| 126142 | 2003-03-07 03:57:00 | Billy T, I thought that's what this site was about, giving advice on fixing things. I know I'm not qualified for this problem but I'm sure not many PressF1'ers are qualified for most advice given. I did state BE CAREFUL! in my post. Also I have done probably about 50 monitors with that sort of problem and it's a piece of p##s, any turkey could do it. Just got to be careful what you touch. I personally won't touch anything inside a monitor expect the end of a screwdriver to the dials. | CYaBro (73) | ||
| 126143 | 2003-03-07 08:56:00 | Fine Cy, but firstly, if you are twiddling the wrong controls and you are working for paying clients it could come back to bite you. Secondly, assuming that you are not a licenced electrical worker with current Practising Licence, it is illegal to undertake that work for reward as you are exposing live conductors and do not have the skills (or probably the equipment either) to ensure that the outcome is safe. Of course if you can adjust the focus from outside the cabinet that is OK. I'm not getting smart with you here, but there are laws the stipulate testing requirements and they were updated and reinforced as of Jan 1st 2003. Just be sure that you are not digging a hole for yourself. I know that E.ric posted recently to say monitors don't have to be tested, but I can assure you there is no such exemption under the Electricity Act, Regulations or the Standard (AS/NZS3000:2000). There are financial risks as well. If you stuff a monitor and the customer takes you to the Disputes Tribunal via the Consumer Guarantees Act, you will have to show that you acted with reasonable care and skill. First stop is your training and qualifications to do that work, come up short and they will empty your wallet. Cheers Billy 8-{) :| |

| 126145 | 2003-03-07 21:28:00 | Near enough E.ric, do you drink Speights but? Thank you for taking the time to add the Chequerboard, it is just great and I've used it a couple of times already. Now, if I was really cheeky :p I'd ask for one more refinement and you would have provided the perfect on-line monitor testing package. What is finally needed is a plain white crosshatch based in the same square sizes as your chequerboard. The present crosshatch/linearity pattern white/purple mix makes colour fringing due to convergence or focus problems hard to pick up in the corners. Maybe you could just make it all white? You have made a really useful contribution to the F1 community with that site. hhh () () () () () () () () I think I'll write a new FAQ about how to use each of the test patterns you have provided. They are just great and can help a lot of users sort out what is going on with their monitor. Is it the sort of code that could be made into a stand alone .exe download? I'm sure somebody would host it (IDG even?) if you ever have to pull it from your site. Thanks again, Cheers Billy 8-{) :) |

| 126146 | 2003-03-08 02:05:00 | Hi Billy T While I quickly made the test pattern I have become undecided on the instructions, and to be honest would of been there long ago but for . . . . . . Like there are a few problems why the focus could go out of adjustment, the high voltage disc capacitor on the CRT (Cathode Ray Tube) board, the CRT socket gone corroded, or just the FBT (Flyback transformer) the FBT could also have a fault that needs the focus to be adjusted as the monitor warms up and other times from day to day, The next story came from the Service Industry Email group The funny thing is "They made the problem" by using "Labor" as the changeable time on the customer bill, While they have ignored to replace the word "labor" that would show the customer that there is something that needs more than just labor to fix their appliance, for example, test equipment (that could cost in the order of about well a good $5000) , training (3 or more years at night school) , and some times circuit diagrams or with service manuals, So when the customer see "labor" on their bill, they think they could make a cheaper repair by using their own labor, and what a mess up, using tin foil around fuses (making a fuse useless), rewiring mains plugs, but getting the mains wires anticlockwise and putting Phase onto the metal chassis of the television, even more fatal stupid things like joining EHT cables going to the picture tube . -------------------------------------- -----Original Message----- Sent: Friday, 7 March 2003 10:50 a . m . Subject: The things customers do to try and keep their TVS going . . . Ye Gods . . This'll make you laugh (or cringe) . . . . . . . . . . . A Goldstar CF29C76 came in yesterday, customer said "Dead-No Go" OK fair enough . . . . Put the set on the bench this morning, powered it up, could hear arcing noises inside . . Quick switch it off . . . Removed back, pulled the board out and turned it over . . . and found a bloody huge screwdriver jammed between the board and the plastic frame in the power supply area!! The supply area was riddled with dry joints and the customer had jammed it in there to put pressure on the board to make the joints touch and how the hell it didn't short the p/supply out and cause a major blow up is beyond me! The screwdriver's shaft was literally touching across pins of the transformer/ ICs/mains the lot! . . . In all my years of servicing, this has the got to be the worst thing I've seen! Some people . Set is now going ok after a good solder up . I don't know about anyone else , but we seem to getting a lot more of this, customers getting into their TVs etc and fiddling around . . Had another good one the other day . . customer bought in a Pioneer midi system (seperates with straps between units) saying water had gone thru it . . . . No evidence of water damage, but some twat had flicked the voltage selectors on the back to 120V . . well u know the rest . . . fireworks . . . Have a good Friday . . Cheers Glen -------------------------------------- You might ask why did I post a reply to of the above story to F1 and not the Email group, well there is one person in the group that can not read Emails, he hardly ever comes up with a original posting, but often replies to just about every other posting, I am very surprised he does not give technical advise on this web site, unless there is someone's name in every thread to F1 . My final comments the brown goods service industry like sitting in there own poo . From Eric |

| 126147 | 2003-03-08 03:52:00 | Hmmmm....... I wasn't thinking of going very deeply into technical causes of various faults because most F1ers couldn't fix complex technical faults, they just want to get a handle on what's wrong, while those who can fix them don't need our advice anyway. What do you think about the FAQ on how to use each test pattern and what to look for? Cheers Billy 8-{) |

As for the convergence pattern the idea is on all monitors, TV's with in-line guns (not many delta electron guns around) you converge the red-blue first for magenta, magenta-green for white, That's why there are magenta lines & white lines . otherwise you have short the signal to ground, and that gets a bit messy, since at lot of TV's and all monitors don't have switchs to turn off red-green-blue electron guns As for the yellow diagnal one, well that just needs to be straight I used it the other day to ajust linearity .

| 126149 | 2003-03-08 22:37:00 | Keep those colours then E . ric, because they are useful to techos who might need to do those adjustements, but add a plain white crosshatch if you feel inclined for the benefit of non-technical people who just want to know what is going on with their monitor . It would round out a really useful feature of your site and I know of no other that offers as much on-line help for monitor settings . Cheers Billy 8-{) |
