Check its main rectifier diodes. If any of this is shorted, this type of fault can occur. More to say, when you repair power supply regulator board, you should check all the other components too for damage.

I have a tevion lcd4203 42inch that wont turn on the standby button just flashes


So what is your TV: LG 42LC2D or LCD4203?

I'd check the exact model on the back if I were you.

In LCD TVs this could be caused by either bad power board or bad main board.

In plasma TVs this can be caused by other boards as well.

If it's an LCD the first step is to verify the power board.

if it's a plasma it's usually to start eliminating other boards by disconnecting them from power to see whether and when will the auto-shutting (the blinking LED) disappear.

Probably the easiest thing to do is to send the power board to someone who knows how to test it independantly.

If you want to do that feel free to contact us or just find a local provider.

Tevion 42"plasma power on but


Hello,

You need to check the output voltages of the power supply to see which one goes off. It may be due to short circuits some where,if otherwise, Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

I hope this will help in solving the problem and do take care in handling the problem....

Check if the Pico fuse is blown ? next to the heat sink on the transisitor array with the number 2025.if the fuse is gone than the fuse plus the 2025 transistor must be replaced.
