If possible, see what it takes to open it up enough to maybe at least get a peek at the backlight and see if everything is lit up. Thanks for that AndyRoss, I did think of that, but shouldn't it refuse to come on with six blinks on the led if there is a backlight problem?
I am an electronics engineer with over 35 years experience, what is obvious is that you are incapable of repairing anything without replacing the panel or pcb, I have repaired many LCD tv's by following signals with my scope and replacing SM resistors or transistors and I have even repaired a dead panel by finding a hidden fusable link on it. I have also replaced ball graph array chips with my rework station, on several pcb's, power boards are just Switch mode power supplies and to an engineer who knows what he is doing, they are no problem, so don't be such a smart ass and think you are bette ..
Hi Guys, Strange problem this one, Yes the power saving is off, as is the light sensor, the Backlight and Contrast are at max, the Gama has no effect at all and the picture is almost to dark to view in daylight, but ok in the evening onwards. can't turn the brightness up above about 60% as it just washes the picture out.

Any ideas anyone? [ This message was edited by: wedgehog on ..

Hi Claudio, thank you for that, very kind. But what I meant was, which other models does the service manual with part number 988826504 cover. Most service manuals cover more than one model. Let me explain, I have a friend who is able to get me a sony service manual now and then, and I asked him if he could get me a manual for my KDL-32EX503. He replied that he could only get it if I could find out the Sony document number. Jehill kindly gave me that, but my mate informs me that he can find nothing listed for my model under that number. he suggested that it maybe listed under one of ..
