Dan, the light blinks 9 times. Does that help any?
I also have a sony triniton, same problem, my set
just sits on standby/timer mode, it is blinking 7 times, no souns and no picture. I did a hard reset and it still didn't work. Can you help me??

Re: Sony TV stuck in stand by mode
In both cases, I think you are either suffering from a failed power supply or the supply is cycling because of a 'downstream' problem that could be in the high voltage circuit.
In each case, the blink count probably would tell you approximately where the problem is located but only a Sony tech will have access to the codes.
After all, we are only mortals.

In standby mode (red led on/after the led stops from blinking), press "Display", "5", Volume (-)", "Power on" on the remote control in sequence, self diagnostic screen will be display, let me know the what is on the screen to diagnose where the fault came from.
That problem comes up when one or both of the convergence IC's are burnt ... it normally has an "STK" number on it screwed onto some large aluminium heatsink ..... however if you venture to change it get back to me ... I'll try to guide you through ....
Generically, the 6 or 7 blinks usually indicate a problem with the horizontal circuit. In order to provide accurate diagnosis and suggested solutions, the exact model number is needed. Please update this with tha number and I will post more details.
The standby light should be blinking in a pattern. Count,pause,count... Please post the count and that will indicate the circuit in which a problem was detected. That will allow me to give you details and possible solutions.
The 6 or 7 blinks usually indicate a problem in the horizontal circuit. Since the TV recovered once, the problem is most likely to be a bad solder connection in that area. If you can solder, resolder any connections on the board that appear grainy or have rings. That may resolve the problem. If not, update this and we'll look elsewhere for defective parts.
The 7 blinks indicate a high voltage shutdown (high voltage exceeded 33,000V). This is usually caused by a defective regulator. Could you please post the exact model number (KVxxx) and I'll look up the part you will likely need?
Yes. The 9 blinks indiate a problem in the power supply area. I need to look up your specific model later today to get you the specific parts. If you are comfortable with soldering and working inside the set, you should be able to repair this yourself.
The four blinks indicate a vertical deflection problem. I would suspect either bad connections on the vertical IC or a defective IC. This IC is a small flat IC with about 9 pins or so and should be marked LA7837 or something similar. Try resoldering the pins first. If that does not resolve the problem, replace the IC.
You may also need to replace some capacitors in the circuit, but try the IC first and keep us updated.
