Sony PFM-42X1 42" Plasma Monitor - Menu comes up as white lines

[Jeremy112]

Hello everyone,

I have a Sony PFM-42X1 42" Plasma monitor that has an interesting issue. When you power it up it illuminates as normal, but when you select the menu, it shows up as white bars about 1/2 an inch wide and spaced apart about 3/8ths of an inch.

It displays like this from the left to about 2/3rds of the screen, the last 3rd on the right stays black.

What would be the cause of this? Any help appreciated. I have a working one of these monitors and it has a nice image. It would be great to get the 2nd one going.

What does a source/image do?

Hello again Tom,

The plasma does display the source, but it looks as bad as the menu. I took a photo to show what it looks like.

Also, I would like to add that the screen is pulsing bright dark bright dark etc... like a heart beat. Below is the photo of what it does.

Thanks

Looks like bad buffers & bad ER IPM on Y-sus. Will be expensive to fix.

Thanks for the reply Tom,

I did notice that there were several surface mount capacitors that are used throughout this monitor that are doming, they aren't flat on the top, and the Y SUS looks to have a set of 4 large capacitors doming as well.

Would replacing them have any effect?

They are unlikely to be the fault - some types of capacitors can look bulged without actually being at fault. The symptoms shown match that of bad buffers and ER IPMs.

So the monitor is probably not worth repairing I'm assuming. It was worth a try, I didn't pay anything for the pair so to get one whole one is good enough. Two would have been better though

Thanks again Tom!
