I purchased a floor model RCA less than a year ago and the colors have deteriorated to the point where no adjustment makes the image right. The brightness consistently makes all the white in the image bleed and dominates the image, and the other colors are also warped (or just generally dark). I have been trying to understand the problem so any possible remedies and guidance would be appreciated. Schematics and\or a service manual would also be useful...even a website for understanding the way a TV works would be great! Thank you in advance for any and all help.

Re: colors are distorted, brightness excessive
You may have a bad Fly Back transformer. The focus and screen(brightness) controls are located on this transformer. Some of the new RCA's have had problems with this transformer.
If the screen control opens up the picture may either go dark or light which would cause your problem.
Also a bad Picture tube could cause this. It shouldn't since the tv is not very old though.
I've seen a few new ones go bad.

The set should be transported upright but that rarely causes these issues-----suspect either main signal board or also possible is the power supply (for voltages changing when set is on).
Also if set was opened look for all plugs to be seated--ones with cloth tape where they connect look at first.
failing that based on age of set consider having a technician look at it or if over 3 years consider a new set with extended warranty--70% of this type of set in our shop (100 plus sets at any time in for repair) are less than 3 years old.
conversions are out....rca ... check for bad connections on circuit board around fryback xformer. check fuse by flyback xformer...fuse is shaped like a little plastic rectangle>>fuses should measure a SHORT when GOOD! Flyback Transformer is large in size and sends highvoltage to 3 picture tubes via a SPLITTER . easy to locate
This sounds like a problem with "convergence" of the TV. The convergence circuitry performs the electronic aiming of the Red, Blue & Green projectors. Typical
convergence problems result in distorted images on the screen such as: double or triple images on part or all
of the screen, wavy lines, curled edges, excessive red, green or blue
color or tint, etc. Sometimes, convergence issues can be corrected in a
menu setting of the TV that has to do with "Picture Settings" or
If the colors are out of alignment a great
deal or went out "all of a sudden" it will probably not be repairable
via the menu adjustment described above - but is certainly worth trying.
it does not straighten out with the menu adjustment, it will probably
require replacement of the convergence integrated circuit(s) chips
located in the TV. This was a "big ticket" repair years ago, but can be
done sometimes for as little as $40 in parts. Don't let the low price
fool you though.. It can easily take several hours (or more) to
access, remove & replace the components and reassemble the TV.
Soldering skills are a must - and I'm not talking about soldering
plumbing pipes here either. These are delicate electronic parts and
need a 15 - 30 watt soldering iron and de-soldering braid or "solder ******" and LOTS of patience to perform CORRECTLY. As such, it is "not a DIY project" unless you're willing to risk turning your TV into
a large floor model paper weight. If you decide to attempt this repair,
you should google your TV brand and model along with the term
"convergence". Parts, costs and procedures vary by TV. Unplug the TV
for a day or so before starting the work to let capacitors discharge
fully - just to be safe. Lastly, if you're going to attempt the repair - don't forget to purchase silicone heat sink compound -
it is an absolute *must*!
Check your oven for flame color; what you are describing could be deadly.
It is possible that you have an air vent clogged or blocked causing the flame to burn yellow indicating incomplete combustion and possible source of carbon monoxide.
This is very dangerous and I would strongly recommend you purchase a carbon monoxide detector.
We have one on the main floor and one in our basement.
A defective gas floor furnace in a home in a neighboring town 2 days ago put three children and two adults to sleep during the day and a 64 year-old man died of the fumes.
The others are recovering but are all hospitalized.
The family moved to Clay, WV from New Mexico only a week ago.
HELLO. YES U CAN IF YOU CAN GET A DEGAUSSER.!!! U CAN GO ON LINE AND FIND OUT HOW TO MAKE ONE AT UTUBE.COM. TYPE IN HOW TO MAKE A DEGAUSSER COLE.!! THEN FIND OUT HOW TO USE IT.!!! THERE ALSO.!!! GOOD LUCK.!!
if that's a dlp unit they are garbage ive had two and both died in same manner in less than a year one the bulb blew on in three months after purchase then went blank and started making a high pitched squealing sound had to argue with rcacust support after repair shop said they could not fix it rca finally sent me a new one but with less features after i argued with them for another three that one did the same thing after three months now rca wont even talk to me and ive got a 100lbs paperweight that does nothing i was told it was the light engine at a cost of around a grand for part so don't waste your money on a repair shop mine is still sitting there blank and i understand this is a common problem from checking the web just roll it in the back yard spend you money on one that will work im going lcd this time and i do houseld appliances not tvs so dont worry about rating me i like to pass this info on every chance i get just to help my friends at rca
