I turned on the TV and it popped and went off and will not come back on


Hi.

When that happens you have usually blown the PSU. The power supply is the board connected to the power cord. If there had been a pop sound, power went off, and now TV is completely off, then the PSU has blown.

There is a 6 Amp 125 VAC fuse in the AC section of the PSU, that is the first part to check.After that test the PSU. Sometimes it is even possible to spot a blown capacitor in the PSU board. They look bulged, sometimes burnt and in some case you can even see a leak. Sometimes is instead possible to see a burnt area that is revealing a short, often in the AC section of the PSU. The PSU is located at the back of the TV. Power must be disconnected before removing back panel. Do not touch PSU. Capacitors can store and release heavy discharge even with power cord not connected. There are also 3 small brown fuses located next to the flyback. Those can be tested using a multimeter. Testing must be done by a trained person.

The PSU cannot be easily replaced with a new one. The part is not in stock anymore (part number was 264102), and it is not even easy to find on Ebay. The PSU must be repaired.

Regards.

If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.

1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

When switching on...clicks, but no pic and red light flashing... must reset by switching powerswitch off than on..this went on sporadically for 4yrs..now samething happend accompanied by a loud pop and now...


Hi Pepe.

Only when there is no power at all, no led on, and no sign of life whatsoever, that means that the problem is likely the internal power supply board.


If instead the TV stays in stand-by, with the LED light on and flashing, but does not respond to remote, or to the buttons on the chassis, then the TV is in protect (safe) mode because an internal fault had been detected. In this case the fault is not necessary the PSU. Parts must be tested to find out. The clicking sound is the protection circuit that keeps turning off the PSU to prevent further damage.

If the problem is the PSU, often it is possible to see at a glance that one of the big electrolytic capacitors in PSU board has blown.

General troubleshooting on this article: Why my TV does not start up and remains in... . I do not think it will help in your case.


If that does not work, contact the manufacturer at the number listed on the owners manual to get the TV repaired by a licensed technician.
Pioneer covers the PSU or other parts even out of warranty only when a determined factory defect concerning that model and year had been reported by a number of technicians.

I have a 30 inch prima/arrow lcd tv which powers up but doesnt remain on for longer than 20 seconds


The tv is probably pulling too much power and so shuts off. Does it have picture and audio before turning off? Are there any blinking lights or anything after it turns off? Unless I get a blinking code or anything, a person with electrical experience is going to have to narrow down the problem since the tv shuts off to protect itself. Could be the power supply or a number of other things. One quick thing to try is to plug the tv into a surge protector or if it is in one, plug it directly into the wall and see if that changes the time it takes to turn back off.

Dead psu


Apply a new PSU, the question is is it worth it to you? A psu is rather expensive to replace I would not try repairing it if I were you.
