    Thanks for replying. I'm ok with electronics work. As the picture originally collapsed to a vertical line, doesn't that mean the horizontal scan has failed?
    I added a comment earlier but not sure whether it got lost.

    Quasar SP3219V. My toddler has been facinated by by the controls on the TV. Is it possible that I could have sound and no picture from a changed setting, or is this a deeper problem?

Simple problem. In all likelihood, The Vertical Output IC has failed. It will be TDA 8177. Replace. Or, it could also be that the Supply to that IC has failed. Unless you are competent in Solid State repairs, do not try this by yourself. get a professional Technician to have a look.IC should not cost more than 15-20$ pluch Tecnician fees.

    Oops! Sorry, my apologies. Yes you are right. It is the the fault in the Horizontal scan circuits.Could be a Open Hor. Yoke coil, or - most likely a cold solder. Am yet to see a defective Yoke where the Horizontal Scanning coils have failed. seen lots of Vertical Scan coils failing tho'!

    Once again, my apologies.

I got multiple thin colors on the middle of the screen

My 3-year old 52-inch Toshiba flat panel TV (Model # 52RV53U, Serial # AM409000295) developed a display issue (purchased Aug. 2008, manufactured July 2008). Vertical multicolored lines appeared on the screen just left of center. The band of thin vertical bars is 5.5 inches wide. The lines are about 1/16-inch wide. They are stationary, always exactly in same place. They over-ride any other picture on the screen (no transparency). They are there all time even with no video inputs to the TV after the unit is turned on. See picture #1. The TV works well in every other respect, but, obviously, it is annoying to watch the picture with the color band blocking about 1/6 of the picture.

I already swapped out the TCON board with no improvement and replugged the TCON board cables with no improvement.

Most likely it is the flat panel tab bond failure (panel made by Samsung). Further updates will be on my Facebook page.

Vertical lines on my 40 inch lcd mitsubishi hdtv 1080.

I assume your Misubishi is not close to anything electrical. However, it sounds like you have had an interference for some time. This will ineviteably cause the HDTV LCD to collapse. LCD's don't respond well close to heat. Is there a vent close? LCD's do well in a properly vented area but with all this said.......they will pick up interference from anything electrical. A few questions to ask ones self........are there any wireless devices or chargers close to the LCD? Might there be an oven, a/c unit or other wiring with 220 volts anywhere close to the LCD such as in the wall?
The Mitsubishi LT is a very reliable, multi component ready set that allows great viewing with surround sound. However, stop and think about this interference. It is not something in the unit. It is an interference. Look hard and when you've discovered it.....you won't believe how crystal clear this set will be.
Let me know what you find...Thanks for using Fixya and add any comments that may help us help you.

No Picture

If the thin white line you mention is crossing the screen from left to right, your tv is experiencing what is called "vertical collapse". That is a very common problem that is repairable and may be as simple as a few solder connections to replacement of the vertical output IC and a few capacitors. If you can find a qualified shop, take it in and it shouldn't cost much more than $100 to get it fixed.

Bright line coming in center of screen

Hi Shailendrar , your problem sounds like vertical collapse , the whole picture has collapsed into a thin , very bright centre line ? maybe the result of dry solder joints , does banging on the side of the tv temporarily fix ? if so , the circuit board requires inspection for bad solder joints . Alternately the vertical chip/transistor may be blown , replace as required. Cheers T

Philips 28PW6515-05 flat screen TV

You have a bad connection on the CRT board thats mounted on the end of the picture tube it sounds like, or the socket on that board that plugs into the TV set is intermittant or has a bad solder connection on it. Good Luck
