Hi . . I had a similar problem with this set, the fault turned out to simply be a faulty fuse on the power supply board . . The fuse is a T5A and powers the standby output from this board . . It had not blown but had a dry jointed lead at one end causing the fuse to measure several ohms. This in turn drops the voltage to the standby output and would cause a dim standby light, or in my case no light at all ! . . Replacing this fuse with the same type may be all that is required . . This fault appears to me to be a manufacturing problem, and should really be addressed by Goodmans. . . Good Luck ! |

I took it to the repair shop but they told me they cannot get a New board thats needed to power up the set. Can anyone please help the set is almost new but I dont have any Guarantee.. Ideas, drawings, part numbers and where to obtain them would be great. Many thanks in advance |

| Thanks Mad Professor! Just took out the parts to test them but it seems that one of the 20N60C3 is giving a low reading but functions. One 11N80C3 is dead short and another does not functin properly. The diode seems fine. I had a hunt around in the area but can't find any more faults. One strange thing is that by each mosfet, there is a place for a thru hole diode but no component in there? Maybe it is supposed to be like this or the factory forgot to put them in? I will replace these parts along with the resistors and report back. Thanks |

| Once I replaced all 5 of the parts listed in post #1 the unit now works again. The only problem is that i still get the multicoloured pixels when theres fast movement to you are in the menu's, I can live with it. I just don't have the time to hunt for the problem. |

| @MAD PROFESSOR Did replacing these dead parts work? I am working on a GTV42P4 plasma with LG V6 parts. I found a problem with the goodmans psu (3501Q00055A) which is a similar pcb, dead with the EXACT observations in your first post. Two blown resistors and short across the rectifier (exactly the same part numbers) ect. I dont know weather to get a replacement board or replacement parts (both expensive). So If you could tell me if this is a good fix, it would be GREATLY appreciated! Thanks  |

| Also many thanks "MAD PROFESSOR" for report. (+ world community) I am trying to fix a unit with R102 & R103 with trouble. (PCB is burnt under, one resistor cutted) Here in france I have collected with mine 3 examples. I will report soon. |

| Thanks for the info! I'm currently troubleshooting a similiar chassis on the component level and find your posts very helpful as I'm unable to locate schematics for this model. Old Bassid is the one who needs to quit wasting posters' time with useless opinions. Thanks again, Mad Professor! | |
