Re: Looking for a new TV, what is a reliable,durable brand?LCD,LED or PLASMA?
Happened to notice this post and decided to chime in. I'm picking up a Panny TC-P50S60 tomorrow. This is the entry level model without a anti-glare coating (?). Did a lot of research on this model and was very impressed. Even saw a review comparing the black level and PQ, somewhat, to the 9G KURO, (which I owned at one time).
I'll be running this, as usual, from an XBMC box with DVD rips and torrents. Setting up a Raspberry Pi openELEC media center.
You can get this unit for...

Possible Acquire LG 50PC5D Plasma
Owner said unit blew a fuse and won't turn on. Anybody have experience with the history on this TV?
He also stated light turns green then back to red. That's all the info I have at the moment. -

Thank you very much, Tom. I was afraid of that.Leave a comment:

Re: Vizio VP503 HDTV10a Black Screen
Tom66; I think I really stepped in it this time. The C2 board arrived today. Installed it and within a millisecond, a puff of smoke after power button on. Burnt the same 2 resistors again. I'm posting 2 pics. If you will, please look at them and tell me where to check, and how, for this over voltage or short. I have Photoshop so I can break the .jpg into sections if you need it. Thanks...Leave a comment:

Re: Adusting Horiz and Vert size Help!
I did this years ago. You have to go to the AVS Forum. Someone wrote a scan program for your computer that allows you to access your video card and make fine adjustments to the overscan. Or you can buy a video card with HDMI out....Leave a comment:

Re: Vizio VP503 HDTV10a Black Screen
I almost feel as if I'm harassing you Tom. I appreciate the info on ceramic caps. However, it doesn't tell me, with the measurements, what could be wrong. So I ordered a TNPA4433AB C2 buffer board. I have to assume that I might burn this new board out if there is another problem lurking in the wings. Do you have any guidance?Leave a comment:

Re: Vizio VP503 HDTV10a Black Screen
OK. I'm just completely lost by what you're saying above. I removed C224 and tested across the cap and the tabs and got "0.F". "[B]if it's near zero when not installed then it could be that ceramic cap instead[/B]". I'm sorry, but, could you be a little more clear? You're dealing with a bonehead here.Re: Vizio VP503 HDTV10a Black Screen

Yes, the panel ribbon was off and the board removed from the set. I will remove the caps tomorrow and test. Thank you....Leave a comment:

Re: Vizio VP503 HDTV10a Black Screen
There are 6 caps on this board like C224. [B][U]All [/U][/B]show zero resistance. However, testing with a Blue ESR meter (which I'm not sure I'm reading right) shows an ESR of 5.2 on the suspect caps. The other 4 caps show a 3.7/3.8 ESRRe: Vizio VP503 HDTV10a Black Screen

Re: Vizio VP503 HDTV10a Black Screen
I might be grasping at straws here, but is there any way to test the tabs themselves to see if they're shorted? Would that tell me anything? I tried continuity testing from the traces to ground on the 3tabs and got a lot of beeps because They are so close together. I hate to give up....Leave a comment:

Tom, I think you nailed it. Photos show resistors on connectors CB7 and CB8. CB7's seem to have a burn mark. I will research on how to test these....Leave a comment:

Re: Vizio VP503 HDTV10a Black Screen
(Tom; please comment on post #106)
I think I made a new discovery (?) and need suggestions. In the photos you can see that the vertical black bar was replaced by color moving pixels after removing the tab from connector CB7 on the C2 board. Does this mean it's a bad C2 buffer and not the panel? The bar is 4" wide and runs vertical from top to bottom....Leave a comment:

Re: Vizio VP503 HDTV10a Black Screen
tom66; I don't generally go against your recommendations, but here is my question:
If the panel is bad because of the black vertical bar there would be no sense in going any further. So, I disconnected the tabs on the C1 and C2 boards (where the black bar intersects) to see if they had the bonded diodes. I did not see any (see pics). I did remove the D board at one time so those tabs might be misaligned or the C and D boards are bad.
I'm also loading 2 URL's that can be put into your manuals section if you don't...Leave a comment:

Re: Vizio VP503 HDTV10a Black Screen
OK. So now I'm totally confused!!!! The vertical bar was not there before I installed the new SU board. At the same time I could not get the set to recognize inputs from Cable, HDMI 1 or HDMI 2 (don't know if that makes a difference). However, I isolated the SU and added the jumper, now there is no black bar, just prime. Oh, man, I'm drowning here!!!
I will be gone until tomorrow morning, please everybody chime in with some suggestions.Leave a comment:

Re: Vizio VP503 HDTV10a Black Screen (Some Success!)
I put the SU board in this morning with some success. It seems with this hybrid Panasonic that one IC on the SU board [B][U]CAN[/U][/B] take this set down with [B][U]Black Screen[/U][/B]. However, as you can see in the pics, (I rotated them for better clarity) the ribbon cables still need to be adjusted and I have a black vertical bar down the center. Is this (Black bar) due to a misaligned cable on a C board??
Right now the TV is scanning for cable stations and is not shutting off automatically. If there is no...Leave a comment:

Re: Vizio VP503 HDTV10a Black Screen
Did You mean SS?
Question: Within the past year we had several storms and lost power. The 1st time for 5 days and the 2nd for 15 hours. I powered my house with a standard gas generator for the heating boiler, lights, fridge and the TV I am currently working on. With the TV I did this for about 3 hours each evening. When not being used (the TV) it was unplugged from the system. The generator was running when the TV was plugged in to avoid a surge when starting it. I used heavy duty extension cords.

Yes. On both the SC and SS. They only fade out after the shut down. Before, when I had the 30 second shut down, they faded out after 20 seconds....Leave a comment:

Re: Vizio VP503 HDTV10a Black Screen
SD46 and SD42 disconnected. No SU installed. Jumper in place. Power on to shut down still at 40 seconds. However, I could hear a slight hum from the lower part of the SC board. I'm waiting for an answer about an SU board.Leave a comment:
