so ive been having troubles with the geometry of my tv.. the usual kinda thing..
i sent it off to be sorted out 9as it was still under warranty) but of course they've sent it back better but not exactly right... i remember tv's used to have hidden knobs inside and you could adjust the position of the picture if you took the cover of the back and fiddled.. so i thought i'd try it..
turns out there are two such knobs.. one says FOCUS (i can figure that one out)
the other says SCREEN.. anyone got any ideas what might happen if i twist it?

i dont wanna twist it and mess something up i cant fix.. i dont think the LG people would take it away and fix it for me if i did that.. i figure taking the cover off and fiddling is against the warranty rules..

As well as being highly dangerous. TV's carry a hefty electrical charge in them.....
There should be some kind of service menu to allow you to adjust the geometry. Do a search of the Hardware forum, or Google.
DO NOT ADJUST THEM. They control the voltage that controls the scanning coils on the back of the tube. You stand a very good chance of permenantly damaging the TV, the tube or yourself!!!

good thing i left it and put it back together then!
i tried finding out how to get into the service menu.. but nobody seems to know.. my only new lead is that GOLDSTAR own LG.. so i might be able to figure it by searching for goldstar instead..

High voltage can stay in the set for hours, possibly days, after the set has been unplugged.
:nono:
but glad to hear that the back has been replaced. :)

if you can find anything out can you please post it here, I have an LG RI-32CZ10RX Widescreen and the geometry is slightly off in the left corner, I am not so bothered that I would have it sent back or to be fixed but if I could do it myself for free it would be worthwhile.
I shall do the same :)
btw what model do you have?

Goldstar don't own LG they are the same. LG stands for Lucky Goldstar.

nope.. i found a way to access a Goldstar TV on a US based site but it doesnt seemt to work on the LG set... its very annoying... i dont see how we could ever find this info out unless we started working in an LG repair centre!
Thinkin of getting a lg ri32cz10rx is it a decent tv or is it just cheap rubbish. Do they all have this geometry problem, o'h can someone tell me what geometry on atv is????

id say spend a little more an get an actual flat screen tv.. these arent bad but if i could go back.. id save up a little more cash and get something a bit better (tv's are getting cheaper all the time too!)
I wouldn't say it was cheap rubbish, it certainly does the job, it depends on what your being asked to pay i guess. I paid about £350 delivered iirc after spotting it on the bargain forums and for my 1st 32 inc widescreen TV I don't think that's bad at all. Not all sets were affected by geometry problems or it was only the true Home Cinema :dork: s that noticed as most people were very happy at the time. Shame you can't see the thread now, it was culled when they archived a lot of stuff earlier this year I think. If it was really important to you I could take a picture of what the "problem" is and you can decicde how major it is for you.
Sure it's not a true flat screen but I think for that price it's great and I have never looked back, when purchase time comes around again of course I will get something better but for now I am a very happy chappy :)
Sun, if you wouldn't mind i would like to see the picture of the problem as i am on the verge of buying very soon...
cheers
now then, been enjoying my quarter century this weekend so had no time for picture taking but I should do tonite.
Cheers
heres three examples for you, It is only noticable when watching genuine widescreen or as I have discovered this evening with something like a digibox menu where you have a visible frame running paralell with the top of the TV. Full screen and all other aspect ratios are fine (either that or completely unnoticable).

Personally I think it looks worse on these photos than it is.
Like I said previously, I think you decision s hould be based on price, if it's not costing the earth you will get a great TV and possibly one without geometry problems, they weren't all like this.

my geometry issues with the LG 28" set werent the same at all.. so i think its just luck of the draw..
I bought the same 32". I certainly suffer from geometry problems, but more on 4:3 than 16:9. On 4:3 the edges roll off much quicker than the middle. I think its a linearity problem, but it is a while since I lined up any monitors (used to do it for a living doing videowalls). I would love to find the setup method.
