Bigbengaz,

The 2SD1880 is the horizontal output transistor. These often fail as the only defective part. Make sure that you use plenty of heatsink compound on the new one when you install it. That should resolve the problem. If the transistor fails again relatively quickly, then the actual problem is likely to be a failing flyback transformer.

Yes you must replace any failed components before proper operation can be restored.

Sony kv27546


older set---may not be worth repairs.

Here is what is common on these:

Problem happens that instantly takes out 2 regulators in the power supply, a protect fuse, the sweep transistor all in one shot.

Usually caused by a bad solder connection in Horizontal circuit.

These parts are easy to check--if one is gone all will be gone.

All parts are soldered in so..........

If a 27 inch set may be better to just replace it.

If someone there is tech savvy I will assist if needed.

SAMSUNG TXH1970... The standby light is on, but when I press the power button nothing happens.


Hello
There is some short circuit in the secondary side of the switched mode power supply section inside the circuit board. Now only the 5VDC is correct, as you see the standby light ON. The short is likely to the horizontal output transtor. Replace it first and see whether it helps you. If not line out put transformer is faulty, and should be replaced with same type and number..If any internal short occurs, the power supply protection system will activate, and shut down all other secondary power supply rails, as a protection to prevent further damage to more components, This is happening in your TV now. OK

Our TV won't turn on when we press the power button it clicks but doesn't turn on the monitor. When we opened the TV set up, we found a little device on the switchboard that makes the click when we hit...


good day sir, hi, as you know it is dangerously working with this type of appliances, you should let the diagnosis to an expert in TV, or else more damage may happen, worst you may get an electric shock.
The problem part MAY be anywhere in the power supply section, a faulty voltage regulator, an open low value resistor, a leaking capacitor, or a defective switching controller IC, this are to be checked thoroughly.

Screen will not turn on, power light flashes red. Nothing happens when power button is pushed will not turn set off.


try checking first your tact switch or your power button, then next look for open fuses or low ohm resistor on secondary part of your power supply then check your horizontal and vertical outputs for shortage and open circuits check also your horizontal drive stage.

Tv won't turn on at all


no remote but tv was working with front power key? unplug from ac outlet and plug back and listen for any type of indication (noise or chirp) that something energizes inside if theres nothing then suspect a power supply problem, main fuse blown, shorted low volt rectifiers other components could be at fault.

Power problem on a RCA big screen TV


Even with the tv turned off, the power supply is still active.It's supplying voltages to the microcontroler, that's why each time you press the power button on remote the tv respond by turning on. First check the power cord to be well connected in the power-bar and if it's ok...well the power supply is defective and due to the high risk of electric shock i suggest you to call a technicien.
P.S. I respond here because I don't know why our chat session got disconected.
