Pixelated Readout Hameg 404-2
Hello,
I purchased a Hameg 404-2. It works normally as an analog scope. But what doesn't work is the readout, the display of the numbers and letters on the screen. These are pixelated. I have restored several vintage scopes (Hameg, Tektronix, Leader) but have no experience with this type of scope. Where can I suspect the error, which module is in question? What is the procedure? There is a circuit diagram, but it doesn't really help me. I checked the supply voltages and everything was spot on. Can someone help me? Thank you.

Tektronix DC502 option 1
Hello. This is my first post on the forum. I have a defective meter Tektronix DC502 Frequency Option1. SM fits the DC501. The damage is that it always displays "1111111". Generator 5MHz is operational. 7490 dividers as well. Unless the system is damaged 74LS112 U165. On its output there does not appear, regardless of whether the generator is working or push reset. Can anyone confirm this? Sorry for my English, I use google translate.
MY-64 DMM kapcsolási rajzot keresek, Nem MasTech MY-64!!!
Üdvözlet Mindenkinek!

Keresem (nem MasTech) MY-64-es műszer kapcsolási rajzát.
Fő aktív áramköri elemek:
- 1 x ICL7106
- 2 x LM324 (4-es OPA)
- 1 x TL062 (2-es OPA)
- 1 x 7555 (NE555)
- 3 x SI tranzisztor

Igen, néztem itt a tanyán is az összes MY-64 műszer kapcsolási rajzokat, de azok nem egyeznek meg a kéresettel. Nincs CD4011 (4xNAND kapu) és csak 3 tranzisztor van a műszerbe!

Igen, a Google a barátom, de az eddigi kereséseim mindig a MasTeth MY64  rajzát hozták.

Fotók mellékelve.

Köszönöm!
