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

Sony Trinitron TV now taking around 5 minutes for picture to appear (sound comes on instantly) Is it worth repair or should I cut losses and replace set?


How old is the TV?
Sony Trinitron sounds like it may be from the 1980's?
Some TV engineers can use a piece of equipment to do a "tube boost" but this is sometimes risky and can completely ruin the tube, but it's a risk you would have to take.
If the TV is over 15 years old, and has been used regularly, (like 4 hours every day or more) it seems likely that the tube has reached the end of life.
TV cathode ray tubes are like light bulbs...they do not last forever!

Colors Faded in my sony KV-HA21M83A 21''


Its magnetic effect on picture tube. Power Off TV for 20-30 minutes then turn it On, hope problem will be resolved. Please also check and remove any speaker or some thing have magnet near by TV.
If color spots are still there, picture tube need to degaussed / demagnetized.

Sony KV-30HS420 turns off all by itself


This is less a solution than a work-around, but it does work for me, and it is free or low-cost.

I have had the same problem on the same Sony (model KV-30HS420),picture fading out to green then black, then turning off by itself,after which sometimes the light blinks 6 times, other times it blinks 7times. This started about four years after I bought it, which is not adecent lifetime for a CRT TV. It would happen anytime from 2 or 3 timesan hour to 30 to 40 times an hour. After getting absolutely nowherewith Sony, which was completely unresponsive and unhelpful, and which refusedto stand by their product or provide any useful information, I wasgetting ready to buy a new LCD TV, any brand but Sony (never buyanything from them again), when on a whim I decided to try one last stopgap solution.

I put a fan up against the side of the TV, blowing into the vents. Ithas been 3 days now, and not once has the fading and shutting downoccurred. So it looks like the fading out and shutting down wassomehow related to heat, and the ventilation seems to have solved it. I don't know why it should be a problem now, when it was not the first fewyears. It is also a mystery why Sony has not been able to figure thisout, since it is clear from online postings that many people have thisproblem with this model. Give this a try and see if it solves theproblem for you.

Picture goes on and on constantly


I have the same problem. Picture cuts out completely then back on. When I first turn it on, it does this constantly for about 15-20 mins, then about once every 30 mins or so. The sound is fine, but the picture just flashes on and off.

The color is also starting to shift a lot and cannot be fixed by adjusting COLOR-BRIGHTNESS-PICTURE in the video control menu system. Nothing seems to correct this. I've even unplugged the TV over night to see if it needed some sort of reset. Model = KV-20FV12. Purchased in 2004

My connection is a direct cable connection - Comcast cable. Same problem persist while showing a DVD as well.

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.
