socket should be marked CN8023, and this board is called the D board. This is an RA-6 chassis and is a good set. I am wondering why the set
was not repaired. Was it in an authorized Sony repair shop. If not you should find an authorized shop and get this puppy looked at. Good
Luck, and let us know what you had to do to get this TV set working.

Larry Dillon, might you give me a little advice as to what MAY be the problem. I only ask so I have a heads up for when I take it in because the
last guy I took it to tried to tell me that the D board I had didn't even go to my television. Here are the exact symptoms: When plugged in, (1) I
hear 4 clicks about half a second apart (pressing the power button after the initial plugging in also produces the clicks), (2) see the standby
light blink 6 times each iteration, and (3) no signs of ANY video or audio. Thanks a lot.

Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle
IC, IC206. This means that somrthing is holding down the horizontal oscillator and not letting it start up. You could have a short in just
about anything in the horizontal sweep circuit, or the sweep power supply. Have you had this Tv anywhere else then the shop you had ir=t
in? I wonder why they said thats not the right board? I just hope they did not pull a switcher rro on you. i once seen a shop that did that to a
customer.

I have decided to make an attempt to repair the set myself because I know I will be charged as much as possible if I take it to someone in my
hometown and I really do not have money for that, so either I'll be able to fix it or its off to the junk yard. Do you have any hints as to how to
find where a short would have occurred; will a circuit tester do the job? Or can it be visual? Also, might you know what the purpose of this
white substance in the image is; either it came on the board originally or the guy I took it into put it there (possibly a marker for where the
short is?). The first thing I am going to do is replace the sweep power supply though. I really do appreciate the help.

I do not know why that stuff is on the board. it could be silicon? Do you have a service manual or do you know how to read a schematic
diagram?
