Fit perfect super easy to install.

Hi All,

So I put in my new LCD screen and all was working well for a few months. Came in one morning to power up and I heard the coolant pump running. Shut it down and turned back on same. The...

Thanks for the thought, I already put in a new LCD. expensive but it works and now I am making chips again. Thanks for you help.

Hi All,

I have another problem that I can not figure. I am counter sinking three very small screws into a piece of stainless steel. Made a very simple program (see below) but when I go to "Run"...

I got some horizontal lines and some other static. Not sure what the issue was. When I hooked up the old monitor again screen worked for about 5 to 10 seconds then would go blank again. Seems...

Wired video output to Yellow on old TV got something but not usable. Biting bullet buying replacement LCD $800 upgrade.

Put in the resistor, Put in the new transistor, solder down the choke filter and ... The screen came on looked great then back off. Screen is dead. :eek:Very long stream of expletives

The four wires from the edge connector goes to CRT COMP - CRT GND - +12 GND - +12 CRT the VID GND and VID COMP come from somewhere else not that edge connector. I think RCA cable just might work!...

:banana: I just got an email from Ted from Parts and Smarts- He said "R480 on this board is 470 ohm, 5%, ¼ watt." I have that one. Once I get my transistor i will solder all up and see if I can make...

The connector on the board is a 10 edge connector. Then it goes back to the terminal block. Just to be clear do you think that if I take and wire a RCA connector to the two middle wires VID GND and...

Yep, I took the resistor out to make sure it was burnt all the way around. The only color I can make out is the gold which makes me think this is a critical value. I have found other monitors but...

Hi KOC62,

I have not been able to find a service manual. I tested other things on the board and I think the transistor with the big heat sink went bad. It also melted the solder on the choke...

I have looked for a new CRT and board but they range from $800 to $1200+ Just thought I would ask if anyone did a DIY monitor change to an LCD. I know the Delta 20 old is but she is mine and I am...

Hi all again, I see 65 people have looked at my resistor problem thank you. I just thought I would add that you do not have to remove the board it sits just under the CRT. The resistor is right in...

Hi All,

I have a Delta 20 and the monitor went out. I found one of the problem but the resistor at location R480 was so burnt that I can not tell the value. There are many CRT boards so I will put...
