Try using the remote to select from normal to widescreen or zoom. Thing may have changed with the switch to digital only or you may have to rescan all the channels.

Ihave a 20INCH Sharp LCD TV,No picture only colored lines.Is it worth fixing or does this indicate the picture tube is gone,thank you


to start with it is an LCD screen so it will not have a tube to fail
next take it to a repair shop for a quote as it could be a picture board and a simple repair
make you decision to repair or replace from the cost of the quote

I have one pink, one green, and one yellow spec of light almost directly in the middle of the screen. How or why did this happen and how can I fix it?


This set (model indicated) has 3 picture tubes.

I suspect it arced or popped and all three now have a burn mark causing this problem---simple way to prove it:

Remove back cover and cover one of the three large lens(green is middle one) and turn set on----if one of the specs is gone---that tube is burnt---cover lens one at a time and each will vanish.

BAD NEWS----cost to remove/replace all three is too much--AND SOMEONE WOULD have to find and repair the problem that caused it or it will just repeat it again.

Let me know if you have questions.

From your description the picture tube has gone, and usually it will crack where the filaments light up, once air gets in the vacuum seal is compromised causing particles to fly damaging the delicate phosphor where the picture is generated. The replacement of the picture tube will far exceed the cost of a new tv.

I have an old 36 inch widescreen Philips CRT TV which has been working fine for 7 years until yesterday when the whole screen just went blue with a series of white horizontal lines. The audio is still OK...


Hello
Since there is a blue screen atleast, I don't think that the picture tube is gone. The fault may be either to its chroma IC or video output section. In both sections fault cases, this type of horizontal lines [parellel to each other at about 1 inch or so apart the entire screen] will be seen. Just check the voltages at the three cathode, ie, red, blue and green of the piclture tube. This can be measured at the picrture tube neck card. If you have through knoledge in electronics, have patience and enough tools to do the work, inform me through Fixya. Without these, you can't work on a tv, especially in Philips.
Otherwise, get it checked by any expereinced service technician. OK.

No picture.Just a single line in middle of screen.


No, your picture tube is fine. This is a problem in the vertical circuit that deflects the beam up and down. This repair is fairly typical across most television brands and should not cost too much to fix. I don't want to quote another shops pricing but from us this would run about $150.00 to fix.

Picture is only in middle of screen, top and bottom of screen is blacked out


If you are watching widescreen format movie or tv programming on a non-widescreen tv, that is how it will appear. The widescreen is a wider picture so to show it on a less wide screen, it has to shrink down to fit. and leave blank space top and botton.

If not, sorry.

Picture's gone--sounds fine!


This is very likely not the picture tube. I suspect that something in the vertical oscillator section has gone bad. You will need to get the schematics for this set. Locate the vertical section and look at the transistors and IC's to see if they are still good. Also check for bad solder joints and open resistors. You can do all the checking with a simple Digital Volt Meter. You can get all the info you need online for how to test transistors, diodes, electrolytic capacitors and resistors. Most of my TV fixes have involved bad solder joints that have gone bad after years of hot/cold cycles , usually under a component that gets hot (heat sync) , resistor, or heavy item such as a transformer. The other issues are usually with transistors or IC's that have gone bad due to power surges or age degradation. Sometimes fuseable resistors open open. Sorry I can't be more specific. There are too many things to check. Could also be a power supply issue. but highly unlikely if you still have a center line. TV tubes hardly ever go bad unless the set is very old.

1) The 4:3 / 16:9 option only optimises playback for that particular type of TV. The 4:3 setting also allows you to set the output between:

  • 4:3 PS - expands the picture vertically and horizontally which gets rid of the black bars, but you also lose the left and right edges of the picture.
  • 4:3 LB - Letterbox format, displays the full picture from the disc, with black bars top and bottom.
The PS option loses the bars on 16:9 widescreen DVDs, but may still leave bars on true cinema widescreen DVDs, which are 21.7:9
This is normal.
  • 16:9 - Optimises the picture for a widescreen TV. Again True cinema widescreen DVDs will still have black bars.
2) All of the external inputs will show "No signal" until there is actually a signal playing into them.
EG to copy VHS to DVD, you will need to select the relevant scart or phono input, and press play before the recorder will register a signal and allow recording.
Some bought VHS videos have copy protection, and may cause problems when copying to DVD.

3) Greenish playback maybe caused by colour setting on TV being too high. Also check Hue or Tint settings on the TV, if it has them.

4) For some reason, in their infinite wisdom, Philips omitted the Video Plus facility from this model.
