Question about Sony MHC-GS300AV CD Shelf System

Display not working.

Hi all. I have had this hifi for around 3 years, went to turn it on the other day and the display isn't working. I checked the manual and noticed that the display has three cyclinic modes display, time and off so i checked all three modes and none show anything on the display. I then reset the unit as per the manual by unplugging, replugging and holding stop, clear and display. I am an electrical engineering student so i should be ok to fix the unit i was hoping for some insight into the problem and if anyone else has had a similar issue. Thanks in advance

This Problem needs an expert Technician: Your problem is due to a missing Voltage around -30 volts that supplies the screen Processor. It could be an open low value resistor or defective switching transistor. Good Luck Toufic Malek

Display went dark/black- symptoms point to T-con board but after 20 minutes, display lit up for 2 minutes then went dark again. Same thing happened again after next 20. After 60, display stayed on

Hi there,

I was a Samsung tech for 3 years, and T-cons are a common problem. But it sounds like a loose wire to the T-con, I have came across the same issue in the field. I would break it apart and look for a loose connection.

Thanks,
Jason

I have a whirlpool built in oven. Model RBD275PDQ8. The display (control panel) went blank 2 months ago. I reset the breaker, nothing. Pushed buttons, it just beeps. 3 days later I pushed the upper oven...

it's the control panel behind that touchpad item. and it's not too difficult, just time consuming. My recommend is to grab a service manual online(usually around 20.00) which will provide good step by step,and also parts list.

spares? well, that's a good question. Until you have that part number, and the best way is to eyeball the one that's in side your unit(no offense to the printers, but mistakes can happen with manuals).

then you'll find out what it's like to be truly handy, eh?
