Question about Maxent MX-42VM10 42 in. HD-Ready Plasma Television
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?

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.

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.

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

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.
