Facing TV Problems? Ask a TV Technician.
Hello My name is ***** ***** I'll be helping you with this.A few questions coming up and please note that there may be delays between replies if i have to gather various info ;Please send me a hello so i know you can see my reply ?
Did you replace both board at the same time or you tried one first then the other ?
Note that I do not send phone offers myself , they are automated by the website and I`m not available for it at this time but another expert might be if you`d rather do this on the phone .
O.k then you mean that replacing the power board alone still gave you a blinking light ?
O.k then for a test re-install your old power board with the new main
No problem ,take your time
Do you have a voltmeter ?
Too bad we could`ve tested what is coming from the main board and out the power supply
At this point this is what needs to be done as i believe one of your new board is not working correctly
Just for a test though i will ask you to pull out a couple of lug s and see if that affects it
Be right back
First disconnect the 2 flat ribbon cables at connectors TCN3 and TCN4 and try again , see if the backlight comes on ?
O.k , re-install those and make sure you lock the clips over the ribbon cables
You did notice there was a lock there yes ?
Now disconnect LCN1 and 2 on the power board one at a time and try to power up the tv in between each , see if the light at the front does anything
By the way , pull the power cord each time for those
Somehow i trust more your old main board than the new one , looks to me like it responds to and abnormal condition by blinking while the new one seems to be dead
I would try to re-install the new main and try those plugs again to see if you get anything
Try the test you just did with the old main board , that new one doesn`t seem to react to anything
O.k then this would need to get down to voltage measurements , no other ways now
You could get a cheap digital voltmeter /multimeter at places like home depot tomorrow for less than 20 bucks and beside this job it could come in handy for other things in the future
No problem but if you change your mind i`ll be here .
I will close that phone request as we won`t be using it , you may see a charge for it but it will be credited when i send it in as incomplete /canceled
There won`t be any charges on that
