    When switched on my 8 years old Philips Model 21FT240B / 94 R from cold, it works for about 10 minutes and then the screen shuts off from the left side and then switches off. Red stand-by light flashes continuously. I have to go and switch off the TV Power Switch / Electic Plug switch, to turn the TV Off completely.Then after, say 1 or 2 minutes, if switched on, for about 3 to 4 minutes, it will work, and then again it switches off as mentioned above. Any solution ? Or do I have to change the TV and buy a new one?

Good day.
This is a common problem for all television however, for us to isolate the concern better, we will need to have the model and brand of your unit.
Ussually, this problem is associated with the vertical circuitry. It can also be traced on the low power supply section such as the system or chroma ICs'.
Response is higly appreciated.

I have a sony tv model kv-27v42 i have sound but no pictture and stand by light blinks what is the problem


How many times do this standby light blinks at a time of switch on? These blinks are fault indications. From the number of these blinks, you can get an idea about the faulty circuit section inside it. Count it. If you wish to get more details about the blinking codes to Sony TVs, check this link.

Need the code to set the technika remote to ma toshiba telly


Maybe you could try the auto-set. Found this using google:
Auto code search

1. switch on the TV and select a channel eg. Bbc1 on the TV itself
2. press the appropriate device button eg. TV
3. press the green SET button for approx 5 seconds until the red light comes on.
4. release the green SET button and point the remote at the device to be controlled, the remote will emit a test signal about every 2 seconds.
5. when the TV switches itself off briefly press the green SET button to store the code found.
6. when the red light goes out the search is ended.
7. try out the remote if it works follow the same steps to set it to other devices eg. DVD. If it does not work follow the steps again.
cover other remote sensors on other devices when setting the remote.

sounds lick you may have a dry joint in the powers or line o/p stage.

as a rare fault it could be the crt with an intermittant internal s/c. but you would notice the colour was tinted either red, green, or blue in the dark areas of the pic.

Try to remove the vertical IC sometimes it become Shorted causing the B+ to drop. after removing try to switch on back check the B+ if ok and the LED not blinking then change the vertical IC.

On older Sony, sometimes a power surge causes the set to be in shut down mode. Try unplugging for 5 minutes and then plug in and try. This many times will fix.

Sony kv32fs16 problem


The STANDBY light is flashing on the television and there is no picture or sound. Solution
sp.gif sp.gif The STANDBY light will flash if an issue is detected within the television. This can sometimes be resolved by simply following the steps below to reset the 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.
If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center.
