Question about LG Televison & Video

Open Question

LG plasma tv,60PB6650.It just shut off,no video or sound,but turning on and off on it's own.You hear a click,see the red powerlight turn on and second later hear another click,the powerlight goes off

The on/off is continuous. I took off the back panel and it doesn't appear like anything is blown, burnt or bulging, but the clicking noise is definitely coming from a black rectangular capacitor on the power control board. I'm assuming I have to replace the board, #EAY63168603

SOURCE: LG 42 Plasma try's to turn on but just goes back into "stanby" ?

Check to see if you get Va and Vs voltages from the power supply. There should be some wires running to the y-sus. A couple of those wires will be labeled va and vs. Are they present? There will be a sticker stuck to the panel somewhere telling you what they should be.

This is a common problem with these TVs. You can download the official Sanyo repair manual for this TV (DP42746) at http://www.eserviceinfo.com/downloadsm/43343/sanyo_dp42746.html. I uploaded it here when I had the same issue with my TV last year. The solution is almost always to replace the Power Board (Y-Main) and the Upper and Lower Y Buffers. The parts and costs (from Sanyo in July 2009) are listed below (NOTE: Sanyo will not ship these parts to anyone but a repair shop): 1. V4 Y-Main (Y-Sustain) Circuit Board (Part # LJ92-01200A, Alt Part # LJ41-02759A) - USD $139.00
2. Upper Y-Buffer Circuit Board (Part # LJ92-01202A, Alt Part # LJ41-02760) - USD $64.00
3. Lower Y-Buffer Circuit Board (Part # LJ92-01203A, Alt Part # LJ41-02761A) - USD $64.00
Sanyo charges USD $10.50 for shipping, which brings the total cost for parts to USD $277.50. From my research, a shop would probably charge between USD $500 and $700 to do this repair. FYI - there is a class action lawsuit pending against Sanyo for this issue. The V4 Y-Main (Y-Sustain) Circuit Boards fail VERY frequently in this TV due to overheating. Hope this helps.
