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.

Picture on my Toshiba 37RV753B has gone off and the standby light keeps flashing yellow. It was working ok a few hours ago, but I switched it off to go out and now it won't work. It's only just over a


Hello!
If you have used your TV 24/7 for the past year, the issue might be in the power supply. If there are "bloated" capacitors, set will not start up. If you haven't unplug it for a year, it might be staying alive. Once you unplugged the set, those capacitors won't let your set back to normal. That's a big project and requires technical background. If you think you can handle that, open your TV set and inspect TV's power supply board. It will be located near power cord plug or wire. Also, it might be covered by tin shield, which must be removed for further observation. If you see any "bloated" electrolytic capacitors, replace them with same value and voltage. But it might be main board's issue, as well. what is your place's ambient temperature? If it's lower, than 75F, try to warm up the back of the set, before even trying to poke it open. Use hair dryer. First, point it on main board's in/out connectors. Do not overheat! Few minutes might be enough. Then, try to plug the set in and observe the behavior. Any change? turns on? Main board is bad. Same with power supply. If heating up main board area does nothing, try power supply area. If it makes a difference, start looking for bad capacitors.
Good luck,
Let me know results.
Thanks,
Alex.

TV comes on, but shuts off after 3 minutes. I must wait at least 5 minutes to get it to turn back on again. TV will ONLY stay on if DVD drawer is OPEN!


dvd is overheating its circuit. Keep the tray open to dry up condensation. then leave TV on standby to keep moisture out.

(i) Disconnect all the cables from the TV including the power cable then reconnect them after a few minutes.
(ii) Make sure that the power cord from the TV is directly connected to a functional wall outlet.

If the standby light keeps flashing then service will be required.

I have a toshiba tv that turn it self off after few minutes


Is the tv getting too hot and shutting off? Vacuuming will help get the dust out of the fan but inside the actual tv there may still be dust blocking cooling.

The TV switches it self off


Sorry to here about your TV problems but it is almost imposable to help someone with technical problems if they don't list a product, model or P/N number.
Either-way, I would try moving the unit in an area where it has more breathing space if poss-able.
Also, is the unit in a air conditioned area or in a Damp basement or Florida room ?
I would also, go on line and see if Panasonic has any call backs on this unit.
This may be a feature which can be reset without to much trouble.
Next time please list the size & model #.
