I have a maxent 42 inch tv for the last 2-3 weeks the picture keeps blinking intermitentley last night while watching it we heard a pop and we have sound but no picture any answers

you lcd tv not setup problem. that" s main board gone in. you need a tachnician for it.

Hi!

The sound you heard is most likely produced by a capacitor that blowed up, most likely in the power supply part of the TV.
There is no way that the gas escaped since it is contained in very small cells and of course there is nothing like a procedure to "refill it"

The repair can be done only by a professional, and it coul not cost too much, comparing to the price of the TV itself.

Check high voltage circuit. This is near where the 120 volt cord is plugged in and a high voltage transformer, where there should be capacitor (or two). Check the voltage - should be 390 to 400 volts. If not less than 390, near to replace the capacitor.

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.

Hi , I recently had the same problem which I was determined to fix . So I did a few weeks of research to find that it was the Y SUS board which burns out. I'm sure you realized that the TV gets hot. Personally I think this is why. circuit boards don't like heat and I've learned that the cooling fans are a joke. I replaced the board and got my picture back. I proved the fan theory because after the screen started to act up. I placed a cooling fan near the vent holes on top and the problem cleared right up,It also helps if you lower the brightness which helps out on the heat situation.I will soon be adding a fan with a temp. sensor. This shoud help if your screen has lines when you initially turn the cool TV on.then I have Some other costless solutions. Hope this helped these are great TV's and like our cars we maintain them not throw them away..................................Mr Wiseman

Bad lamp and/or lamp driver. Try replacing the lamp first.

ysus pcb that supplies voltage to the panel is faulty

sounds like it may be a software upgrade
