Picture disappearance & tv turns off

We have a toshiba tv, about 3 years old. Sometimes Tv turns itself off(on standby). When you first turn it on you get sound straight away but takes time for picture to appear.It also loses picture after a few hours and may come back on its own later(still getting sound). We have also noticed strange colours & sizes on screen. It is kept under window (in sun)could overheating be problem?

It sure sounds like you have a classic case of bad solder joints. Resolder all the connections on all boards.

Hi! My toshiba 2100td tv is over 10 years old and last few years it's having weird problems. When it's turned completely off (not in standby) and when I turn it on, the screen blinks for a 10-

The real problem here is its age, a lot of these sets of that age critically needed parts are just no longer available.

I repair them but the real risk is someone fixed it, a few months later it develops another problem etc etc etc.

Ten years is now a days a long life for a TV.

No Picture on Toshiba 42RV530U

I had a similar problem to this yesterday. Tv is same Toshiba model as you mentioned about 4 months old. In my case, after the TV working perfectly following installation, the standby LED on the front (the one that is red on standby and green when on) went to a flashing orange (after switching on from standby) and the picture disappeared although the sound remained OK. I was unable to get any response from the setup or menu on the remote, otherwise I would have tried resetting the TV. Regardless of how much switching off/on (including disconnecting the powerlead and leaving for few minutes), disconnecting all peripherals, etc., nothing helped. I looked up Toshiba's web site and under support they basically suggest switching off the TV and restarting using the onset buttons (not the remote) and pressing the menu button (again the one on the set (not the remote) and if you could get the menu box to appear then reset to default settings. I tried this but the results were the same. I therefore thought the TV was defective. However, after much frustration I did the following (I think): 1) Disconnect everything from the TV 2) Powered up from the mains switch whilst keeping BOTH the startup and menu buttons on the side of the TV pressed down. The result in my case was that the standby led and one of the two beside it flashed green simultaneously. However, when the buttons were released, the TV started up the same (flashing LED orange and sound no picture). 3) Pretty well defeated at this point, after doing the procedure at (2) several times with the same results, I somehow thought of pressing the standby button on the remote either whilst the two buttons on the set were depressed or just after they were released. I am afraid I cannot remember which and cannot replicate the problem as I don't know what caused it in the first place. 4) The TV then started normally ( no reception as I had not aerial connected, etc.,) but I was able to gain access to the screen menu/setup buttons via the remote which were in French rather than English. However, after reconnecting everyrthing the TV has worked fine (obviously after resetting the language via the menu). I am sorry I cannot be more precise but I hope this might be of help to someone with a similar problem.

Sony KDL40S2010 Bravia LCD TV... turns off / on on it's own

If TV does not remain in standby and turns on itself then power switch on top of it could be defective and power supply board is also suspected. Take off its back cover and unplug top switch connector just to confirm is that cause of On-Off its own. If problem still exist then power supply board has problem and will be replaced. Let me know the results to move forward.

this sometimes is quite simple to fix as it cud be a dry joint on the circuit board where the tube motor sits.

or it cud be the tube is on its way out, which wud be cheaper to buy a new tv rather than have it fixed

Check your CRT boards on the end of the tubes for burn spots, and burnt components, check the resistors to make sure they are not shorted, burnt, and they read the correct resistance. Check the diodes to make sure they conduct in one direction only and are not shorted or open.

TV turns off by itself after being on for 60 seconds

Led blinking Three times means B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.
Hope this helps.
