You need to replace your lower Y drive board. Looking at the back of the set it is the board on the far left, bottom of the two. Should be about $50.00.

The problem is the "Y-SUS" board. It is inside the set on the left side with several aluminum heat sinks, under the left side brace bar. You can order this board from Union Electronics at www.ued.com .Search for part number: TNPA3243AB-PA

It lists for about 115$

The problem is with the YSUS board. Also 1 or two fuses (4A) will be blown so you will need to replace those along with the YPPD-J018C Hybrid IC module that is under the large heat-sink. I'm an EE in my day job so I have done this sort of repair from time to time but it can be intimidating unless you have very good soldering skills and a good solder station such as a MetCal. You will need a lot of heat to free the pins before prying this IC up. Failure to do it correctly may lift some of the delicate traces and the new part will not work! When removing the IC I always add leaded solder on these lead-free boards because it flows better. Also adding extra flux and using a Soldapullit Solder Tool works well. You keep adding the solder and sucking it back up...until the pins are relatively clean. Removing the IC still took me about 1/2 hr. to get enough solder sucked up until I finally was able to stick a screwdriver under it and pry it up. Do this gently, on several places on the IC to break it loose. On my board Q1 was blown but since there 4 of these same little semi-conductors, your problem might be Q2, Q3, or Q4? They are easy to spot because they blow apart catastrophically, there was black soot around mine. Also, one of the main reason this part failed is because the white heat sink grease was dry. This means that the heat-sink was not able to adsorb the heat from the board as well anymore and then it just got too hot and failed. So use a good high end thermal grease when you put the new YPPD-J018C part back on the heatsink. Something with silver like Artic Silver will cost about $10.00 a tube. This will make the TV last much longer. The YPPD-J018C part should run you anywhere from $39.95-$49.95 plus shipping. Both Suburban Electronics in MD. and Rich-Tech have the part. Good luck!

If it is not a loose connection (internally), it may be most probably related to your picture tube. Check it out and if found faulty get it replaced. If your are in any warranty period (I don't think so since it is 3-5 years old), don't do anything and just inform them, or else you will loose your warranty security.
