Hello WelcomeThanks for using JustAnswerIf you could just answer the below info requests please this will help me a lot thanks!Was their any prior problems ?perhaps the set was slow coming on?Anthony
No , there were no prior problems wih this TV. in fact that was the very first problem encountered.
The red light at the bottom righ corner of the tv blinks once the tv power plug is plugged in.
HiAs you have already replaced the powerboard the next move is the mainboard, are you OK replacing this?Anthony
I replaced the main board and no change
Please advise the next step
HiSorry you said you only replaced the powerboard , are you saying you replaced the powerboard and the mainboard?Anthony
I replaced both the power board and the main board and tv still does not come on, but red light at bottom right corner only blinks
i would try and unplug the driver board t com up at the top of the screen then power it up if it comes on and stays on the problem in their
I unplug the driver board t com at the top of the screen and no change; it still does not come on
Hi well not much left let's try the plugs from PS to the main board do one at a time then apply power to ti one of them when unplugged the screen will turn on that should rule out the screen.
I have tried as you suggested but no change
unless u got a defective power board not much left but the display
expert tv technician for over 25 years
what do you mean the
Display is the screen but I'm really starting to think u may have a defective power board these power boards have history of bad solder joints
Are you suggesting that I possibly may have purchased a defective power board?
hi have a question did u change both board at the same time?
No, I ordered and changed the main board first then ordered and changed the power board
hey since there isn't much left that can be changed we are hitting a brick wall on of the new boards may have a problem you could try different combinations of the boards put one old board in with one new board and see if you get any change at all but beyond that you may have to bring it in for service i will help you any way i can if you have more questions
I have already tried that too
only parts that are left is the back light inverter but i think that is part of screen and dose not come separate of the display panel
