When we plug the tv int all we get is a red light that says standby we do not get a picture and if we push the power/ standby button the red light goes off and we have to unplug it from the power source and then plug it back in to get the standby red light to come back on .... How do I get it out of standby mode it worked fine and we just moved it to a different location and it was unplugged for about 2 days now we ca t get itbto come back on...please help,,,,, thanks

Most often, this symptom is a result of a failing POWER SUPPLY CIRCUIT but a faulty MAIN BOARD can certainly cause very similar symptoms. Unfortunately, without a donor TV to swap parts with or a dedicated test rig, it can be very difficult to differentiate between these problems.

One quick way to test this is to remove the rear access panel on the TV and replace the power supply circuit board with a new one, since this is the most often the source of the trouble.

You can usually find replacement supply circuit boards online by searching for your TV's model number. Here is a link to the SHOPJIMMY.COM parts supplier website where you can find all the available replacement circuit boards for your model of TV along with their prices:

Here is a direct link to a replacement POWER SUPPLY BOARD for your TV which runs for about $103 US plus shipping, although SHOPJIMMY appears to be currently out of stock of that one:

Here is a link to that power supply board currently available on EBay for about $90 US:

The repair / replacement procedure is not extremely difficult if you have some basic electrical safety knowledge and some basic electronics / mechanical repair skills.

You will need to unplug the power cord from the unit, lay the TV screen side down on something soft and flat like a bed if necessary, and then remove the rear access panel or the entire rear cover as required in order to access the circuit boards inside.

When you remove the rear cover and access the circuit boards inside, just check the part number that is printed right on your circuit boards and confirm that they exactly match the ones provided in the Ebay listings. Also make sure that any part you order is labelled "TESTED WORKING" in the condition description. Any part with a condition description of "AS IS" is probably faulty itself as well.

Then unclip and remove the various electrical wire connectors leading to the power supply circuit board. Then remove the screws securing the circuit board to the TV frame and then remove the power supply circuit board. Be sure to avoid touching any large capacitors on the circuit board which can retain a nasty charge even after the unit is unplugged.

Then just screw in the new circuit board and connect all the wire bundles to their appropriate connectors on the new circuit board and then replace the rear cover. Then plug in the power cord and test.

Hello,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.

All these can be checked on the power supply board.

But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.
