I own a Sony Bravia KLV 32BX300 for the last 5 years and it had been working great until March 2016 when it developed a problem.


Hi Raymond
Other than Bad Connectors & Intermittent's?

Modern Tv's are digital computers.
They Rely on a clean well regulated power supply.
Any noise on the power supply rails can cause a 1 to become a zero & vise versa. Digital computers handle billions of 1 & 0's

I suspect you have a faulty Switchmode Power Supply Module.
Faulty because the Electrolytic Capacitors have chemicals on their plates and they go sour after a time.
Consequently they Leak or Bulge at the top & even blow the top.

Simple fix is replace the Power Supply Module (if separate PCB)

If your up to using a soldering iron, the following may help
There are no High Voltages like 30KV inside any more.
But there is the AC Mains voltage of 115 or 230 to contend with.
A Multimeter can be of help here.

Good Luck

My Computer Screen is stuck in power save mode. I have disconnected it shut down and rebooted. And still the same. Unable to do anything on computer. Help


Hi Faith
More than likelly the Switch Mode Power Supply board is not powering up. Often caused by bad or leaky electrolytic capacitors.

Nowadays, the switchmode power supply module converts the incoming AC power to the lower DC voltages required by the other circuit boards.
It uses lots of Electrolytic Capacitors to clean up noise in the DC power. But one Electro Cap is used to store a charge for turning on the switch mode power supply. Being Electrolytic they are prone to leaking & bulging so they don't do their job. They won't hold a charge. By pulling the plug and restarting, you have found a way to overcome the problem. But only temporarily. When the Cap goes fully bad, you won't be able to start the TV any more. Suggest you order a switch mode power module for it or take it to a tech who will replace the module. It's usually in a metal shielded small box full of ventilation holes.
I have repaired many switch mode PS but most tech's these days don't bother. They just get a replacement board

If you have the technical ability you could find the faulty part, unsolder it and replace with a new one for $1.50

Otherwise take it to a technician.

Good Luck

My tv Won't turn on by pressing power button in tv,but if I unplug from outlet and turn on tv turns on like nothing happened.why?


Hi Uzziel

The power button is digital these days. That is... it does not have the AC power directly connected to it. Like a normal appliance.
It's a Computer.
Nowadays, the switchmode power supply module converts the incoming AC power to the lower DC voltages required by the other circuit boards.
