My picture is all scrunched up in the middle of the screen,black on the top and bottom,otherwise the width of the screen is fine! Is this a picture tube going bad or just an adjustment?

There's trouble in the set's vertical output circuit. Often this is because of bad solder connection, but there could be parts that need to be replaced as well. It isn't the picture tube going bad, though, so the set could be fixed. (Actually, even a bad picture tube can be replaced, but when the tube goes it's cheaper to buy a new TV!) Often just resoldering the connections in the affected area brings the picture back to full height. It's not unusual for capacitors in that area to wear out with age, but they're inexpensive parts.

The trouble with TV repairs is the labor cost. If you don't know anyone who has the skills to check over a circuit board and do electronic soldering, and to check and replace parts, you'll need to have a professional do it. The total cost of repairing a small TV might make it worth spending a little more on a new flat-screen LCD. They've really come down in price.

Most shops charge a fee (applied to the repair if you go ahead) to check the set and give a repair estimate. If you don't mind the gamble, get the set checked. Otherwise, start looking for a good sale on something new.

I have a rca tv model #27v5137 that only has the bottom picture displayed. Does anyone know what is wrong with the tube?

It is not the picture tube but is a vertical deflection problem. Usually it is a capacitor C246 and this is the location number and is a .47mf And at the same token bad solder connections on the pins of the vertical deflection IC301. Soldering the pins of IC301 is likely to fix the set.

1) I have a Sony KV-32FS13 that has a green tint in the picture. Does any oneknow how to access the service menu for this model? I tried other adjustments and I can't get rid of the annoying green...

Code 5 is "AKB error". AKB, or auto kine bias, is a cicuit that monitors the three color guns of the picture tube (red, green and blue) and tries to adjust them for proper color balance. If it can't, the picture is blanked (usually) and the timer/standby light blinks 5 times. When the color drives aren't balanced, you see a color tint in the picture like you're describing.

There might be a problem in the AKB circuit, or the picture tube may just be old enough that the AKB circuit has run out of adjustment range. If the tube is at fault, you should consider replacing the set. A new tube will cost nearly as much as a new 32-inch LCD TV, and you'll need to pay someone to install it and set it up. There are special tools required to perform the convergence which gets the color guns aligned with the face of the tube so they hit the right colors.

If you'd like to try tinkering with the service menu adjustments, this site explains how to access the menu and gives a list of settings.

Need picture tube replaced for rca television not

You have to get the exact type no. of the picture tube. Better buy a new TV. Picture tube will be expensive and no guarantee whether it will have sharp image l after replacement.

Picture tube

If your tube has gone and you are looking to replace it - my advice is don't bother - it will cost you dear in the end. The best thing to do is try to get another CRT TV set (maybe a different make/model).
It is a skilled job replacing a TV tube and should not be attempted by anyone who does not know what they are doing!!! In the wrong hands a CRT is dangerous and could cause serious injury if dropped or handled incorrectly (it makes one hell of a bang).
I wish you luck with it all the same (:-)

Toshiba 32A41 TV -- color problem

Toshibas are notorious for developing shorts in the inernal guns of the picture tube. In your case the green gun is shorted to G1. The noise you heard was an internal arc between the elements. It is unfortunate however, the repair of this problem usually requires the picture tube to be replaced. Sometimes a savvy technician with sencore picture tube rejuvenator can remove the short. This however usually does not last. Scrivitron

A "Gray Scale" adjustment may solve you problem. If one of the picture tubes is set too high it will cause these RETRACE lines. Then too a weak picture tube might cause this. If the horizontal lines are one color: red, green,or blue then whichever color that is shown would tell you which tube is set too high. Your set has 3 screen controls that control the brightness of each tube. One may need to be turned down a little. Stargazer

Tv shuts off - sony kv-32v40

They are very relevant because you might have a high voltage ark from the output transformer or a shorted picture tube,the ark or high voltage leak you might not see but the shorting of the picture tube you will when it does it,being careful remove the back cover and leave the back open,turn the tv on and wait for the moment the shutdown takes place and look at the neck of the picture tube and thru the glass of the tube you might see the moment it shorts out and the set shutsdown,if you see something in the neck of the tube is because the tube is bad,take a look at the conections in the crt board maybe one of them is loose,the arking or leakage from the output transformer is dangerous and it should be observed from a safe distance(10 feet),if you notice something in the output transformer he will need to be replaced,both situations involved high voltage areas and if you are not too familiar with tv service you should get the assistance of a servicer.It is a good idea to resolder the main board if the two possibilties do not show or when the main problem is corrected.Let Us know how it goes or if you need more information.
