Question about Panasonic CT-36HL43 36" TV
What could it be? If i knew what the beep meant then perhaps i could tell which part of the TV isnt working anymore. Very odd, as it suddenly happened when i put it in standby mode today

Sounds like the connections on the CRT Socket or CRT circuit board. Remove back and check connections.
You could also have buildup on the cathodes of the electron gun (internally) to redimie you must have set in operation and viewing video. Tap the neck of the tube gently while watching for the colors to change until they Stabileize, this is best seen whith the color turned off.

the tv tells you there is a technical problem with it.
lots of time this has something to do with the power supply of the tv.
contact a technician to have it fixed.

SOURCE: I have a T28PL1.
First, remote the TV's power cord from the wall, wait for about 5mins, plug it back in then try again. If problem persist, then it means your TV is having a power problem....
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.

Have exactly the same problem. Standby light flashing twice in 1 second then off for 5 seconds but will not switch on. This after switching off on the set following around 1 hour use.
Switched all power to set off for around 30-40 minutes
