I've had the TV since 2007, I bought it new.
I continue to have sound and can change the channel (on the cable box) and the sound changes with the cable-box channel.
I have tried to pull up the menu and change the TV channel but there is no difference in the picture
Yes I have a flashlight
why YES, yes I did. the light source must be the issue
I have a meter, but it is dangerous in my hands.
can you guestimate the cost of repair and recommend a repair location please?
There issue is either caused by a failing/faulty component on the power supply in the 15-20 volt output that drives the inverters, in which case you're looking at around $175-$200 parts and labor for repairs.
Or one of the transformers on the Inverter board is bad in which case the Inverter would be replaced. Average cost for this repair is around $150 parts and labor.
