you must check the light indicator if how many times does it blink which tell the main problem or the error code of the tv. either the power supply doesn't work normally or the lamp need replacement.

The tv switched off and the lcd light started flashing green


ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have tobuy and try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.4_12_2012_1_20_07_am.jpg
look at the power board inside the set to see if puffed up caps like these that are bad.
A model number (not indicated here) would be helpful.

Tv will shut off and red light will flash 3 times


If its Sony KDF-42WE655 TV that goes to standby and LED blinks 3 times then check Lamp Door that seems not fixed properly.
That happens when lamp replaced in TV.
If its different model number TV, let me know exact model number.

No Power


does the front green led light flash?
unplug the set for 30 min then replug try to turn on. if the light does not flash then i might be a main fuse. Point... main fuse falure ussally means more than just fuse. if the light flashes then you have a shutdown condition. This set processor shuts it down for 1 or 25 different reasons as technicians we have a computer that reads errors much like a cars error codes.

Is your TV still under warranty? This problem seems common on this site with the Panasonic brand. I really can't say what exactly is causing this problem, but it seems like something in the power circuit board is faulty. My advice would be to call Panasonic's Technical Support Hotline and speak to a Technician. It could even be a problem that has warranted a recall of that particular model. The number for Panasonic's Hotline is 1-800-211-7262. Or, you can contact them via e-mail @ www.panasonic.com under "Get Support". Hope this helps...

When i switch my panasonic tx-21md1 television at the power switch all that happens is that the standby light just flashes on and off at approx 1 second intervals even with no leads connected at the rear.


your set is entering protective shutdown. Most likely its a failure in the standby or start up voltages that is allowing a voltage to increase triggering the shutdown circuitry to prevent your set from starting. Do you have any trouble shooting skills?
