Thanks for all the great help. The new main board is in and it is working great! Now I discover the HDMI output is bad on the sat dish receiver, but a replacement is on the way! Thank you capkid and Tom!

Thanks capkid, I have one ordered. I'll update after it arrives and I install. Also sent the repair place an email to see if they could repair my old one.Leave a comment:

Where is a good place to get one? I have gone to SJ before but they seem to be out of this one. Also I am concerned about getting the correct one after reading there are different versions? The board has a sticker with BN97-03137A and below that BN41-01170B. The full TV model is PN50B860Y2FXZALeave a comment:

capkid & Tom, I went through the video and had interesting results.
Test 1 - Plugged in all connectors, no jumpers; 5v missing on the main board connector CN801, but I do have 5V on the same connector as the Relay sig and VS-ON; Relay sig (PS-ON) = 3.2; VS-ON = 0.2 When I power up, the relay clicks and 5V assumed to be standby voltage (CN801) & PS-ON bounces up but my meter can't catch. Relay-sig drops in between clicks.
Test 2 - I removed the large connector that goes to main board on...Last edited by BRinSCupstate; 09-08-2013, 07:16 PM.Leave a comment:

That was plugged in but turned off. If I turn on, VS-ON will bounce to about 2.3v only between clicks. It appears first click is trying to power up, next is turning off. Appears that way to me. It is like VS-ON might come higher but it turns off before my digital locks in on it.Leave a comment:

Tom, To confirm... I unplugged the right hand ribbon with clips and jumped 3 & 4 with a hard drive jumper. The symptoms are the same.Leave a comment:

Note, If I try to turn on, VS-On does change and increase when it clicks. I assume the second click is shutting it back down. Hopefully there is no offence done here, but I tried the link below on another web forum earlier and the test points I could find were very close. I can go back through that and list the voltages. With the jumper it stayed on and I could read the voltages.

Tom, sorry but could you explain the procedure in more detail. My layout is different and I have a 7 pin, 6 wire connector in that location. I'm also not sure what the LVDS cable is.
CAPKID, I see VS-on on the connector going to what I believe is the control board at bottom center. I assume I can reference it to an exposed screw. If that is it, I have no voltage on VS-ON with it plugged in and not turned on. I can't find PS-on....Leave a comment:

I'm new to troubleshooting TV's so I am not familiar with all the terms. We had a lightning storm. The TV was off but apparently was damaged. The red LED on the front is on when plugged in. I can turn on by remote or touch pad. It clicks like it is trying to power up and then about 5 seconds later clicks again and then continually repeats with LED 2001 and LED2002 (bottom middle board under plate) alternating coming on. I tried disconnecting Y-sustain left side, Z-sustain right top, but no change. I have checked all fuses on the above referenced boards as well as on the power supply. Note: a year... -

Hi, I'm brinSCupstate. Thant would be South Carolina of USA. I started my career several years back (1984) in servicing electronic equipment related to textiles. I have only worked in manufacturing and have mainly troubleshot to the board level. I have an interest in being able to fix TV's, specifically mine right now. I have fixed it once but a blown chip on the power supply was pretty obvious. This looks like a good place to learn!Leave a comment:
