The vertical scan output stage is faulty. Check and replace damaged component/s in the vertical output circuit. Visit the site named 'Electro-help' for more details. Click this link.

SOURCE: Proscan PS35123-horizontal line only,sound ok

You have whats called a verticle swep falure. Its probably just the verticle output IC but if you dont know much about soldering or circuit troubleshooting ,you should leave this to the pros. Theres way to much Hi voltage inside these sets to twiddle around inside them. Also there are no consumer serviceable parts inside these sets as well, as they are all solid state, and my advice is spend a few bucks and get a pro to do this job for ya, as it can, and will, kill ya if your not careful.. Is it worth saving a few bucks??? Naawww Call a pro.. Good Luck

SOURCE: Top 2'' has tiny horizontal lines

Your symptom sounds like a faulty capacitor in the vertical deflection circuit.
What you are seeing is called vertical fold-over.
If you want to fix this yourself and are handy with a soldering iron, it is not that difficult. Just look for a 1uf capacitor near the vertical IC. The vertical IC will be a black IC with straight legs mounted to a heat sink, generally in the center of the circuit board.
Note: Be careful when working on a television as the CRT and other capacitors can hold a charge that can be very dangerous.

I would recommend that you contact a local service center and see if you can get a quote for the repair. I would normally charge between $120.00-130.00 for this type of repair. The cost may vary depending on where you are located.

I hope this information allows you to resolve this issue.

I have a horizontal white line has been appearing recently on the bottom of my lap top's screen, i have not installed any new software and it hasn't fell down like ever ... what's the solution...


Hi,

Just boot to BIOS (either by pressing Del, F2, F10 (depends on the laptop brand).. upon turning on the unit). If the white lines appear, your problem is with the LCD screen.

If no white line in BIOS, install an updated driver of your video card. However, if installing the driver doesn't help, your video card is faulty.

Hope this helps,

Horizontal white lines 27A43.


You have some bad capacitors. They are located very near and next to your vertical IC. I would guess you would have to replace maybe four of these! Thanks for asking!

Toshiba colorstream 27A33 TV


1.Are these lines only in the upper 1/3 rd portion of the screen?And is there a clear demarcation between this area and the lower portionb, where the image is perfect? 2.Or is thin Horizontal lines evenly spaced around an centimetre apart? If it is the first case, then there si a problem with your TVs SMPS. It is not generating the required regulated 110V required for the TVs functioning. If it is case 2, then there is a simple adjustment at the back - 'SCREEN'. This adjusts the Screen Grid Voltage, and by slightly lowering it, this problem will go away.
