Which one has Best Chance of being repaired Successfully?

[Paul678]

1) Samsung HPR5012. The screen is in good condition, and
it turns on, but there are black splotches here and there.

2) Vizio P50HDTV10A. Indicator light on front turns on, but
there is no picture.


The p50hdtv10a has WAY more hits on Ebay than the Samsung,
so from a board-swapping point of view, the Vizio has the
best chance of a repair.

Also, what do you think would be a fair price on these?

Thanks much....

board swapping is lazy and uninformative,you swap board,it will have the same crap components,ie bad capacitors series/brands,to do the job properly ,it is more worthwhile to troubleshoot bad components and replace with top quality parts,knowing the tv wont come back to you with the same fault,its not all about making quick money,its about learning ,troubleshooting,diagnosis,sometimes learning about a fault,finding the cause,rectifying that problem,and piece of mind, is far far better than making a quick 20 quid/buck

1) unrepairable fault with screen - no more than $10 for parts only

2) good only if Y-sus or Z-sus only failed, expensive to repair though - no more than $40

ED. on 1) I just realised this is a plasma so 1) could be a Z-sustain fault but ONLY if the patches fill in within 1 minute; otherwise parts of the panel have lost their gases.
