Oven LCD display dim and uneven

Re: Oven LCD display dim and uneven

The displays to wear out, they loose emission similar to a crt in a tv. The display is brighter over the heater wires which makes sense. The display tube should be a 100% vacuum but that can also change over time as a bit of air gets in.
You might try someone that deals in used appliances, you might find a used panel or a similar panel with the same vfd.

I solve such problems by soldering panel component

What do you mean you "fixed such problems by soldering panel components"? Did you just re-solder the VFD display ?

Re: Oven LCD display dim and uneven

perhaps check the VFD display solder connections to the main board? if you can inspect them wth a magnifying glass. You might see solder joints that are cracked. reflowing the joints with some 60/40 might help if they are losing conductivity.

I am having the same problem with control board #3116090102. Going to try the cap route and inspection. After reading through the thread, I hope that I have better luck.

Seens that I have to purchase caps in batch quantities. My cap values match those listed in the thread. Good job on making your problem and approach clear and conconcise. The pictures and list are helpful.

Look at the soldering joints on the display pins and if the soldering joints are not shine then remove the solder form each soldering joints and resolder each joint and see if this makes any difference in the display

Also replace all the capacitors on this board as well
