Egret 3 chassis replacement
Hi
Can someone tell me if a Wei-ya C3129DHSS chassis would work as a replacement for a Wei-ya C3129D01-7 ?

What's the tube number on your Egret3?
That chassis shows as a replacement for Samsung A68QCP891X002

Re: Egret 3 chassis replacement
That's a dual focus chassis (you can tell from the 2 pin socket) single focus there's only one it's the same as the one I have for sale with a Phillips tube.
A single focus chassis won't fit so the replacement needs to be dual focus to fit the tube.

Can someone tell me if a C3129D03 chassis could be used as a replacement for my C3129D01-7 ? Thanks

Re: Egret 3 chassis replacement
I have an M3129D01-7 in My AWSD
dont know if thg C3129D03 is compatible with your E3

Re: Egret 3 chassis replacement
I got this message from Mr. Wei-ya
After our engineer review, C3129D03 CANNOT replace with C3129D01-7 directly,
since there over ten parts difference on main board/CRT board/small board.

Re: Egret 3 chassis replacement
Someone tries to fix my chassis but we need help. Does someone has a schematic of this chassis?
I am in need to get some information about this chassis It works with some prob in the H-deflection.
There is a small auxiliary upright board in the near of the line-out-transformer.
Some connectors at its edge look burnt, but they are really good.
Nearby a resistor (R17?) ist burnt and open circuit, therefore the plastic is melted.
The big brown cap at its side is in spec.
Does any manual exist? Any the value of the resistor may move me forward.

Re: Egret 3 chassis replacement
Maybe you can get a scematic directly from Wei-ya.
Can you see any numbers or a color code on the resistor?
I also don't have such a monitor/chassis but maybe the is someone arround who has one and can identify the values of the bad components. You could make some fotos, too.

Re: Egret 3 chassis replacement
It's the R17 resistor which is burnt and he can't see any colors anymore. Unfortunately he has the chassis so i can't take any pics. I just wrote to Wei-ya. Thanks the help

Re: Egret 3 chassis replacement
no one has a schematic for these and wei ya will not release one
you can use the rodotron 666 schematic as the majority of the chassis is the same
the fact that resistor is cooked may point towards the HOT being short circuit

Re: Egret 3 chassis replacement
I emailed Wei-ya and you won't believe what i got . A schematic for the M3129D01-7. My one is a C3129... but i hope it's similar.
You said that R17 is 47 ohm 2w metal oxide but in both schematics it's 1kOhm?!?

Re: Egret 3 chassis replacement
mine is the original c3129d chassis
perhaps you have the later chassis with the single connector to the 31khz switching pcb

Re: Egret 3 chassis replacement
In my chassis the resistor was pink, but unfortunately it's not possible to see the value on the old picture. Thanks a lot for your help
I just checked the R17 again on the small board and it's 47 / 2W. You are right. On the schematic were 2 R17, so that's why i was confused.
Here's the schematic for a M3129D01-7 M3129D01-72 (C3129D01-72): http://uploaded.net/file/nhj7p81l

Re: Egret 3 chassis replacement
Great getting the schematic!
Not sure where to stick it, but at least it's on the wiki:

Re: Egret 3 chassis replacement
So what was the problem with the chassis. I try to translate what was discovered.
R17 is on a additional board "3119-3" PCB is in serie circuit with C8 and T1 on the lead of D and F
D leads to the base point of the H-deflection of the "Zeilenlinearitätsspule"
F leads to the middle point of the O/W modulation control
Therefore this circuit is placed paralell to the tangens condensator C84
Because of that the resistor can be destroyed if the main lead over the tangens condensator is interrupted
Something like this
So the tangens condensator C84 and the resistor R17 were broken.
