Default Is my RCA TV toast !?

Hi. I have a 27" RCA television (F27671SE). When I bought it about 7 years
ago, it was top-of-the-line, with picture in picture and colortrak plus.
Recently it has been acting up. I have it hooked up to standard cable TV
here in Michigan and have an intermittent problem. When I am watching
higher number channels the picture moves down and there is black on top and
you cannot see the bottom of the screen (like where the sports ticker would
be), the sides stay fine. When this happens, I lose the lower number
channels to snow altogether. If I power the set off and then on, I get
everything back for a little bit then it may act up again. But the problem
is always the same, picture moves down on high channels (anything over 14)
you can see fine but missing a chunk and channels under 14 go to snow.
Somedays it will work for hours and somedays it will act up for hours. Any
ideas?

Thanks much.

Do a web search regarding the class action lawsuit against Thomson
(RCA/GE/Proscan) regarding the onboard tuner failures.

There is also information at www.repairfaq.org regarding the chassis that is
used in the tv set, look on the back.

Be forewarned this is NOT a repair for someone without lots of electronics
and surface mount desoldering and soldering equipment. I have seen way to
many of these that were toast after someone ill-equipped and ill-experienced
tried and failed a repair attempt.

If you can take the tv into a repuatable repair shop that has lots of
experience, and is willing to do the repair the correct way per the service
bulletin, total repair under $90 typical. If you wait, the eeprom will
likely be corrupted and then you are looking at some parts and labor time.

The question, is the tv worth fixing due to the age and average cost? Only
you can actually decide.

Where in Michigan are you located?
If you are in the Southern/middle part near I69, I would be willing to pick
the tv up if you were going to send it to the landfill. At the very least
if you decide not to repair the tv set, many shops will accept the tv set to
repair and keep out of the landfill. Most of the better shops I know fix tv
sets like these and GIVE them away to places like: Womens Shelters, Church
youth groups, Half-Way houses, etc.

Thanks David I think I pulled up the right guide, but I am not certain. My
chasis is CTC177BF. Is there anything I can do in regards to reseting the
eeprom myself via the remote and/or buttons, or must it be opened?

Thank you very much.

You probably just need to resolder all the places where the metal
shield that covers the tuner connects to the circuit board. If you
wait too long, you may lose the EEPROM data and then you will have
tuning problems.

You should carefully read David's email. The set will need some work done
on it by someone who is skilled on your type of set and has the proper
soldering tools for the job, not software programming at this time. As for
the software set-up (going from memory for this type of set), there is some
dedicated specific programming hardware required. The service manual would
be a necessity if the tech was not totally familiar with this set.

Bad soldering on the tuner ground shields, stop using it now before you
corrupt the eprom and need even more work done on it. If you take it to a
shop immediately it should be a fairly inexpensive repair.

Just wanted to thank you for your help and advice. It was critical in what
I ended up doing. I shopped around between 3 local repair shops, of course
all of them could not quote me w/o seeing the unit although I supplied them
with the all the information and knowledge that I now had about this
problem. I got one guy's ear and he repaired the unit for $95 dollars. I
am happy so far, although moving that thing to the repair shop and back in a
foot of snow was interesting ....

I also called and than wrote (by the representatives request) a nasty-gram
to Thomson for never being notified of the problem in the first place. My
letter is currently in the mail to their review board requesting some sort
of explanation. The only one the phone representative could give me is that
I did not register the product ... anal me? Not register a $500 television,
come on ... whatever ...

Thanks again!

Glad you got it fixed . That repair does not require any special tools
just a good soldering iron .
I have repaired close to 100 of those and it takes about 15 minutes .
95$ was very steep . Some Repair shops love to see those coming so they
can charge way to much .... and a few will argue that but those are the
guys that charge to much .
They would not give you a quote so they could charge you the check out
fee when you take it in . Anything to make more .

A proper repair of this problem takes way over "fifteen minutes".

Thomson's S-kit solder and flux should be used, and ground wires physically
run to prevent recurrence.
