Question about Sony KDS-R50XBR1 50" HDTV
Just got my R50XBR1 back from the shop after replacing power supply, now the picture is fuzzy around images.. Looking at text on screen,can see green on one side and red on the other, colors not aligned together... Now what??
1. Try this - hold the menu button down for 10 seconds. TV should power up; you will have to turn off front panel buttons on menu.
2. You can also try a hard reset: Unplug TV from AC mains and remove all cables from TV. Wait about 30 minutes and replug to AC power and redo the cabling. Switch on the TV and see if it works..
if not please follow these:
1) Main cause of defective will be located on the KD-board
2) Confi rm KD-board is securely seated on the G2-board
3) Replace KD-board
Thats a fairly complex Chassis. Unless youre really good at dissassemble and reassembly of small components, I would suggest a Sony authorized reapir tech do the repair.
Certainly, I can help you. I would recommend going to the following link and getting the service manual so he can see first hand disassembly instructions and testing proceedures. Its only 10.99 and they email it to you shortly after purchase. The manual is a valuable resource as it will have part numbers in case you do need a new KD board. heres the link.
