Post by thread:[OT]: Monitor repairs ?

I have a 19" LG 995SU monitor in front of me here and it has just started to go fuzzy in spots. And these spots move around! It is out of warranty at this stage, the retailer just wants to replace it - i.e. buy a new one, and there are no repair services for this unit within easy reach. (I'd have to export to the UK for service!) I did a websearch but came up with little info re this unit. Does anyone know of a site with fault/repair info for monitors. Any pointers at all would be appreciated. Slan John -- http://www.piclist.com hint: To leave the PICList spam_OUTpiclist-unsubscribe-requestTakeThisOuTmitvma.mit.edu

It sounds like the shadow mask inside the tube is warping. The real fix is to replace the tube. However if you turn down the brightness you may reduce the power and mask heating so the warping is no longer a problem. At least it is an easy thing to try. Sherpa Doug > {Original Message removed}

Hi Andre and others, I also have a problem with a Panasonic Panasync S17. I've changed the flyback transformer and now I can not get the width and pincushion adjust right. Someone told me I would need a special software from Panasonic to adjust it, I've been in contact with Panasonic but they were of no help. where can I get this software?

Hi John, I can't help with your monitor problem, but I just realized now after seeing this message several times that you used the Irish word "Slan" (for "goodbye" or I think more literally derived from the word for health).

Octavio, The only software I can think of is the driver Which most likely you do not even need it because Inside of your monitor there is a EEPROM contains Driver information when you plug it in your windows will Detect and install it for you. Have you Played with buttons on front panel ? I repaired lots of monitors before you shouldn't have problem like this unless some one played with it. Andre Abelian {Original Message removed}

I used to work on Apple monitors a lot, mostly OEMed by Panasonic and Sony. There was special elaborate software that communicated with the monitor and was used to adjust the bright, sub-bright, geometry, etc. If you replaced the main controller board in some of those monitors, you had to make sure that you downloaded and backed up the monitor's configuration so that you could re-upload it onto the new board and get the settings for the individual tube, yoke, and flyback right - otherwise it was very very difficult to adjust without signal generators and other special tools. It wouldn't suprise me if there was special software. Lucas > {Original Message removed}

Thank you for your answer Andre. I've tried with the buttons but I can not get to adjust it right. I talked to Panasonic people and they said they have a software to make some internal calibrations. They said to call their facilities at Porto Rico and try to talk to someone, but as you can see it's a little vague. Or maybe there are a special "service mode" accessed by a secret combination of buttons...
