After turning the tv on the colors are reddish and slow to conform to the normal color tones. i have a 36" toshiba flat screen tv


My first concern would be that, the picture tube is going bad. The problem you describe, tell me one of the color guns is shorting. In this case I would think the green gun is shorting. There are three color guns in the neck of the picture tube. They are red, green, and blue. Most of the time the green will short as it is powered heavily in most TVs. The next thing to check, is the small board connected to the picture tube. Look for any and all bad grounds on this CRT board. This is another big problem in all Tube type TVs. On this small board there will be three color output transistors, and resistors. These will many times run very hot and will create bad grounds over time. Check and resolder as necessary. If the CRT board does not fix your problem, replace the TV. Picture tubes are very expensive and will not be feasible for replacement. Search for a new TV. Thanks for asking and show all hands of support!

The picture has lost focus and lost green


hard to say for sure, but the front opens up when you remove the bottom or edges. inside you need to inspect the CRT boards for any fluid leaks. there are focus adjustments on a black controller with 3 knobs on it. I would say take a look at the middle tube (green tube) if its dark and the circuit are dry. Try cleaning the CRT pins with the TV off, simply pull the cba/socket down and push it back up.
so lets see no green tube lite , cleaned pins no fluid, next tap it to see if it flashes bright, no OK now on the grn CRT circuit board slowly TV ON turn up the control you see and see if the green gets brighter. The CRTs are fluid filled and the fuild can get cloudy causing it to get dark and blury too. to check the fluid you would need to pull the screen off (a real pain)
these steps will help you isolate the isue and decide what to do next, hope this helps

Poor pictre quality


This set has 3 CRT's (picture tubes)
Remove the back bottom cover
Clean the CRT's with windex and a soft cloth.
(Find the Screen/Focus block)----Remove front grill cover and panel which covers the Screen/focus block.
Cover 2 crt's and adjust the focus control for remaining crt---(using the convergence pattern in the menu for the set)
adjust for the best focus.
cover that crt and move on to the next crt using the same procedure.
After setting the focus on all 3 tube's you will have the best focus possible for this set. If picture is still bad, you have bad crt's and the set is junk.
Cost to replace the CRT's is enormous!

The picture on my Sony KP57WS500 is starting to fade to blue after being on a short period of time. ANY IDEAS?


Good Day;
A blue picture after it's been on for a bit is normally one of several things. The most common for your Sony is the CRT, tube, the second most common problem is the blue CRT 'IC'(chip). The IC is located is on the blue crt board.
The best way to determine this is to remove the speaker grill(on front of TV), then inner panel, the blue tube will be on your right hand side. Remove that little board at the end of the tube.THIS AFTER YOU HAVE UNPLUGGED THE POWER FROM THE WALL. Plug TV back in turn TV on. If TV comes on with picture and there is no blue in the picture, The tube is bad, if TV turns off it's the IC.
Good Luck, BI.

Have you tried to access the menu features and tried to retune the stations on digital, or are you hooked up for analog.
If you don't know about what i speak, give me a yell. [email protected] I believe my remote sensor card is bad. While this might explain why you can't turn yours off, it would not explain the blank picture. If the menu does show, i would think the picture tube is O.K. if the menu does not show, there are some other things to look at.

Sony big screen tv not playing picture after 5 minutes or so


You have a bad picture tube, or perhaps a picture tube drive problem.. To see what is bad, remove the front speaker grill under the screen in the front. Remove the screws that hold on the board that covers the front. Insidfe this set, WITH THE TV SET UNPLUGGED< Locate which one of the tubes is the blue one. Gently pull off the board from the end of the picture tube and swap it with the green tube right next to it. The green tube is always the middle tube. If the blue comes up again, then the blue tube is bad and you will most likely be better off to buy a new TV set. If the green comes up as the bright one, swap back the boards, call a tech and tell them there is a CRT driver board , or an RGB drive problem. This should not cost you an arm and a leg to get repaired. Good Luck, and let us know how you make out with the repair of this TV set.
