    Most probably it is the TCON board which has gone bad.

I have sound but no picture. Turns on/off with no problem. Checked settings including playing DVD and other video settings- picture just went out


The model indicated has 3 picture tubes (right model?) and will blank or turn the tubes off for several reasons--almost all are protection.

In this kind of set if vertical loss of sweep (in old sets you would see just a white line left to right) it will not permit the tubes to be on as it would burn a line instantly in all three tubes screens.

If this model not likely to be a do it yourself repair.

Tip

TV shows either: black screen with: white vertical or, horizontal line


If Your screen shows a: white vertical line on a black screen or, a white horizontal line on a black screen:
Your TV vertical or, horizontal power transistor or, chip is getting too hot.
A vertical line indicates the horizontal circuit is at fault, a horizontal line indicates the vertical circuit is at fault.
To troubleshoot: Turn on your TV untill the line shows then: after about a minute, remove power (unplug) the TV, remove the TV back cover, find the too hot transistor or, chip; using component coolant; spray the too hot component with the component cooler until the screen comes back to normal. To fix: apply white coolant cream to the back of the too hot transistor or, chip. or, if there is room, a small fan can be wired in to cool the part. Radioshack sells the cream and, also a "component cooler spray" that should find and, fix this problem, also; with power removed you can, if you feel it is safe; carefully (with only one hand) feel the part; it will be very hot! (it could burn your finger!) Do not touch anything else! (this will not hurt the tv; when the picture comes back on (the offending part has cooled) you have found the problem part.

Hi I have a sharp 27H S60, has worked fine for many years. Now, I get fine sound but no picture. When it is first turned on I get a thick white line in the center of the screen for a second, then it is...


The problem is a vertical deflection issue, it means the picture from top to bottom has collapsed. The set will require two or three capacitors and an ic and it is quite fixable.

Picture has white horizonal line accross it


You have a vertical collapse. Not sure if its worth fixing because i don't know what type of set it is or how old. But vertical is not usually expensive to fix. Possibly just replace vertical ic

Philips LCD model 26TA1000, vertical lines and blank white screen with no picture


it would be easier to find it stripped from a damaged set on ebay.
I see several there but need the part number to search
of course you may purchase that and find it to be the lcd driver.hopefully not.

The problem you are having is a vertical deflection problem. The screen is being compressed to a thin white line. It's probably a defective vertical output module or transistor. This part is not too expensive. Less likely would be a vertical deflection coil, which would be more expensive because its usually glued to the picture tube and harder to replace. You'll need to take your set to service center to have it serviced.

Good Luck!

Mitsubishis TV Problem


have a Mitsubishi TV 1993. Model CS-35301. The problem is that there is a white line that is running through a blank screen. The sound is fine just no picture. Have you heard of "Vertical Collapse?" I would love to save the TV. Hi nothing to worry just minimise brightness to avoid screen burn. "Vertical Collapse?" means one bright hor.line in the middle of screen. this problem can be solved 1 check vertical yoke connector or wire loose 2 check supply to vertical section which normally comes from EHT transformer check components in vertical section or print loose regards thanks

The vertical output IC or the vertical circuit is whats at fault. its all solid state and im sorry to tell ya that its not a user replaceable part. This set is probably not worth the repair it would take to get this set working again but please if you like ask a ;ocal repair shop what they thought about this problem.. Good Luck and please dont forget to rate this thread
