| Not really. If you unplu boards and it comes on, you can narrow it down to that board. Seems you've unplugged all the boards and the set hasn't stayed on. | |

| minnie, That sounds as bad as it gets. Makes sense though. Is there away to test the panel to verify what you suspect? Thanks for the help, Steve |

| I's suspect the Y sustain took out the power supply. My guess is a bad panel took out the Y sustain. I think you're looking at a bad panel. BN96-03290A subs to a BN96-03290 list about $600 plus a $500 core. | |

| minnie, I found another fuse blown. Thought I had check everything. I waited to reply until I got new fuses. It's the 5A fuse on the PS board. I inserted a new fuse and and plugged it in the fuse blew immediately. I had the plug feeding the X&Y boards unplugged. It looks like the PS board has a short somewhere. The board is pretty busy and checking diodes while in place is not reliable. DO you have any suggestion? Thanks Steve |

| Have you disconnected the Y and X and no change? Have you disconnected the bottom buffer boards or the Y sustain driver boards? | |

| Minnie, I unplugged the Y sustain board and the same thing occured. Note: there is a ribbon cable connected to the Y-Main board that I haven't tried to disconnect. Can't really tell how it snaps in, didn't want to break it. If I need to disconnect it I'll figure it out. The main power plug is disconnected though. A little more specifics as to what is happening not posted above. I mentioned a board I can't see straight on. I can tell that there are two green LEDs that light when the relay energizes(I hear the click). About 4 seconds latter a third green LED flashes 4 times and all LEDs go out along with the relay de-energizing. 2 seconds later the relay energizes the LEDs come back on and the cycle starts over. Thanks for your interest and help. Steve |

|
| Model: HP-S5033, Model Code: HPS5033X/XAA, Type: CD50P7 Initial problem: loss picture sound was ok. I found a 6.3A fuse blown (F5002) on the 50'HD W1 Y-MAIN (Model No on board, not sure if that is really a hyphen) PCB Code: LJ41-04516A. I replaced the fuse. Now the Stand-by turns on and off. (relay pulls in then releases) All caps look good. The power supply board is a Model PSPF501A01A. I disconnected a harness that goes to another board which connects to the X-Main & Y-Main. PSB relay continues to cycle on & off. There's another board behind the board where all the Ant. cable, HDMI, component cables connect (Model Porsche/Cadillac, that's what it says) that is connected to the PSU board with led that flash on and off with the relay cycle. When I disconnect this board from the PSU, I hear the relay click only once and the led on the power button, on the front of the tv, flashes 4 times and goes out. Note: this other board also connects to the X-Main & Y-Main boards through ribbon cables (not sure how to disconnect these). I sure hope someone can help me out here. Steve |
