Hello oilreddye,

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).

These are the three primary possible issues.

I hope this helps,

Thank you,

Shuttle83

My Samsung TV color fades out after about 30 seconds.


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

DARK SHADOW EFFECT UPPER CORNERS OF SCREEN


I would check for dust particles before I attempted any type of repair on the unit.

Dust particles will appear as dark spots that are larger than the size of an individual pixel. It must first be determined if the particle(s) are on the LCD panels or the screen.

32''LCD TV Polaroid FLM-3201 - picture crackling and color fading


Sounds just like a loose solder connection. The trick is finding it. I would start with the microchips and the large transformer. Otherwise, it could be a capacitor starting to short out. I would give both options a 50-50 chance to be the problem.

Poor picture quality from 130 degree viewing angle on my LCD tv


It is unfortunate but "off angle" viewing will compromise the picture especially on larger TV's and LCD. Off angle viewing can come from the vertical axis or the horizontal, as you described. This is clearly illustrated with a laptop computer. Adjust the screen forward and back (vertical plane) and you will see very clearly that you get the brightest picture in a very small amount of range of the screen. Likewise, viewing from the side compromises picture as well.

I also don't believe that the delay is indicative of any problems.

Delay to see the picture


Your power supply is going south, I have an old sony with the same problem. The voltage level drops and does not have enough 'kick' to start. It will work better when it is warm. The module will need to be replaced.
