tv repair plan
Got a 27" TV, several years old, that the vertical seems to have gone bad
in. All I have is a thin, bright, horizontal line approx mid-screen. I'm thinking of opening it up, pulling the vertical board, and replacing it. Should that work? |

Respectfully, if that's your plan, I would suggest modifying it to: "Take TV to reputable repair shop and have them repair it." --- sam | Sci.Electronics.Repair FAQ Home Page: http://www.repairfaq.org/ Repair | Main Table of Contents: http://www.repairfaq.org/REPAIR/ +Lasers | Sam's Laser FAQ: http://www.repairfaq.org/sam/lasersam.htm | Mirror Site Info: http://www.repairfaq.org/REPAIR/F_mirror.html Important: Anything sent to the email address in the message header is ignored.

Unfortunately, it's not worth doing unless I do it myself. I found a new
replacement set for $188, and I've been told the shops in our area will charge me at least $100 to fix it . They all want $50 just to tell me how much it will cost to fix (the $50 becomes part of the repair price if they get my go ahead to fix it). Just hate to simply throw the old one away. Thought possibly I could fix it myself. |

Have at it, but buy the service manual from the generic manufacturer, buy
the required test instruments, and required supplies. Also read Sam's excellent site illustrating the need for specific safety requirements before you even attempt to open the set, let alone service it by removing a "board". As He said, have it done professionally!! "RB" wrote in message ... Unfortunately, it's not worth doing unless I do it myself.

Some Wal-Marts are currently selling an FM radio receiver with headphones for one dollar! Consumer electronic servicing has officially joined blacksmithing as a lost art, for the most part. If you want to share your frustration, think about the folks who learned consumer electronics repair and are still too young to retire! |

Could just be bad solder connections but not something you are likely to be able to do yourself unless you have had some background in electronics.

From: "RB" Date: 7/17/04 9:35 PM Message-id: I found a new replacement set for $188, and I've been told the shops in our area will charge me at least $100 to fix it . Cheap shoes, cheap tools, cheap tires, etc. You get what you pay for. TVs that sell for $188 barely make it out of their warranty period. You'll get what you pay for, and often less. |

put finger to keyboard and composed: Got a 27" TV, several years old, that the vertical seems to have gone bad in. All I have is a thin, bright, horizontal line approx mid-screen. I'm thinking of opening it up, pulling the vertical board, and replacing it. Should that work? I doubt that your TV has a separate board for this function, unless it is eons old. In any case, the inside of a TV is no place for a board jockey.

Got a 27" TV, several years old, that the vertical seems to have gone bad
in. All I have is a thin, bright, horizontal line approx mid-screen. I'm thinking of opening it up, pulling the vertical board, and replacing it. More than likely, the vertical section may have worn capacitors and/or dry and cracked solder joints. Can possibly be a very easy repair, provided that you have the right tools and that you know what you're doing. BTW, most TV sets, including those produced in the 1980s, have the vertical scan circuit integrated in the mainboard. If you don't have any idea as to how to perform a proper repair and can't spend the money to get it fixed, donate the TV to a repair shop and buy a replacement. Don't get suckered into buying those Wal-Mart specials, though. They are cheaply made, usually don't last very long, and are usually backed by abyssmal customer service. TVs you ought to consider: Sony, Panasonic, JVC, Toshiba (higher end models only), Hitachi, Loewe, and Philips (higher end models only). Brands to stay away from: Funai, Apex, KLH, Sylvania, Magnavox, RCA, GE, Emerson, Orion, Norcent, Samsung, LG/GoldStar, Zenith, Sansui, Celera, Curtis Mathes, Symphonic, and Konka. - Reinhart |

Thanks for the good info. I'm not going to try this repair, as I have no
test eqpt (except for DVOM). If it was something easy like pulling and replacing a board, I'd take a chance on it. But, sounds like it could be small components on a board that isn't a plug-in. And, I couldn't begin to fault isolate, and maybe couldn't even replace a bad component. I don't have micro-min soldering/de-soldering eqpt. Just an old weller gun. |

Try giving it away, is there a section on craigslist.org that's local to you? Someone like myself could pick it up and put it to use. |

