Tube tv problem with picture

That tv has no tube, and if the screen is bad it will cost more for a new screen than the whole tv cost. Yes you can replace it but it's not worth it, I would have someone look at it as it might just be an inverter problem.

Hi maybe you heave ghost picture of some equipment what you heave ketch on tv set like a pc or dvd recorder or you heave a problem with a signal board it not switch of inputs on your tv

Yes,now turn on the tv started fading out with white lines on the tv CRT-(tv tube) wright?Tv still have audio sound wright?Tv set have cold soldering joints on it tv video board socket holes joints back of the tv video board connections between CRT-(tv tube) and the tv video board.U have some tools like a soldering iron and a role of solders and u can do basic soldering work wright?Take the tv aparts and resolders the back of the tv sockets holes joints of the tv video boad for a good connections between video boad and CRT-(tv tube).Or take to the tvs shops tell them this,if they're not try to cheat u they charges u like $30-35 take the tv aparts and resolders the tv video board back sockets holes connetions joints between the tv video board and CRT-(tv tube) for u.The whole jobs don't take more than 20-25 mins.

Without seeing the lines I can't be sure what your set has wrong, but here are a some possibilities:

If the lines are lines are confined to the top inch or two of the screen and the picture looks otherwise normal, the trouble is bad capacitors in the vertical output circuit. Fixable by replacing the bad parts.

If diagonal lines are across the entire face of the picture tube and the picture looks washed out, the trouble is often a bad capacitor on the 200-volt line to the picture tube. This may be on the main circuit board near the horizontal output transformer, or on the small circuit board plugged onto the end of the picture tube. Again, replacing the bad capacitor can fix this.

If your TV is actually an RCA, someone may have bumped a rear-panel adjustment. On the back of the TV near the bottom right are two small knobs. RCA left these adjustments exposed inside of putting them inside the set like other manufacturers. These sometimes get bumped if someone was behind the set cleaning, or if a pet got back there and hit them with a tail. The top knob adjusts focus, and the bottom knob adjusts something called G2 or screen voltage. If this gets turned up too high it can cause the faded picture and diagonal white lines. Turn the adjustment down until a black screen looks black instead of gray.

A bad picture tube or horizontal output transformer can also cause lines through the picture. If this is the case with your set, it's time for a new TV. The transformer is relatively inexpensive but labor costs aren't, and the repair bill may exceed $200. If the tube is bad, there's no point even considering repair. The tube cost alone exceeds the cost of new TV.

Hopefully your lines are easy and cheap to fix. Good luck, and thanks for using Fixya!

it is most likely normal--first generation HD sets were 4X3 which means picture is either small left and right or top and bottom; sets which have 16X9 offer full screen HD

Screen Burn Removal Using Your PC.
If you can hook your PC up to your screen burnt TV try this. Create a folder in 'My Documents' called 'Screen Burn'. I'm not joking keep reading. Now open up a picture editor like 'paint' available on all Windows PC's. When you run 'Paint' a blank white document is what you should have in front of you. That is exactly what you need. Select File – Save as and name your picture 'white'. Be sure to save it in the folder you just created.

Next you need to click on the 'black' section of the colour pallet at the bottom of the 'Paint' window. After you have selected black click on the 'Fill' icon (a tipped paint pot) on the left. Now simply click in the middle of your white picture and it should become totally black. Select File – Save as and name you picture 'black'. Again be sure to save it in the folder called 'Screen Burn'. You don't need paint any more so you can shut it down.

Now right click on the Windows desktop an select Properties – Screen Saver and using the drop down list select 'My Pictures Slide Show'. Now to configure the slide show. Click Settings and configure as follows. Slide the bar to 'More' so that pictures change frequently. Slide the next bar to 'Larger' so pictures fill the whole screen. Now click the 'browse' button and find the folder you made called 'Screen Burn'. In the next set of options:- Check 'Stretch Small Pictures', Un-check 'Show File Names', Check 'Use Screen Transitions' and finally un-check 'Allow Scrolling Through Pictures With The Keyboard'. Save the options.

Different versions of Windows might have slightly different configuration options but as long as the result is a completely filled (no borders), alternating white and black screen with no writing then it will probably help.

Now set your screen saver to 1 minute and leave the keyboard and mouse well alone.

As with the 'snow' and 'signal pattern' leave this for a while to see some results. If you use your TV for the PC then it might be a good idea to use this as your regular screen saver and run it frequently.

The only snag is the headache of connecting the PC up and the fact that removal technique will not be running at your screens native resolution.

I got rid of the tv.

First of all you need to find out which CRT leaked and replace it before any other repairs are done. The clear liquid is conductive and has done damage to the CRT board or boards.

key2life316,
Your TV has a bad picture tube = no reasonable repair possible......time to go shopping!....................T.

Guest,
Your TV has a bad pix tube + a blown power supply!!
Time to move on ........T.

Most likely, this is a problem with the convergence board. The convergence amps (STK392-040 x 2)are internally shorted. These can be replaced or the whole convergence board can be replaced. It's cheaper to replace the amps, but more convienent to replace the board (especially for the less electronically inclined!! :) Also, this could be from a leaking CRT. In CRT projection televisions, the red, green, and blue tube are filled with coolent (glycol). These 42" models are very bad about the tubes leaking (Akai and Samsung models)and are infamous for destroying the CRT driver board connected to the bottom of each tube. When this happens, the protection circuit kicks in and will not let the television start up. *PLEASE, FOR YOUR OWN SAKE, DO NOT FOLLOW THESE NEXT STEPS IF YOU HAVE NO UNDERSTANDING OF ELECTRONIC EQUIPMENT!!!! There are four screws and three snap clips that hold the bottom on. UNPLUG THE TELEVISION, remove the screws and pull bottom outward to remove. The bottoms of the three tubes should be visible. DON'T TOUCH THEM!! Now look under each tube. If one is leaking, there will be a wet spot (or sometimes a puddle!) underneath the tube. This will have to be serviced by a TV tech. Hope this helps...
