We have had our TV for four years. We started having problems soon after we bought the TV. Had a repairman out to fix the problem. Helped for awhile. The picture has now gradually faded out and none of the adjustments do anything. We can not fix the problem. Also the whites are too bright and occassionally the faces have green splotches on them. The TV is way too big to transport and we are looking for a repairman that can come to our house to fix it. Can you help? Linda Metzer

Re: Bad color, faded out picture
Typically, overtime your tv will become out of tune.
The way a display TV works is by shooting electromagnetic pluses through a vacuum guided by variations of magnetic stability.
What that means is overtime magnets tend to wear down thus resulting in a repairman call. Unless you are a expert in the field of tv repair i would also suggest for you to call them up and have them come fix it again. Although, though experiences and a budget, if you are able to upgrade to a LCD flatscreen I say do it. It will save money in electricity and the hassle of someone having to come fix your display.
Please post what you do and how you did it.
I look forward to your posts.

The problem is in the picture tube board circuit. Sometimes the CRT socket doesnt connect well to the CRT pins. Or maybe there have bad solders from RGB transistors. check those transistors, Also the bad thermistor discolored the entire tv screen.
I've answered three of these so far, so this problem must be a very large manufacturer's defect big among large-screen LCD TVs of a bunch of different makes.
It's a power capacitor inside the TV that controls whether the power supply works or not. Our Samsung 46-inch started doing the same thing with about 2 months of a 2-year warranty left in it, and I'm glad we called the local retailer, because they were aware of this problem and gave us the number to Samsung, who paid to send a trained repairman about 60 miles to our house to fix it. During his repair, I helped him remove the large back cover, and set the TV on its face, and asked him about the problem. He detailed to me exactly what I said above, and also that it's been a very big problem with the rush to get new TVs out to market.
If your TV is still under warranty, jump on this situation before it runs out--it is a hardware problem, not fixable otherwise...
If it's out of warranty, your local TV repairman should be able to repair this for less than $100, easy (the part on ours was a $2 capacitor, the repairman said).
Hope this helps.
Any luck? We bought our tv (same one) in March of last year. It is doing the exact same thing. Time Warner has already came out and switched out the cable box and cables. We have a tv tech coming soon (contracted out from Samsung, of course...) Problem persists...
It depends on what the problem actually is; are the streaks colors like red or blue outlines around lettering etc?
The more you tell me the better I can help. I will post a photo or two of what convergence problems look like. This set is also prone to another problem, on a blank video input look at the screen: you should only see Video 1 (etc) and if you see faint curved lines (red, green or blue) and or the back ground is also wrong color you have the second problem.
let me know which it is.. If this information helped you rate this solution as very helpful as I do this here for free.
if it is a tube type unit you may not find a new tube they are almost extinct ,
also, most tube malfunctions are caused by improper voltage, only a qualified tech should work on the high voltage section of a tube tv,,, it can kill you even if it has Not Been Plugged in for a whole year
re-post with the make and model number for further assistance
This sony (KV-36FS120) is a flat screen CRT type Television not LCD. However the problem you are describing sounds like a CRT problem. I posted this before and I hope it is helpful to you,
This may be a CRT problem. From what it sounds like i.e. dim picture,
colors not bright. If you have a background in electronics I would tell
you to check the voltage levels on the CRT pins and compare them to the
values on a schematic, however if you do not have a background in
electronics, I would suggest you taking the TV to your local TV repair
shop and have them troubleshoot your problem.
Here is a possible list of things that might be wrong:
1) CRT going bad (The shop can try CRT rejuvenation if needed) 2) High Voltage on the anode not at proper levels (The shop can check this with a HV probe) 3)
Video output levels low (The shop can check the voltage and signal
levels on the CRT socket board, and on the video amplifiers).
