I have this exact same issue; search engine took me here. I have been experiencing this problem for about a year now. When you power on, the RED standby light goes out, the power light turned GREEN, you might hear a small pop sound, then the RED standby light goes back on. YOU HAVE BLOWN A FUSE. My problem is this is occuring much more frequently now and I'm going through fused like crazy. So I'm looking for a long term solution.
To replace the fuse, turn off the standby power switch on the front. Unplug the power cable. Open the back panel. All logic and power modules are on the bottom of the cabinet. Therer is a large power module in the middle. In the middle of this module are 3 fuses. The one that typically blows is the one in the middle. It's a 5 amp fuse, but double check the rating before replacing.
I have a call in with Pioneer for help. Some additional info. Parts can be found at parts.pioneerelectronics.com . The fuse that is blowing is identified on the PCB as FU303. The part number for the Power Assembly is AWV1887 (OLD model) or AWV2011 (New Model). Depending on what Pioneer says, I'll probably replace the Power module; $311.

Sounds like back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electro-medical.blogspot.com/ http://electronicshelponline.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced.
green led means tv powered on and status ok.
Red blinking light almost always means defect, overcurrent or overload.
6 blinks for Sony lcd flat tv means trouble in backlight circuit, or backlight inverter (backlight illumination or lighting makes your tv screen visible).
common problems in the inverter circuit, which drives the backlight, or shorted drivers, or short-circuit transformers or open circuits. You should find the problem in the inverter circuit, or in the power supply board or in the main board.
Also look for bad capacitors (electrolytic caps) which are bulged and swollen on top.
Decoupling plugs from printed circuit boards can help you in finding the problem board by elimination method.
If you power up the set after unplugging certain plugs on f.e. the inverter board , this could result in getting a green power led and concluding that this board is faulty.
My Loewe Aconda 81 HDR TV will not turn on. When I press the power button the green light comes on but the red light stays on with it and after a few seconds the green light goes out and the red light stays on. Any help please.
