Question about Televison & Video

1 Answer

I have a Hewitt Package 42" tv, one day the picture just stopped working, we still had sound, but no picture (prior to that it would change channels by itself), i looked online and i ended up sending the YSUS board to Texas to get fixed, i got it back yesterday, installed it and it worked fine, until today, it went black again. Could it just have been a defaulty part on the YSUS board, or is there something wrong with the ZSUS board now?

If they " REPAIRED " the ysus board versus relacing it- then yes. It;'s some times called a domino effect. the "CIRCUIT BOARD " is "wave soldered " that means most " SURFACE MOUNT COMPONENTS " were " PLACED " by machine then soldered to board with a conveyer belt through molten solder. Over time these connections may weaken and " intermittently " open up. The process of being removed and shipped may have exascerbated any original issue. You can check for these defects with a magnifying glass or jewelers loupe. Any " LEAD "soldered through the board will be soldered on both sides-and will need to be checke for circular ring shaped cracks near the surface, cold solder joints at the surface mount level," PICK AND PLACE MANUFACTURING " may be checked for hairline cracks in silver " CIRCUIT TRACE " nearest the edge of the soldered " SURFACE MOUNTED COMPONENT " good luck.

My LG HD tv screen has a wide, gray band on either side of the picture


Try changing 'perspective' or screen ratio.
This may work, but could also stretch the picture too wide,
On my non-LG TV this is called 'aspect ratio' under the 'picture' menu.

I bought a brand new 42 inch plasma vi vo tv 2


New products do fail. The set should certainly be under warranty. I would speak to the dealer you purchased the unit from and see what they suggest. Don't remove the rear cover, or do anything else to give anyone a reason to void your warranty. Most brands are 90 days on parts and labor.
