    it could be any number of issues. if you have disassembly skills and a multi-meter you can troubleshoot with my help. your tv has maybe 10-15 board and several could cause this issue.

Check your cables and TV input settings.  Can you get to the on screen menu?  Does anything appear on the screen when the tv is on?

My LG 60PH6700 plasma TV recently started acting up. Red power light but no sound, no picture. I've replaced the YSUS and Y buffers and the symptom persists. Any other ideas on this? Many thanks.

My lg plasma tv is cutting off the edges of the shows we are watching. I cant find a setting that will take care of it. Can you help


hmm normally these settings are found in the picture settings of the set top box or just a setting in the tv's picture settings now there might be an option to say fill screen that may work best for some or leave the tv in 16:9 some broadcasts may only be in 4:3 at times this is normal broadcasting and not much can be done unless the setting on the picture option is set to fill screen

I have pioneer plasma tv about 6 years old. I turned the power on, sound but no picture. Do you think it is worth fixing?


no
plasma tv units consume considerable power and the latest led units don't so for the extra cost of a new unit , there will be a power saving over the years

I have a rca model led65g55r120q tv flickers and no sound


Check all cables for loose connection, try another input for picture (DVD, BLu-Ray, etc). If none of the other inputs work then it's a panel problem (display) If one or more of the others work then it's a problem with either the tuner or the signal.

I have sound but no picture on my tv


This is a popular question. Most of the time you either need to make sure all connections are not loose or just need to turn off your tv and receiver and unplug. Wait for 1 minute then reboot.
I recommend this short video as it walks you through some diagnostics for other possible problems.
