Sweet! Scored a nice Samsung 32" LCD
This 2008 Samsung showed up at the Thrift store a couple weeks ago, price was $225 Remote included, not too bad if it was working but this one was dead.
Today was 1/2 off on everything, still too high to gamble on at $112.50 so late in the afternoon I made an offer of $50 and it was accepted. I took off the back and found (what else) one of the Caps had blown it's top, only one and it's an oddball looking one that's a different brand than all the others so maybe the others are OK. It's a 2200@10v, I had a 3300@ 6.3 on hand so I put it in and now it works! The 6.3 volt cap is running cool but I'll get a correct cap before I button it up. This will make an excellent bedroom set, it has mounting holes for a wall mount. Here's are some pics. |

Looks like a 2200 uFd/16V 105°C Low ESR cap would fit the bill there. I wonder how many LCD sets get junked for a capacitor?

LOTS if its a Samsung. I have a 19" one here thats sitting in the basement. Eventually I'll spend the $30 and see if its a bad power brick (its external). There really aren't any caps in the set itself, I think the small PCB the power switch is on is bad though. Getting replacement parts, or even another dead/broken monitor has proven impossible.

Also, just to add to the thread. Had one of my 206BWs die. Bad caps in the P/S, so I ordered up some and did an across-the-board replacement on all three of those monitors I have. Two were made at the same time, and had bulging caps, the third was made a month later, and had a different panel, and the caps were fine. Replaced them anyway for peace of mind. |

I replaced it with a 940MW (its 1440x900 19" widescreen cousin), which also has documented cap problems. The biggest difference is that this model has the power supply built into the monitor vs. a brick. If I ever have a problem with it, the model was popular enough to market re-capping kits which are readily available on ebay. |

Looks like this is a very common problem for this model.
I typed the model number into Google and most of the hits were of the "My Samsung won't turn on" variety. Fortunately it's a very easy fix. The insides of this set are amazingly bare, compared to my Plasma which is packed full of circuit boards and components this almost seems like Magic that it works! I realize of course that there are actually millions of transistors and whatnot etched into it's little Silicon organs. |

I recently read in "The Basics of HDTV" that most flat panels today are in fact packed with circuitry, though most of it is unnoticed because it is contained within integrated circuits (ICs). In fact, I was amazed by the sheer numbers of circuits contained in these chips when I saw the block diagrams of the sections of a typical HDTV. Who would have thought, 25 or 30+ years ago, that this much circuitry could be crammed into a very small IC chip, or that an entire television could fit into a cabinet under one inch thick?
More amazing, to me anyhow, is how today's FPs can be made so slim. My own Insignia 19" flat set is only about an inch thick, if that much, and weighs just under 6.6 pounds without the table-top stand. I was amazed when I set up this TV in place of my 12-year-old analog one; the flat set is so much smaller it all but floored me. I bet a lot of non-technical people, used to seeing a large console or table-model TV in a huge cabinet, are amazed as well that such a small device as a modern FP (even a large-screen one) is a "real" television set. Because all FPs bear little or no resemblance to the large portable, table and console television receivers that preceded them (and which most people old enough to remember them are used to), such a reaction would not surprise me. What is probably more amazing to a lot of people is the idea of hanging a TV set on a wall, like a piece of framed art. This used to be science fiction (who would have so much as dreamed, 40 years ago, of doing that with a heavy 1950s-'60s vintage portable?), but today's FPs are light enough that it is now possible to do so -- even though it takes a special type of mounting to safely attach a FP to a living-room wall. The online instruction manual for my FP (and probably every flat-panel ever made which is intended for wall mounting) makes a specific point of this, and cautions the set owner that "one size [of flat-panel television wall mount] does not fit all" as well as stating that only a wall mount capable of supporting the set's weight must be used, lest the set falls off the mount (when the latter breaks under excessive weight) and shatters into a million pieces. I've never actually seen this happen, but it may well have happened in the past when someone does a slap-dash job of mounting the set to the wall or uses a flimsily-built (or the wrong size) wall mount.

In the 60's I would not think that mounting a set on the wall was sci fi. There were large deflection angle monochrome CRT sets coming out in the last couple of years of the 50's that were VERY thin. Infact I have an ad for a compact GE monochrome TV stereo console where they say that it can be set on a table, on the floor (with optional legs), or HUNG ON A WALL.
Infact I seem to recall reading a vintage article where an industry man is asked about what he thinks TVs will be like in the future, and he says that he envisions that eventually Tvs will be thin enough to hang on a wall.

The idea in the 1950s-'60s of a combination TV/radio/phonograph that could be wall mounted sounds incredible. How on earth did GE build that set so light and compact that the whole thing could be mounted on a wall, without causing the heck of a safety hazard? How many of these combos were made, and for that matter, how many different manufacturers made sets like this? I would guess not very many, and of those that were sold, I don't think many of them wound up on walls -- I would imagine most folks who bought these also invested in the optional legs, and used the sets as consolettes. RCA offered some of its mid-'60s metal-cabinet color sets (I had one) that had threaded holes in the base for legs, sold separately from the TV itself. BTW, the man in that vintage TV article you mention was right on, as today's flat panel TVs are thin and light enough to hang on walls; in fact, a lot of folks do just that. I know someone who did this with a 70"(!) flat panel and turned one entire wall of his living room into a large-screen movie theater.

Not ON walls, but IN walls was what several family acquaintances and a couple of neighbors did back then, pretty popular thing to do. I can recall several who cut holes in walls and mounted the TV flush with the wall and framed it in, with the set in an adjacent closet, room or in one case I remember the TV was sticking out into the garage.

Replacing old worn-out TV chassis in big 3-way consoles was also popular in the '70s. Two of my great-uncles, both long deceased, had large combo consoles in which the television chassis failed after 25 years or so, developing expensive repair problems, so they decided to replace the TVs with modern sets -- retaining the stereo components. Both consoles were RCAs; one set's TV was replaced by an Emerson table model, the other's television was replaced by a Zenith CCII, IIRC. I wish I had pictures of the converted sets, as the conversions were very well done; they both looked like factory jobs. Today, the only way to even come close to having a 3-way entertainment center is to buy a large armoire or EC cabinet (or a stand, like I did with my components and which I still have, now with a flat screen TV on the top shelf -- replacing the RCA CTC185 which once graced that spot) and install your TV, video and stereo components in it. We will never again, unfortunately, see the likes of the large, stately 3-way consoles popular in the '60s and '70s, the trend now being towards nondescript-looking FP sets on their jet-black stands. The only things that make today's FPs look good in modern living rooms/dens/family rooms when they are turned off, IMHO,are the entertainment-center cabinets or stands in or on which these sets are often mounted, along with a VCR, DVD player, and often a 5.1-channel AV receiver. An old friend of mine has a floor-to-ceiling entertainment center in his family room (which is huge), in which he mounted his TV (formerly a large Toshiba CRT, now a large FP), DVD and stereo system. I saw the installation some years ago when he had the CRT TV and was amazed at the size of the EC cabinet -- but I guess I shouldn't have been so surprised, since his family room has very high ceilings.

This flat CRT design is from the 50s... The Aken CRT:
