Looking for repair ideas on a projection TV.
I have a ProScan 60" rear projection TV sold under the RCA brand name. It
has been professionally repaired once with a replacement of a "flyback" and a "capacitor set". It is 5 years old, and the former repairs were performed 11 months ago. My current experience with the TV is as follows: The TV will work normally for about a week, and then it will stop responding to the power button on the front control panel and the remote control. You also do not hear any of the telltale signs that power has been activated such as components charging up and (I believe) a relay triggering. If you unplug the TV for approx. 24 hours and then plug it back in it will operate normally for the next 1 to 7 days, then it will begin a similar cycle. Intermittently, it will lose audio during its time of "normal" operations (which I usually don't notice because I tend to use the TV for video only). I shy away from professional repair because the last professional repair cost me over $450 and I don't think the TV is worth too much any longer. Any suggestions on repair (self or suggested service) are appreciated. I have done basic circuit board soldering and de-soldering, but do not have any skills in circuit tracing, etc |

I have done basic circuit board soldering and de-soldering, but do not have any skills in circuit tracing, etc It sounds like something relatively simple, if you know what you're doing and have a good eye, look for dry or cracked solder joints around the tuner ground shield (not sure if Proscan PTV's suffer this but direct views certainly do) if it still has the problem then look for the same thing on the power supply board. If you don't know what you're doing I highly suggest having a pro look at it, if the picture is still good when it works it should still have some life left on it, if you poke around without knowledge you could easily do a lot more damage. |

I have done basic circuit board soldering and de-soldering, but do not have any skills in circuit tracing, etc I would check the power supply for the entire unit. Soft on switches and standby start-up circuitry keeps this power supply up, and the only thing that changes on start up is the loading. If it fails, and then requires a rest before working again, it sounds like dried out electrolytics on the supply or perhaps the IR/soft on circuitry. Electrolytics are always the first thing I check out on older power supplies. I know that 5 years isn't very old, but there have been some bad batches made over the years. I recall a motherboard recall at one point where the electrolytics had bad paste mixes in them. Anyway, that is a likely culprit. Another might be enough dust on a part that it doesn't give up its heat well, and eventually runs away. Be careful of the anode leads on those guns. Projection sets have some mean juice there. Another alternative is to bypass the soft start altogether, and use a hard switch on the unit. Some of the convenience takes a hike, but it makes it a working unit again. Must fully power down (unplug) to save juice in the interim times though. Now I just knew that if only we could all be sufficiently patient, you (Dark Matter) would and could rise to the occasion with a coherent answer somewhere above the crude monosyllabic responses for which you have become infamous. Keep up the good work; there may yet be a place for you in the family homo erectus. |

Such a SWEET Attitude! At least I don't hide behind a false name and
shrieking faction of what life is all about. After all, I have made a fairly good living in repairing these friggin items for over 30 years and do not appreciate free loaders such as you taking advantage of me or ANY OTHER TECHNICISAN!!! Stated many times before is the fact that you get what you pay for in life. You for shovelling sludge, others for taking the deligence to learn how to actually design and repair the materials others design. Some of us do actually give free advice to those who actually appreciate the effort. However, in your case, well enuf said!! "DarkMatter" wrote in message ...

When is a post not a post? 1) When Dark says it isn't. 2) When Dark replies to someone elses post. 3) When Dark gets caught in his normal positon of bending over a bar with his pants down by making yet another idiotic statement which Dark then says is forged. |

Still laughing JW.....I can picture this fool sitting on the phone
books.....Good one... Hey, I wrote a tune for the little "Turd Burglar"........ Sing this to "The Beverly Hillbillies Theme".. Grab a banjo and sing along DarkMatter! There once was a Tard Boy and his name was DarkMatter.. He wore a rubber helmet and posted round in here.. And then one day he was being pretty rude.. Then the newsgroups told him to "get a life dude"!... Troll that is, skippy whipper, pencil neck geek! The first thing you know he says he's an engineer.. His folks finally said "move away from here". So he loaded up his helmet and his new set of knee pads. And flew to San Diego where he became frustrated.. Rubber helmet, knee pads, ball gag! And now it's time to say goodbye to Tard Boy and his fits. This tube steak parasite will have to finally give it up.. He's whinin' bout top postin' cuz' he "does not have a life"... If he'd drop his little skippy, he just might find a wife.. Shot to the Head! Noose round' the neck! Whatever it takes! You all go away now Tard Boy, ya hear? "JW" wrote in message ...

Have fun getting anywhere stopping me from doing so. You're an angry little boy, aren't you? Did your slag of a mother refuse to let you breast feed, and make you suckle from a unwashed turkey baster instead? Can't say I'd blame her one friggin' bit... I know you have trouble with English, I do just fine with english, dip****. ^ "English" should be capitalized, you momo. Until you can grasp that simple fact, why don't you pull your bottom lip up over the back of your head and suck in, DorkBlather? but the repeated beatings you've been begging for (and receiving, quite enthusiastically) are a good motivational tool for misanthropic microencephalic Future Organ Donors of America such as yourself. You're a ****ing usenet retard, boy. Your posts are repetitive and boring and have absolutely no redeeming value whatsoever, save mocking. In the interest of humanity, I think you should be euthanised. (BTW, Usenet should be capitalized as well, Mr. English major.) But, only if you pay attention to the lessons pounded into you by your moral and intellectual superiors. Something of which you are not. I certainly am as evidenced by this little exchange, and if I had to make this any more obvious to you, I'd be forced to show up at your residence with flash cards and a electric cattle prod. That's damn near everyone who has access to a computer keyboard, making your vetting process simple enough for even you to complete with a low rate of false positives. No. That is a fantasy in your ****ed head. Neither you nor anyone you were ever associated with qualify. At this point, I'm wondering why you even bother stacking up enough phone books to reach your grimy, drool-splattered keyboard, you talentless, annoying little buttspud. Can't you find another group to troll, perhaps in the alt.idiot.* hierarchy, where you'd certainly feel more at home? |

Same old "DarkManure" posts....He says the exact thing to EVERYBODY !!! No
finesse, no creativity, just the usual "DarkBlather".....A true, Usenet Troll. Here is little troll list...I am sure he has this posted in his dingy little room where he routinely swallows his bong water and washes it back with cheap whiskey! Your name, mine and many others are up on the wall with his little drooled up score cards! The new Trolling Point System for Trolls has been approved by the Central Troll Committee for Troll Standards and Procedures. The new TROLL POINT SYSTEM (TPS) will take effect on September 1, 1999. 10 points Killfile: Being Killfiled is the highest honor and the most points a Troll can achieve. It represents complete victory and indicates that the Troll has performed on a MASTER TROLL level. 9 points Complaint to Trolls ISP: While not as good as being killfiled, a complaint to a Trolls ISP indicates that once again the TROLL has struck hard and deep. 8 points Death Threat: Another indication of a Master Troll at Work. The death threat is firm proof that the Troll has cut to the bone and left his victim (the fish) floundering and gasping for air. 7 points Personal Verbal Attack: A personal verbal attack on a Troll in response to a trolling post indicates that the Troll has riled and disturbed the fish in question. 6 points Plea to Ignore Troll: A Plea from a Forum Group member to other group regulars to ignore the Troll in question is a sure sign that the Troll is doing his/her sport with proficiency. 5 points Killfile response: When a poster who has claimed to have KILLFILED a particular Troll, then responds to another Post by the Troll in question, rates a solid 5 points for the Trolls ability to snag a hypocritical fish. 4 points Logical response: A person who responds to a Troll trying to use logic and reason to rebut a Troll is worth 4 points for such stupidity as to think a Troll cares about what they have to say. 3 points 10+ individual responses: When a post by a Troll gets at least 10 responses from 10 different individuals. 2 points Positive response: If a Troll gets a positive response such as ROFLOL: LOL: Great Post, etc. 1 point Any type of response at all.
