    Have you a voltage meter to check the volts from the board to the av board. the voltages need to be correct.

    I can check, is there a good source that would have the pinout and expected voltages? Thanks for the help guys!

    smasung are usually good at putting the voltages out on the board so look there. they have different power board for the same model so you would need the board number to check the voltages but like i say they usually have it written on the board

    Thanks for the info! After I found the voltage printed on the board and tested, the voltages were slightly off (20%) and I could hear a buzz from that board when I tried to power it on. Part ordered.

It could be a week power board, check the capacitors on the power board and that look like they have a rounded top will need replacing, this is a common fault, over time they just wear out for use, replace with same rating on the capacitors, make sure they are 105c type.

Testimonial: "Okay, I did look and there aren't any signs of a blown capacitor or burnt component on any board. I wasn't sure if the fact that the standby light was on pointed to the main board. Thanks"

    You nailed it. Power board was producing 11v instead of 13v. Replaced the part and it's as good as new. Thanks again!

  1. Turn your TV on.
  2. Press tv on your Sky remote control.
  3. Hold down select and the red button together for about two seconds, until the red light on the Sky remote control blinks twice.
  4. Press tv on your Sky remote control again.
  5. Key in the code 0157. The light on the Sky remote control blinks twice. If the light blinks once only, recheck the code you entered and start again at Step 1.
  6. Press the standby button on your Sky remote control. If your TV switches off, press select. The light on the Sky remote control blinks twice (code stored). If your TV does not switch off, press tv, then press the standby button. Repeat this (press tv, then standby) until your TV turns off, then press select (stores code).

Standby light stays on and the tv will not go on


Please check batteries in remote that seems not working. Sony TV would either turns On or standby light will blinks if TV gets any internal problem.
You question shows standby light stays On that means TV does not receive power on command from remote.
If standby light is blinking in sequence, let me know how many times it is blinking and also intimate exact model number of TV to find out possible solution.
Thanks.

Sony Trinitron Wega Standby blinks & the TV won't turn on


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.
