Question about Zenith B32A24Z 32" TV
My Zenith tv (8yrs old) goes completely blank while watching it. It started by the picture fading in and out then goes blank. Sometimes you turn it on and watch it for a few minutes and then it goes blank w/no waring. It will stay out for the whole day. Turn on next day and it works for the whole day. While the screen is blank you still have sound. This has been happening about 2 months. It seems to be happening more frequently now. Is this something that can be fixed for a reasonable price or is the TV shot?
The effect you described sounds a lot like a failed solder joint.
There are points on the circuit board that are subjected to heating and cooling each time the set is powered up, then down.
The solder joints near these areas can fail from metal fatigue as will any metal that is forced to expand and contract repeatedly.
These fractures are minute and can often only be seen under magnification.
Once found, they are simple to fix; removal of the old solder and resoldering will restore electrical contact in seconds.
If you can find a gray-haired tech nearby who is retired, maybe early since repair is a business stagnated by cheap labor in Asia, he/she will know where these areas are and can robably get rid of your lottery-like operation.
Or, if you have way too much time on your hands and are willing to buy a decent soldering iron and dig into the guts of your set, you can probably find the problem yourself.
While semiconductors do fail (sometimes for the same reason), since the set does sometimes restore itself, it isn't likely that any of those has died.
I would be torn to toss the set if it is otherwise OK for the simple reason that if repaired, it may outlast 80% of those bought in the last 2 years.
It is amazing the number of problems that are happening on new, sophisticated sets and it is traceable to lousy quality in parts and assembly.
I have one LCD set I will probably junk this year that is only 2 years old, flawed when I bought it new, and has a failure producing a vertical black stripe that would require replacment of the $4-500 panel.
Junk - Specifically, WALMART junk.
