Hey,
I posted the following on this thread in Augs and got no response. I would appreciate any help at all...even if it a point in the direction of another forum.
"Hi everyone,
I just signed up for this board. 3 days ago my MAG 32in lcd tv distorted & the lcd shut off. The sound was still on. Now, when I turn it on, it shows the loading screen for a second (with a deeper black bar in the center) and shuts off. The sounds still plays. I am thinking it is a power issue. I have the same power board as this one (I believe this is the one this topic is about) **broken link removed**
I would love to know what I need to do to get this up and running again. I can post pictures of the board if need be. I noticed a lot of cold solder as well as evidence of resoldering/work by hand previously. I would be greatly in your debt if any of you can help me. I am dying without TV!"
jomede - It's a deal. email me at jdonovan19@bresnan.net and we can work out the details.
RosaCar - By what yours is doing I don't think it is the power supply. It could be be but I've never seen that power supply (i have the S0804-0901 or yellow ps). It is used in the early versions of the Polariod FLMs. They are a bit more complicated (they have more outputs and feedbacks). You should start by checking all the output on the two White connectors on the right. use a digital meter and reference everything to ground (GND or the metal case of the tv). I suspect they are all good and if they are then the problem will most likely be on the A/D board or the inverter (the inverter is not in the control box, you have to take the rest of the back off the tv to get to the inverter).
RosaCar - I misread your post. It could be your power supply. take a detailed picture of the power supply (including the bottom solder joints) and post the picture. I'll take a look.

I have this same Polaroid no signs of power. I have change the caps the zener diode and even have a whole other power supply. Still nothing no power. This TV has become my lifes mission to fix at this point.
What is the control box .. ? Inside the metal cover is the PS and two other boards. I think one has a coaxial cable going into it ... Is one of these the control box ?

It's really odd that another power supply didn't work. Did you replace the basics first..power cord & fuse? Sorry, don't mean to imply you don't know what you are doing-you sound like you have tried quite a bit already.
No I checked the fuse but I have not replaced the cord . Don't worry about implying anything I don't know what I'm doing. I'm fairly mechanical just not sure. I did check for voltage with the cord plugged in and it has it.
Well i wanted to replace the diode, resistor and the zener but i sont know what voltade i need to buy. i have the 200-POO-MLT666A-AH ( same as the ones karyoker changed)
Sounds like these power supply boards are junk. I'd just replace the thing but they seem to be hard to find. I have the TC18607A1 (200-P00-MLT666A-AH but it's in the Element FLX-3210 TV. Same problem as most of you. No Power, no standby light, no nothing! I have AC input but no DC voltages at any of the output connectors. It sounds like you've all been working on this for the better part of a year. Not worth it for such a cheap TV but if any of you have resolved the issue and could show me a shortcut, I'll give it a whirl. If not, have any of you found one of these at a reasonable price?
I have the early power supply Polaroid FLM-323 (yellow board) and have traced out all of the voltages and found the low side of IC 2 is zero. if you test the low side of IC 1,3,4 you should get voltages reflecting connector CN 3. I think because the output of IC 2 is connected to Connector CN 2 it should be 24 volts. I cannot find a replacement part NEC2561 can any one help. THANKS
Ok...I have changed the power suppy. Tv powers up. Had no picture so I put in a used Main Board. Tv then had a tye dyed look to it. I then changed the T-conn board on the back of the LCD Screen behind the control box. Got a good picture except for the 6 wide spot where there is no red color. I then ordered a new main board and swapped it out. Thinking the main board I got was bad I RMA'd it and got another only to have the same spot with no color. I do not know where to go from here. I am into this tv for 175.00 (repair parts) and dont know if it is worth spending another penny on. Anyone had a similar looking screen that was able to be fixed? If so what part did you change. I have checked all of my connections by wiggling while the tv is powered on and it makes no difference to the bad spot on the screen. Note: When the tv powers on and flashes the polaroid logo the screen is perfect. Pictures included
That's a pretty obvious sign of a duff LCD panel - it 'might' actually be the LVDS board, but that's not normally available separately, but comes as part of the panel.

Is the LVDS boaed the same as the T-conn board? I have changed this already. Board that is mounted on the back of the LCD with with 4 ribbon calbes that run to the top of the LCD Screen. Also has a small multi wire cable tat runs to the main board.
