Question about Toshiba 32HF73 32" TV

Open Question

White, washed out screen

Never had any problems with this tv until I woke up one morning and turned it on only to see a white, washed out screen with horizontal bars running across from top to bottom. I could barely make out the cable image through the white wash. Same thing for my xbox. Even when I hit the menu button on the toshiba remote and try to adjust the brightness, the menu display is blurry and unreadable through the white wash. The tv is 2 years old and this just happened for the first time today. Any ideas? thanks.

SOURCE: Wide black bar on bottom of screen

I you know how to repair electronics its not a hard fix. The worst case would be the vertical output IC but im thinking th its nothing more then a capacitor in the verticle sweep circuit The average cost to repair this should be around 75 to 125 bucks. Good Luck

SOURCE: I have white horizontal lines about 2 inches at top of my tv

You have some bad grounds on the Vertical IC. In addition to this, in the immediate area of this Vertical IC, are a few bad capacitors. Look for this IC mounted on a large heatsink. It may have seven pins . I cannot remember for sure. I have not worked on this particular TV, so I cannot give you specific locations. But I assure the problem is in this area! If you have some electrical experience you can pull this board out. In this case only the caps need replaced and the IC resoldered. Good Luck and thank you for asking. If you have anymore questions, visit me...Thanks Again! Your south of the border tech!

Can this be fixed ? what is the problem?


What your describing sounds very much like a video board issue some part is not working properly until it warms up. Eventually it will most likely need to be replaced, If you are not sure what board or part is bad, in the long run it might be a better idea to just replace the TV.

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, carefully using your finger find the too hot transistor or, chip; or, use component coolant; spray the too hot component with a component cooler repower the TV, until the screen comes back to normal. To fix: apply white sylicone 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.

I have owned an emerson tv for two years now. All of a sudden the picture has become very blurry and white. It is not the cable connection and a DVD is also white and blurry. Even the input channels are...


you must open the back cover of tv, and then things you should do is set "SCREEN" adjustment on the flyback transformer. you must turn it counterclockwise to reduce and decrease the level of screen brightness. turn screen adjustment gradually until the horizontal blanking lines disappear from the screen. and blurred images will be sharp again

Vertical lines across my entire screen


My 42" Samsung Plasma HDTV HP-R4252 has a 2" vertical strip of green pixels down the right side of the screen.

My 3 year warranty with Circuit City expires in Nov 2008.. so I hope I'm covered.. can't call until the morning.

Samsung said it might be a logic board problem.. but they want almost $2000 to fix. I might as well buy another TV if Circuit City can't fix it.

Screen problem


this may be a problem of a loose component, looking through the main board and soldering loose components, IC, transistor, all components, just have patience, this may solve the problem.
