The red light on the front of the TV blinks all the time. No sound or picture. It is a Sony Model KV-21s65

The TV will cause the STANDBY light to blink or flash when the TV detects an issue.
The number of times the STANDBY light flashes corresponds to a specific issue.

If the TV is plugged into a power strip or a surge protector, please remove it from the power strip or the surge protector and plug it directly into the wall outlet.
If the issue is resolved, the problem is with the power strip or surge protector and not the TV.

Also try connecting the TV to different AC wall outlet and check if that helps.

If the issue persists, the TV needs to be Serviced.

The set will need to be serviced to allow a technician to determine the specific issue that needs to be repaired.

Please contact the local Authorized Service Center to get the TV serviced.

Color problem

Sony TVs has an Optical Block issue. If there is an issue with the optical block, then there will be green, blue patches or tint on the TV display. Try resetting the TV to the factory settings and try Power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue still persists, then TV may require service. You can contact the Customer relations team and check for the available options. Sony had repaired free of cost for such issues. Hence, contact the customer relations.

Tv clicks on but no picture yhe stand by light is bliking i have unpluged the tv from wall and the cable box but it justs click when you turn it on no picture could the settings be on

Hi .

The clicks that you hear is an internal device called protection circuit that is shutting down the TV, and forcing the PSU to +5V low only to keep the TV in standby.
That is called protect mode.

If the TV stays in stand-by, with the LED light on, but does not respond to remote, or to the buttons on the chassis, then that means that the TV has gone in protect (safe) mode because an internal fault had been detected.

In that case the TV is usually faulty.

The fuse on the PSU board is not causing protect mode. When the fuse has blown , then the unit stays completely off.

Common faults on rear projection models are Electrolytic capacitors on PSU board (power board), convergence ICs (convergence board). The parts must be tested before replacement. Less common faults could cause the same problem.

Try first disconnecting all connected devices, and leaving the TV disconnected from power for about 30 minutes. To drain power completely.

You cabn follow the basic troubleshooting on this article: Why my TV does not start up and remains in...

If that does not work, contact Sony, ringing the support number listed on the owners manual to get the TV repaired by a licensed technician.

Watching tv/w a dvd/vhs player(a seperate machine)the power goes out on the screen.went out with a white flash like usually when i turn it on the bottom where the control buttons are,a red light...

It seems that your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur.
You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done. It is that sound that gives it away, this is a typical switchmode Power Supply problem.

TV Zoom mode

Change the batteries on the remote, point the remote at the Sony, and hold in the power button for 5-7 seconds. Then depress and re-press the power button - see if you can get the tv remote to respond again.

Then, always try the quick reset:
How to perform a power reset on a Sony® television.
  1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
  2. Unplug the television power cord from the electrical outlet.
  3. Let the television remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
  5. Turn on the television.

Sony Trinitron Power Surge 5 Blinks

once you have diagnosed the problem, the following link is to all parts for your tv stocked at partstore. they generally have better prices than the dealers and repair shops.
KV-36fs13 parts

you can try the dead-tv kit from fixyourowntv if you have some basic experience with soldering and circuit repair.

Five blinks means, "IK (AKB)" (white balance). The probable causes listed by Sony are as follows:
1) Video OUT (IC561) is faulty (A board)
2) IC355 is faulty (A board)
3) Screen (G2) is improperly adjusted.

not sure what the 13 blinks are for.

hope this helps,
