Maxent MX-42VM11 Plasma.
TV has sound but no picture.
I checked power supply and power assy for voltage and its fine.
I removed the Y-sus board and started checking for continuity, I started with the fuse (good)
Then resistors, I found one very small resistor solid green no markings and it read infinity on two different multimeters. That resistor is locate very close to the fuse area next to where voltage plugs in to the board.
I’m reading about capacitors and how check them next.
Is there anything or a different way I should approach this board?
Your solid green "resistor" is probably a fuse and will have an amp rating stamped on it, if you can read it with a magnifying glass. Before you replace that you need to find out what else on the board or somewhere else in the TV is blowing the fuse. Resistors have bands to denote their value unless it is a large power resistor and the value is written on it.
SOURCE: I checked power supply and
The small green resistor could be a pico fuse, check the markings on the board and look for an F and a number next to it. If that fuse is blown, it means something (Mosfet, transistor) got shorted to blow the fuse. To measure capacitors, you will need a capacitance meter but they rarely become shorted, so I would focus on the mosfets and transistors.
SOURCE: I have a 3 year old Maxent MX-42VM11 plasma tv with no pic/sound
swollen capasitors, replaceing will cost $500, so best to get another one, 42'' samsung will sell for about $800. the pn42a450
once a plasma has a problem, fixing it or not, more problems will occure, trust me, i am the flat pannel guru.
SOURCE: I HAVE MAXENT 42INCH PLSSMA I HAVE NO PICTURE I DO HAVE SOUNE
HERE IS YOUR PART NUMBER 6871QYH039B Y SUSTAIN BORD AND CHECK WITH SHOPJIMMY.COM OR DEALTIME.COM THEY NORMALLY HAVE THIS TYPE OF PARTS
GOOD LUCK
SOURCE: x-sus board replaced year later same pop of death
test the main board next to it- the are usually replaced together sometimes called the scan board-you can check for blown fuses on the x sus and put the back of your hand to the heat sinks- see if they warm up or not (be careful) if they stay cold with set on for several minutes then its dead
SOURCE: when the tv goes pop how do you tell which board
The majority of the time it is the Y Sustain module. I, myself being in the service industry, I always replace the Y drive boards also. The Y main is the large board on the left and connected to that is the y drive boards or board, depending on the model. Check for pico fuses open on the Y and that's a give-a-way.
