Could be a fuse or regulator fried. With this type of repair I suggest an experienced tech unless you are comfortable working around electrical voltages some of which can be dangerous.

2003 Sony Trinitron 36" television. Just shut off, light blinkin


The STANDBY light will flash if the television detects an issue within the television. Some of these issues can be resolved simply by following the steps below to reset the television.
If the issue is still unresolved after following all of the troubleshooting steps, Service will be required. Please note the number of times the STANDBY light flashes and relay that information to the service center.
  1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
  2. Unplug the television power cord from the electrical outlet.
  3. Let the television remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
  5. Turn on the television.

It's simply refered to as the power supply- the repair guys will know exactly what you are talking about when you use it. You see the power supply upgrades the power to drive the tube- much in the same way a coil increases the power on your car from 12 volts to what ever it needs to turn the engine. The green light just means that you turned it on, and all the other curicuts are working. Like if your car coil is bad-you can still turn on the lights and radio-but there is not enough power to turn over the engine/turn on the picture tube. I love my 36 incher- mine is 12 years old-and was only in the shop once-and still gives a better picture than the LCDs out there. I'm a member of SMPTE. society of motion picture and television enginers.

Sony 36" Trinitron Problem


Good day.
There may have been some problem in the horiontal transistor. Also, Check for the zener diode that controls the supply going to the flyback. It might got busted due to the sudden supply surge.

Good day.

The spark the you see means that your wall socket is loose. Have it fixed by a qualified technician. With regards to your unit, it has an internal problem. In my experience, the power supply is not dissipating power to the circuitry. The problem is contained in the power supply, have it checked by a technician.

Sony 36" Trinitron


The power supply section is having trouble.
Common possibilities are:
- High-voltage section (flyback transformer) has failed
(happens sooner or later, about 8 years typical))
- CRT tube has failed overloading the supply
- Power surge has popped the power input circuit.
(Fuse, rectifier diodes, turn-on relay etc)
- One of a hundred of electrolytic capacitors has failed short overloading the supply. They dry out with age, are cheap to replace, but hard to find which one it is.
- Or any of many other possibilities.

In short, you need a experianced tech to troubleshoot this.
