Instead of adding an unnecessary part to compensate for the problem,
you really should consider an actual repair.
To David Sewell...this "pig headed shitster", and many more of us,
have helped a lot of people get their stuff successfully repaired,
rather than destroyed...sometimes it takes a trip to the local repair
shop, rather than some hack job. Live with it. Take care.

According to another thread, someone else's kids managed to accomplish
it...
You also have to be concerned if it is the low or high green that is
the problem, or both. If you can somehow get a gray scale pattern into
the set, you'll be able to see this.
