Dear all,
I have bought a TDS784D at Ebay some time ago and had no time to test it.
When I finally had time to turn it on, I realized that the display is very faint and the image is out of focus.
The intensity adjustment available on the menu is already at 100%.
I found a very brief adjustment instruction in the service manual and I fumbled on the pots ( after taking a long time to find them) but they seem to be arranged in a different order than the one described on the manual.
There is a list of the appropriate voltages to the display module on the display troubleshooting section and all of them are ok.
I found one person on Ebay selling a new display module and he mentions that there is a time consuming adjustment procedure for this module, but I could not find it anywhere.
I have uploaded one photo of the menu screen to show how out of focus the display is (the file is TDS784D dim display).
My questions are:
1 - Where can I find a detailed adjustment procedure for the display module?
2 - Is there a way to check if the problem is the CRT being "exausted"?
3 - There is a company offering the NewScope-T1 Color LCD replacement Kit as a replacement. is this a good alternate in case I need to replace the CRT?