But RCA and GE is one and same
and much better than rest of this junky things on that list but why RCA (thomson) is NO good? Some chassis made by Thomson are okay, but there were a few, especially those with the infamous horizontal tuner module, that were, IMO, junk. There are also a few surface mount parts in various Thomson chassis in critical sections which make servicing more difficult. Plus, while Thomson does make very good picture tubes, it's a pain to have to replace an entire tube if the deflection yoke ever goes bad since the yoke is bonded to the tube. What makes it worse is that Thomson tubes are used in a lot of different brands, including JVC and Hitachi. Fortunately, the yoke is an item that rarely fails. I still stand by my opinion and I frequent a TV/Stereo store where the salespeople always refer to RCA products as "Return Comin' At'cha," a generalization that applies to any Thomson product. And, in an unusual manufacturing defect in a Thomson set. A customer brought in an RCA TV to a repair shop that made a loud POP and would not turn on anymore. Turns out the failure was caused by a stray resistor left in the horizontal drive section that eventually managed to work its way in creating a short in the high voltage parts. Another Thomson defect that was returned to the store I go to: An RCA TV stopped working and an unusual smell started coming from inside the enclosure. Turns out someone left a rather large piece of food inside the TV which managed to short something out and get cooked in the process. - Reinhart |

That's hurts. We liked them because of info and we do them and actually made money and speedy service and made customers happy as well. JVC is fine but very little in way of training stuff, same with Samsung, I found many Samsung's undocumented items that techs should know about. To get a factual idea of which TV is better or worse one should know the actual numbers of a particular brand and model sold in one's area. Only then, the service required for each brand - model makes statistical sense. Otherwise, it really does not sum up a true picture of which brand - model is good or bad.

Well I would agree that they do fail often, though they're a quite solid design aside from that and the faults are well documented, I certainly don't mind when one shows up, they tend to be good sets once properly repaired. |

tv repair plan
So a new tv costs 188$ and you can buy that but you cant afford 100$ to
get one fixed .. that never made sence to me . However 100$ to get the vertical fixed is robbery it probably only needs 8$ worth of parts and 30 minutes of the repairmans time .. i have done these many times . I used to repair consumer electronics for a living but do other things now but still repair the newer stuff that is bought as salvage where i work . I know the way most repair shops charged way to much to do simple repairs . Unfortunately these days in order for the repair shops to keep their doors open they must charge high because of the growing number of non servicable electronics coming to them . It sad but true . I still know a `service only` shop in town where we take some of out high dollar stuff such as big screens and plasma .... he charges the general public pretty stiff prices to fix simple vcr`s for a cleaning . Saying this makes most repair guys mad but its true .. My own brother still has his own shop and has become so poor he has turned half his shop into a gift shop of strange useless junk . Replace the vertical chip and see if that works . You can probably get a chip for around 10$ . |

How can it be robbery if shops have to charge those rates to keep the doors
open? Can't figure your logic. You seem to understand the reality of the costs of doing business but are unwilling to pay for it. You are worse than the idiots that think we are getting rich.

A goodly part of that attitude is the legacy of the "tube jockey" days... which some of you other older folks may remember. The rest is just evolution.

When I buy a quart of oil, I pay an addition disposal fee. The same for bottled soft drinks, and more. So, my suggestion. Why doesn't your government charge a *hefty* disposal (call it what you will) fee for new electronics? And fridges, stoves, furnaces, air conditioners, ad nauseum? Use those extra funds to educate your youngsters. It sure sounds logical to me. Sorry for the rant. Hadda get it off my chest Ken |

Hadda get it off my chest Ken I see your point, but the money would just go to support other countries "first" rather than our own. We're too worried about others. Rather than depending on China for "most everything", we need to become more self reliant. I'd be willing to pay a bit more for good ole American products. Most of the stuff anymore is pure junk, THAT is why the landfills are piling up. L. |

There's unlikely to be a "vertical board" and even if there is and you pull it out, chances are a replacement is not available. The good news is that loss of vertical deflection is an easy fix relatively speaking, and a good one for the beginner interested in TV repair to attempt to tackle. It could be as simple as a cracked solder connection at the vertical output chip, worst case the chip is fried, likely taking out a fusible resistor supplying power to it. Should be able to fix it for under 20 bucks if you have a soldering iron, rosin core solder, and a multimeter, which is also inexpensive these days. 95% of it is just knowing what to look for. |

Oh yeah, I should add, before you go poking around in there READ THE FAQ, TV's can be quite dangerous, but with some common sense they're perfectly within the reach of the novice, just take a few simple precautions. |
