Replacing my monitor

[Marky_1979]

If I want to replace my current monitor what should I buy I found this on the back of the monitor.

[grantspain]

thats a good monitor why do you want to replace it?i would be interested in buying the chassis or do you want to change the entire monitor

[Marky_1979]

The monitor has some scratches on the screen which are visible when playing I am going to try and remove them some how and failing that will get another one.

hantarex(based at sydenham hill,london) sometimes have tubes on special offer,maybe you should check out their website(www.hantarex.co.uk) or give them a call as i believe the polo2 are an excellent monitor

[Marky_1979]

so can i just buy a new screen? and attach all the same boards and bits. Sorry I know nothing of monitor I was under the impression they were like tvs if you get a scrathed screen you buy a new unit

[grantspain]

what size tube do you need?i have a list of compatible tubes although you may need to change a resitor

[Marky_1979]

To be honest I really dont know will it be displayed on the monitor somewhere. I take it that I can use any one of a list of monitors and the main bit is this polo 2 board that does all the work. Sorry if this seems a stupid question but Im still learning about arcade monitors.

on the tube itself you will find a label with something like A66EAK552X11,that tells you exactly the tube size and type.
if swapping a tube is beyond your means i know people in the u.k that can do it for you for a price,but i must say getting a new tube and having it installed is gonna be a lot less than buying a complete new monitor.
yes you are correct about the chassis(polo2) being able to fit to many different tubes.
the thing is for me its piece of pxxx doing this job but for a novice its not so easy and there are high voltages present in a tv tube.
i think the most logical way forward for you  is to get a direct replacement tube(delivered direct) and have a pro come and fit it

[Marky_1979]

I think that a repacement tube is a good idea do you know what kinda price im looking at for thr tube without any professional instalation.

[grantspain]

hantarex have a 28 inch tube that will fit your chassis for 50 quid on special(A66EAS13X01)

[Marky_1979]

I found this on the back of my monitor Sambers Italia S.p.A Serial Number 2070 A59EAK552X11 means nothing to me but for you guys maybe makes sense?

[grantspain]

that means you have phillips 25 inch tube which can be replaced by a videocolor tube of code nos.A59ECY13X01 and A59EAS13X01,you should contact hantarex to see if they have these tubes kicking around.
if you use the videocolor tubes you would need to change resistor r35 from 2r7 to 1r on the neck card(easy job)

[Marky_1979]

So for a straight forward hassle free swop what would you recommend I get. I take it these are compatible with the arcade vga that ultimarc sell.

[grantspain]

nothing is ever a hassle free swap,if you swap a tube you need to swap over the yoke/degauss/earth strap but its a lot less money than buying a complete new monitor-basically you would have remove the entire monitor and its mounting frame from your cab then disconnect the chassis from the tube including discharging the anode then you would unbolt the tube from the frame and swap everything onto the new tube and then reassemble.it would take me about one hour in total
yes a polo2 is usable with an arcade card
really everything depends on your experience on how much this is gonna cost you,how much experience do you have?

[Marky_1979]

I have no experience at all but am finding these forums very helpfull especially with experts like yourself helping me out. I think that I will contact that company regarding a new tube so what would I need to order so I dont have to change resistors. Are you from the UK Grant

[grantspain]

i am from the u.k but i now live and work in spain.
hantarex are a helpful company maybe if they have the correct tube you could take the enite monitor to them and they could swap it for a small charge,they are in south london,where are you?
to be honest if you're worried about swapping a resistor then i would not even try to swap a tube

[Marky_1979]

I live in Derby Grant im sure I could swop the monitors and change resistors its just a matter of having the information and guidance to do it. As I say this is all very new to me and dont even know which bit is which iv looked over the faq and am slowly but surely getting there.

[grantspain]

see how you get on with hantarex first and we will take it from there

[Marky_1979]

Cheers Grant ill get on to them asap do i just need to quote my current pollo2 board and monitor reference? or ask for anything spacific

[grantspain]

all you need to quote is chassis type-polo2 25/28 15k/25k and tube type-A59EAK553X11,talk to someone in technical spares dept. and ask them for the same tube if possible but if not just a compatible tube,just get a price first.
that resistor is really easy to change because its on the neck card

[Marky_1979]

Cheers Grant apreciate the expert advice. If I ever wanted to get a touch screen would that also be compatible with this set up or is that a whole new area of tecnicality?

[grantspain]

i have worked on a lot of touch screen stuff,its been the microtouch system-you would need the screen itself that tapes to the tube,a microtouch controller and the microtouch drivers and a bloody good earth.there may be another way of doing this but this is the way i know.
microtouch parts are available from suzo in the u.k

[Marky_1979]

Long time no speak Grant iv finally got around to sorting my replacement monitor out a new tube is costing me £220 that's with delivery its a polo 2 I'm told so as regards the change over process any advice? I would hire an expert but cant find one in Derby area everyone I asked looked at me like I was asking the impossible. Cheers - Marky

[grantspain]

bloody hell,that is a long time
so you bought a tube only?
and you need to place the old chassis onto the new tube?

[Marky_1979]

yes mate just bought a tube as a whole new unit worked out at nearly £500 so I will use my old polo 2 board so yes its a matter of swoping tubes I know that an expert is best but with lack of that do you think that a complete noob could do this ? I don't want to spend my money on a tube and wreck it. Cheers - Marky
