After all the discussions here and the occasional praise for Kroil here and elsewhere, I went to their website and purchased their Introductory Package.
 
I just received it from Kroil this afternoon. I will be testing it later today on some quite-vintage bolts on my wife's Volvo. If it is the Miracle-Formula as-promised, I will be quite pleased.

Just give it overnight to soak in. May work sooner on some things.
When working I used about a can a month or more, sometimes a can a day
dpending on the jobs. Just glad the company I worked for was buying it.
 
This was a very large plant and I bet we used over a case a week when
the company was going full blast.

A machinist friend of mine swears by Kroil, to the point of derision by others when the subject comes up. Many years ago, one of my buddies drilled out a steel plate and welded in like 8 bolts to it. We buried it in his back yard near the wetlands part of his lot and planned to dig it up in two years and use it as fairly well controlled test bed for various elixirs. Unfortunately, he moved and we forgot to dig it back up.
 
Most evidence I've found on the subject is anecdotal. Without a control there's no way of knowing if one of these solutions would have worked better or worse than any other.

I am no great believer in miracles and/or instant gratification. Overnight is good enough for me (and you are the second with this advice). stripped heads are no fun at all.
 
I am doing the fuel pressure sensor on a Volvo XC70, one (1) torx bolt. Also the MAF sensor, but that is a plastic part held in with hose clamps. No biggie.

I got a jelly jar full of Kroil from a neighbor.
It seems to be better than other stuff.. but it's always
hard to tell. I've never tried the 50/50 mix of ATF and acetone.

This was an LCD TV for what that's worth. One board was bought by a TV
shop, the other by an individual.
And count my chickens, I already gave the money away.
Saw this young women on Youtube and was inspired so much I made a donation.

Selling to TV shops is the best way to sell boards, but even they sometimes make a guess. Paypal is notorious at siding with the buyer on just a complaint, reasonable or otherwise.
 
Yes, your TV was an LCD, but other than the extraordinarily rare OLED, most TVs are LCD. The first LCD TVs were simply called LCD as opposed to the other flat screen tech at the time: plasma.
 
These TVs used CCFL tubes for back light illumination as LCDs are shutters and don't generate any light (unlike plasma and CRT).
 
Later, when manufacturers found a cheaper way to build back lights, they started using LED arrays to provide the back light for the LCD panel. These TVs are generally called LED, but they are still LCD TVs and use the same screen.
 
In the service trade, we refer to earlier LCDs as CCFLs and later ones as LED TVs.
 
The point of this is although you didn't post a model number, that model looks like an LED LCD, not a CCFL LCD. If it is an LED back lit TV, LED failure is common and when an LED opens, there are various symptoms, most of which duplicate bad power supply or bad main boards.

I think the TV shop just made a low ball offer, if it is accepted he
can stock it.

Just correcting the LED label from the previous post.

It had 14 CCFL tubes running across the back panel of the TV.
I also have the inverter PCB for sale, but at the end of a month I
will probably dispose of it.

No backlight LEDs to fail.

A BIG contributor to backlight
failure is the setting for it! Most
people do not go into the menus
for these flat panels, and just
watch it in default settings -
typically 'Vivid' or Dynamic
mode.
 
I calibrated my LED set last
year, starting with the backlight
lowered to halfway. Final
setting was 8/20, using Samsung's
scale. It is still plenty bright for
viewing where the TV is in my
house, looks awesome at night,
and neither myself nor anyone
else watching it has complained
of eye fatigue.
 
Moral of the story: Unless the TV
is intended for use outdoors on
sunny days, or on the sun deck of
a cruise ship(!), there is no reason
whatsoever to leave that backlight
at its maximum setting. This is
akin to leaving the Contrast
setting on an old tube TV cranked
up all the way. Which is why so
many of those hit the dump
prematurely.

Maybe 30 years ago, I replaced my cables with custom lengths with a solid core Soldered with a decent grip.
 
Now you have RG6 and RG59 compression RCA's which don't look like a bad alternative for non-flexible stuff.

That does seem to have a lot of them, but I can only view them page by
page. To download them, they require a CAPCHA. If I said what I think
about capchas, I'd be banned from the newsgroup for using foul language.
If I can even read the f**king things, they do not work on my slow
dialup system, nor do they work on my cellphone. I'd like to shoot every
one of the sons of a b***hes who use them idiotic things. They serve no
purpose whatsoever.

Doing a little research on my own, I ran across this site.
http://www.repeater-builder.com/radio-shack/radio-shack-index.html
 
It has info and schematics for a lot of the RadioShack Ham gear,
including scanners, weather radios, test equipment and more. They do NOT
encourage other R.S. consumer electronics (I wish they would), but it's
a decent site, even if it's a bit disorganized.
 
Best of all, no f**king Capchas......

Why don't you contact the owners of those sites and see if they would be
amenable to allowing you to set up a mirror of their manual collections?
That would go a long way toward insuring that the manuals would survive for
a reasonably long time (maybe outliving the site owners).

You can't be banned. Go ahead and cut loose.

The store I went to, all the small parts in the bins were $1. No matter
what it was. But there were little left.
 
I got Three 12V and One 24V power transformers for just over $2 each.
That was at 80% off, but the packages on them showed they were OLD
stock, thus old prices. I first grabbed one of each off the shelf, but
for that price, I decided to take all four. That's a steal.
