Hi and thank you for using justanswer.I`m going to help you with your tv but first i will have a few questions;
You are saying that this problem has been there for a while now ?Getting worse everyday ?
Is that red light flashing at the front ?
Also, Could you please lookup your tv`s model number located on the back cover ?
I will wait for a while to see if you become available for chat, just send me a reply and i should be with you within a couple of minutes.
This has happened before, maybe 3 times over the past month, but by no means on a regular basis
The red light is on but not flashing
the model is DX-32L150A11
O.k thank youThere is not much info on your model so this may require a bit of troubleshooting.
Can you try to knock or tap the sides and rear of the tv then try to turn it on ?I know this may seem basic but the idea is to see if perhaps there might be a loose connection inside the set.
I'll give it a shot
tried it, sorry, no luck
Did you try to unplug it 5 minutes or so today ?
Yes, for over an hour
The first two circuits to suspect in your case is; the power supply circuit and the main board, if you want to take a look inside , i have pictures of those boards.
I would have a few components for you to look at.
cool, so first I remove the back of the TV?
That would be the first thing yes
what i can do is switch this chat to standard Q&A mode and you will get an email with a link to get back to me once you are ready.
In the mean time i will upload those pictures.
Talk to you soon and check your emails in a few
We are now in Q&A mode.
Here is the first circuit, that is the power supply board.
You`ll see that i circled some capacitors, i`d like you to look at them closely to see if any of them appear to have a rounded/swollen top compare to others.
Their tops should be perfectly flat.
Here it is;
o.k then here is your main board, i`d like you to try and pull out and back in all the connectors on it, same thing on the power circuit .
If you removed the stand in order to remove the back cover, you can re-install it temporarily and stand up the tv.
Plug it in and push on the connectors while you try to turn it on.
No problem, this is not like the old tv sets that kept voltages charged in the picture tube.
If you`re not crazy about the idea then you could put on some rubber gloves.
Just keep on hand off the metal chassis while you`re working with the other one.
The connectors are the plugs that connect with wires to the circuit board and usually you can just pull them off and on by hand although some of them might have a clip that you need to squeeze in order to unlock them.
By the way; do you have a voltmeter ??
Sorry was a bit busy.
Some of those connectors might be stiff to come out, if they don`t want to come its o.k let them be and just make sure they are pushed in securely.
You don`t want to pull too hard on the wiring and break any !!
Well, then i`m afraid the next steps would be to measure the voltages coming in and out of the power supply circuit .
If i was shure enough of the power supply being defective, i would give you an address where you could get it but without measurements i cannot be positive on that.
It could be your main board who is defective just as well.
