A blown fuse is only a symptom, not the problem. The problem is somewhere else in the unit... From what you're describing here something is keeping your HV down and that could be any number circuits... This type of problem is a challenge even for the best of technicians and not something you're going to resolve with less than several thousand dollars worth of test equipment at hand and one heck of a lot more experience than I've ever seen on this board... No disrespect intended... That said, I would start by testing the regulator circuit. Look for any signs of heat stressed components. Test the HOT for short and check the FBT and splitter. Something in the B+ line is the culprit. But my best advice is take it to a reputable shop and get an estimate before any repairs are done. If you don't understand ask for explanations. If that isn't doing it ask different shop or get a second opinion. Good Luck Bill

Sound no picture

Hello,
Try connecting TV to cable direct also try unplugging both converter and TV for wile like 5 mins plug both back in see if TV and converter sync.
But if it still doesn't work...

More than likely this will be down to your Y Sustain board has gone faulty, when the back is off your TV it is on the left hand side and will probably have a fuse that has blown, replacing the fuse will not solve the problem as it is the IMP under the heatsink that has gone faulty.
You should get the part number of the board and Google or Ebay for a replacement.
Hope this help

Pop sound then no picture, just sound

I assume this is a plasma TV? You will have a fuse blown on either the Y or Z sutain board, there is also a possibility one of the driver IC's has blown on the buffer board, this will shut down the screen & leave the audio working normally. You can check these boards which sit on the left & right hand sides of the screen.

Lg plasma 42PC3D no picture with sound

I know you already replaced the board, this is for future searchers. If you heard a popping sound, then the picture went out, there is a 32 pin Sanyo module that goes bad on the board. That's probably what caused the fuse to blow. Replace the module, then replace the fuse. The module is less than half the cost of a used board. Since this was a popular model TV, there are lots of replacement boards on the used market.
