Coax input died...can I repair/replace part or work around?

I purchased a refurbished TCL LE39FHDF3300 39in 1080p LED HDTV tv and the warranty is out. Last week the tv starting making a popping sound when we watched tv...did not do it when watching Roku. The next day I had no input on the tv side...Roku still works fine. I hooked up a portable tv to the coax and it worked ok...but have a blue screen/no signal on the I assume the coax input is dead. Are there replaceable parts in the TCL to fix this problem or do I need to purchase a demodulator and use the AV input for my tv watching? I had an analog pass-through DVT converter box and attempted to do the work around but all I get is a weak signal message.

My tv is connected to a Dual Satellite box from DISHNetwork a VIP222K and is operating as TV2

Sounds like some caps on your AV board went out. Have you tried to input your VIP222K YPrPB cable or RCA/S-Video to your TV. that should bypass the coax altogether.


All other inputs seem to work, but I have RG6 installed coming from my Sat box in the living room and running a 60' RGB cable is not an option...was wanting to use the existing coax and use some type of converter to use one of the other inputs...something relatively inexpensive.

Lee Colley, in that case the only thing I know of is a RF Coax To RCA Composite Video Audio Demodulator. something like this should work. There might be cheaper ones available. Why not take a look inside your TV and see what it needs to repair. Hope this helps, good luck.
