Facing TV Problems? Ask a TV Technician.
HelloMy 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 ?
Is the OPC light also blinking ?
O.k then look at the power light and tell me if for example there is say 2 blinks /pause /2 blinks and so on
Give me the count please
I`m ready to accept your phone request but first i want to make sure you understand that this cost an extra $26Do you still want that call or do you wish to continue in chat mode ?
O.k then this is not good , it indicates a lcd panel error
Try this ;
Unplug the tv`s power cord 20 secs or so then press and hold VOLUME DOWN and INPUT directly on the tv (not the remote) while you plug in the power cordTell me if it comes on with a letter K on the screen
I will now close that phone offer before it gets posted to the board and someone take you up on that .
The way to close the phone offer is to accept it first to remove it from the board then cancel it , so you may see a charge for it but it will be credited as i closed it as incomplete
That's odd , let me check the manual and I will tell you which is what
Click the link below for a picture of them
O.k then we`ll try the force mode
same thing but this time with the channel down and volume up buttons
O.k then you more than likely have a failed inverter board
There are two of them ,master and slave that get replaced at the same time usually and they cost around $40 a piece
More to come , let me type this down
Before ordering those inverters part # RUNTKA478WJZZ and RUNTKA479WJZZ you would need to check the 24 volts that feeds them coming from the power board
If you have a voltmeter and are into repairing this yourself then I will show you were to test and also find those boards for you
If that is not your cup of tea so to speak then to have this repaired at home could cost you around $250 to $300 parts included and perhaps $50 less if you take it to the shop yourself but if i may be frank , considering the age of the tv at 10 years old and the fact that you can get a new 50" tv with all the bells and whistles for around or less than $400 ,I would think twice before investing that kind of money into this one.
I think your money would be better invested in a new tv .
No problem , much welcome
As i can`t be there myself with tools and meters I can only go by the code you gave me and manual
Return it and get that main if you figure this is what it is !!
Did you check that 24 volts anyway ?
Did you replace the main board yet or you figure that is the problem
That code points to a problem either with the inverters or worse , the LCD panel itself
See what i said above " O.k then this is not good , it indicates a lcd panel error "
Tried to save your tv as there was a chance the system processor mistook the inverter problem for a lcd panel problem
Again , did you check the power supply 24 volts as i suggested first before ordering anything ?
Never mind what i said about the main board above , a mistake this morning but in any case that code never points to a power supply issue and again I told you to check the 24 volts !!
Better yet i even said " I will show you were to test and also find those boards for you "
Apparently you did not check it so the fault is not mine here if you did not follow my advices
Then sorry but you took a chance without testing
In any case it is very seldom that the power board will be the culprit , perhaps a 5% chance and you happened to be in it
