Question about Televison & Video
This indicates the set is in protective shutdown because something has been detected that is either missing or wrong.
The place to begin here would be to follow the power cord inside the set and look at the power supply board. You will be looking for puffed up filter caps and or anything that seems discolored or even burned.
Give me full model number with brand name and I will attempt to research it for you.
Some things to understand about this type of set---for the most part circuit diagrams are not available and individual parts are not sold. All that can be done is check certain voltages and then at some point replace circuit boards. This can get expensive and is like guessing in some ways.
Depending on when the set was made and where(date will be on the back with the model/brand name) boards may or may not be available for it.
I have seen name brands like Dell for example that were two years old and NO BOARDS OR PARTS were available for them. Many of these companies produce a certain number of sets with some held in reserve to be used as replacements for any set that fails in the first year.
After that they do not care as they are off the hook legally.
A lot of this equipment has dropped in cost and they do not want or intend to have to supply parts for them. I will attach a photo of what the caps on the power board (it is from a different set and the caps are usually black with silver tops----any that are puffed up on top and not perfectly flat are gone----If you find this I can tell why and what is needed for a possible do it yourself fix.
