I just got this thing from a friend and I'm usually good at fixing used tv's but when i hit the power button the standby light just blinks untill i turn it back off.....nothing else happens...at all..but it must work or that wouldn't happen..it's like it has a lock on it or something...

Re: Blinking standby light and nothing else...
When Sony TVs detect a problem, they shutdown and present a blink code. The blinking should be a repeated count. Please report that count here as that indicates the circuit in which the problem was detected.

The blinking standby LED usually is an error code - indicating possible overcurrent protection mode. It can be either a short-circuit in the power supply, the HT rail, or the horizontal output transistor(s) could be shorted along with the flyback transformer. Or it could be a combination of all of the above.
Assuming this is a model with a CRT, I doubt it would be the 'bulb' - it would most likely be a circuit failure. Check the flyback transformer, the horizontal transistors and the tuning capacitors in their collector circuit - one may be shot.
Check the power supply and HT thoroughly for shorts and open circuit components - burn marks on the board, dry solder joints etc. Look for obvious things first.
Once you are satisfied that one or more parts have shorted, and you don't wish to replace them yourself, submit the TV to a repair store and insist on a FREE quote - this way, you can then decide if you want to pay that estimate to fix it or not.
Modern tv's have power supplys that shut down on standby when faults appear , often its capacitors in power supply that fail, they usually go like batteries and leak. You can sometimes spot them ( with a trained eye) they swell up .... but not a repair for the novice. capacitors are cheap, so i would not expect a large bill for parts
but time for engineer , uplift , bench repair , delivery . vat etc wow £ 100 or more pete ps (had same fault with friends tv) I fixed it for £ 20.
The blinking standby light is an indicator that an internal safety circuit has kicked in. The light shouldbe blinking a repeated pattern of count/pause/count etc. Can you please post the count here? That will indicate the problem circuit and allow us to provide you with the solution.
I have a Sony SRS BBE Trinitron (WEGA). The last few days when I tried to turn it on using the remote the Red Light would go on but the TV did not turn on. I would have to press the power button again to turn it on.. I tought the remote battery was just low.
Today when I tried to turn it on nothing is happening and the Red Light is blinking 9 times ??? I tried to unplug it and try it again, still does the same thing ???
Hi shelly i have a lot of sonys come into my tv shop. There is a code for blinling problems but it never helps me.But blinking problems two blinks is says power supply problem i usually charge around 120.00 to fix this kind if you would bring it in.
It is very common problem and most service centers can fix this
Standby light is a signal indicating a voltage trouble on your system . It could mean a compoment is defective or a power regulator needs replacement worse is a system IC replacing. you better bring your stuff to a Sony service center and do a check on your TV system.
