Customer Question

Over the last couple of days, after watching TV for a little while, the screen would go black, but we still had sound. If I turned the TV off and back on again it would be OK. The same thing would happen again and the time would get shorter. I though it might be overheating because it has been very hot and humid and we have no AC. Yesterday I turned it on and got no picture but still had sound. Turning on and off did nothing. Series 5 530 TV. Any thoughts?
JA: What's the make and model of your tv, and can you guesstimate how old it is?
Customer: It is about 8 years old model # *****
JA: What troubleshooting have you tried?
Customer: Nothing yet didn't no where to begin. TV is unplugged at the moment.
JA: The TV expert can solve this for you. Anything else you want him to know before I connect you two?
Customer: No, that should do it.

An important check you should make is this>> 1 when it goes black press the menu button does the menu come up please?

2 If it stays black can you see any visible light at all on the display even feint light?

Let me know please

The screen is all black
Expert:  Anthony_Infotech replied 3 months ago.

So no menu with the check

OK in that case the backlights are outor intermittent on these sets they are controlled by a couple of inverters and its these that are most suspect here, however I am not sure if investing money on boards for this set is a good idea cost of the boards will be around $150_$200

Let me know your thoughts and if you want to push on with repairs
