Have TV Questions? Ask a TV Technician
Hello, I'm Shahid and will be happy to assist you. I need additional info to troubleshoot the issue.
- Do you have multimeter and can check volts on circuit boards inside TV if wish to troubleshoot the problem OR want diagnosis and approx cost on repair info only?
This will help me to assist you accordingly.
Nice, please unplug connector from power supply board that goes to right side (x-drive) board, turn On TV and check Vs and Va volts at same connector on power board, expected volts reading is approx 200V and 60V DC even for a second on meter.
Do you get such readings?
Hi, there’s an issue with payment method when I try to accept your phone call offer.
Did you try to check volts requested in my previous reply?
OK, now unplug connector from x-drive board that goes to left side (y-drive) board, set meter on continuity/ ohms range and check resistance between VS & GND pins of x-drive and y-drive boards.
Do you get low/ approx zero ohms reading on any of boards?
OK, do you get zero ohms reading on both boards between Vs and GND pins?
This is odd and I feel it could be bit serious issue in TV like plasma panel internal short, however, there is no other way to confirm it except swap the y-drive and x-drive boards at same time in TV (if you have checked the boards correctly and got zero ohms reading on meter), swapping these tow boards will help to see if TV displays picture OR both boards might got shorted out with loud zap sound if plasma panel has internal short. I wish there was another way around to check the panel but have to take risk of y-drive and x-drive board cost for it.
If both boards go bad again then I'm afraid it needs to replace plasma panel and both drive boards again to get the TV working. Please reply back if you need y-drive and x-drive boards part number info through it would be written on boards as well to search/ google to get price and stock info to order it.
