Sanyo 50" Plasma hdtv issues

by rick-m / June 1, 2012 10:41 AM PDT

I have a Sanyo Plasma HDTV model Number: DP50747 Chassis Number: P50747-03 While playing a video game on HDMI channel I heard a pop and the screen went black but there was still sound going through the device and the back lighting was still on. Opened the chassis to check fuses all 7 are good with a multi-meter, but I found 1 capacitor blown on the Y board. Replaced the capacitor but the screen is gray with a black line on the bottom of screen and has no functionality through remote or manual inputs. clicking from power supply that I have never heard before ( believe they are electronic switches) Any help or feedback would be appreciated.

the screen became lighter and an l.e.d started flashing on the logic board could the $28 doller logic board cause the pop no picture ?
P.S is $120 and the y-board is $88 to $149 the good part i guess is the y board is all in one upper ,lower and main!

Crud. In that case...
by Pepe7 / June 2, 2012 5:19 AM PDT should consider buying a new HDTV. Anything over $200 IMO and E to fix a low end flat panel makes little sense when you can find a 50" off brand plasma on sale quite often for not much more, let alone the sales on a name brand with better build quality and PQ. Add in the new warranty and it makes a lot of sense. The 'X' series Pannys are even a better buy IMO than the Sanyos. If you want to stick with a 1080p version which still has the fast switching phosphors (=better performance), look at the 50" U50. Step up from that which includes 3D & more smarttv features would be the 50" UT50. Both < $1000.

FWIW, if you shop at the big box stores like Costco (or another one that accepts american express), it's a cheap way to double the manufacturer's warranty on the new device. You are more likely to find the X series 720p plasmas there though.

Good luck,
