Question about Samsung LN-S4051D 40 in. LCD Television

1 Answer

Samsung 42in Plasma 1 year old

I have a Samsung 42 in Plasma Tv just 1 year old. Thank God I purchased the extended warranty. For 1 year the TV worked fine, however just 7 days past the manufacture warranty the TV began to show Blue Streaks alone the top and left edges, also a blue circle about 5 inces wide in the center of the screen. This blue would never show up when first turning the tv on, be never fails to appear after being on for 20 minutes.

Extended warranty sent out the first company, and replaced the something called the "Scan Board" this was done in my home. Needless to say the tech left and after the TV warmed up the same problem occured.

I called the warranty company again, This time they sent out a Different company, which picked up the TV on Monday, and returned it one day later on tuesday.

This is what the ticket say they did. "adjusted V.S. Voltage"

Here are my questions for you.

(1) Is this a temporary fix?
(2) If the TV worked fine for 1 year, how is it possible for it to get out of adjustment all by it self.

I ask these questions because the picture does not look the same. It is true the blue streaks are gone but the pitcure doe snot look the same, The picture is not as sharp as it was, and it is not as bright.

Please give me your opinion.

VS is vertical scan of course it is controlled by applying voltage, lower or higher you affect the scan, it appears as focus or sharpness, if it is outside the specifications listed on the back cover(inside) then it will not function properly. definitely get with samsung on this and get a ticket number so they can not just blow you off, if you have an extended warranty they might have to replace the tv as this sounds like it may be a tube issue not just a scan issue, also don't let the tech leave until the tv has warmed up and the image is either the way you like it of he stays.

Samsung 50'' Plasma TV won't turn on anymore

If your tv is within the one year warranty period then call 1-800-Samsung for warranty repair. Look at your tv purchase receipt for the Purchase Date. You have one year from the date of purchase to get warranty repair.

Panasonic Viera 46" plasma~no sound, no picture

I would use the warranty at Bestbuy at that point. Opening up the TV would most likely void the warranty.

Overall Warranty 1 Year - this may be incorrect.

My monitors have 3 years, did you purchase a extended warranty?

check with hitachi or your dealer about the warranty it may get it repaired for free, if its still under warranty.

maybe not but its worth it to check.

LG RT-42P245V-Band of pink

The PDP (plasma) panel has gone bad and need to be replaced. This is not a user serviceable part and cost about 1/3 of buying a new unit plus the cost of labor for a two-man job. I would hope that this unit was purchased less than 1 year as warranty for parts and labor is 1 year. If not I do hope you purchased an extended warranty or paid it with a MasterCard (some MC card provider extends the warranty by another year). Cost of repair for flat screen TVs are high so it really a wise investment to purchase extended warranty. Fixya offers extended warranty on your future electronics purchase. Hope this helps.
