Hello all,
I've come across a non-working Vizio 50" Plasma TV that was abandoned by it's owner. It is a Vizio JV50P HDTV10A. The inside label says it's made by LG and it's model number PDP50X4TA35.
The previous owner said they watched the TV all day and the next morning they went to turn it on and got nothing, other than a click. No pops, smell or picture/sound problems prior to it dying.
I pulled the back and had a look around. I don't see any evidence of bad capacitors, although I did check the ESR many of the larger ones on several boards. The power supply looks in very good shape. All the voltages that are labeled are within specs.
When I plug the TV in I can turn the TV on with either the remote or by pushing the panel's power button. I get two clicks, and the TV appears to power up normally. On the controller board I see 4 LEDs, labeled D5, D4, D3 and D2. All except D2 are lit. If the lights in the room are dim you can see the Plasma panel glow, but there is no picture. Also, once the TV is turned on the is no response from either the remote or the panel's controls (i.e. you can't turn it off except by pulling the plug).
I can let the TV run for a while and if I do a "finger" test on some of the components I see they are getting warm, as I would expect if they were operating normally. But there is absolutely no picture or sound, nor is there any control after the initial power up.
I can hear a slight "buzz" coming from the ZSUS and YSUS boards. It appears they are working normally, and they have proper voltages applied to them.
Because of the lack of control after the set is turned on I'm leaning towards the Main Board as being the problem. It's part number is 3850-0162-0150 (2A). I am also considering the controller board, but it would help if I knew what the meaning of the LEDs were.
Any help would be appreciated. I can post pics if need be, but I really don't think they are necessary.
Thanks,
Chuck
