My Toshiba I don't have a remote my TV and it stock on channels 3,4,5 My model is 27a45 I got a Toshiba remote but it not working at all I don't know what to do


I do not know your TV type but there may be a few answers.
You say that you have a Toshiba remote but its not working?
Is this the correct one for this model?
Or has it laid around near the TV because it did not work and left?

I say this because a faulty remote with batteries in is very bad if a set can "see it" because it may send pulses out which a TV may act upon without you being aware, I would remove batteries from a remote in a faulty condition for this and other reasons.

Having said this my thoughts for your problem may be its been set into Favourites mode which a person has selected certain channels to be more easily selected.

Another old system I am aware of was during channel setting would be to engage Skip Mode for certain channels to "leave them out" (to stop certain ones being viewed by children).

A further problem might be that your set has developed a fault which will require possibly an engineer to look at.

Cures for it :- well the first two would possibly require a working remote and instruction book to check out the above points I mentioned, as for the last this may require you to Reset you TV back to an original state again, this will reset its software and possibly cure it. This would be found in Menu-Setup area of its menu.

Hope this gives you some help.........

With no stand by light, you are not getting power.Unplug TV and check fuse on power supply. You will need a meter to look for shorted components and possibly leaky/bulged capacitors that are killing your power supply. flickering could be part of the bad power supply or possibly a problem with YSustain area of your TV

This is a common symptom of tuner trouble. A common problem is bad solder connections inside. As the set warms up, small cracks on joints from the tuner circuit board to its metal case can cause the trouble you describe. If you tap on the TV or wiggle the connector where the antenna or cable line goes, the picture will sometimes pop back in if this is the case. It's also possible the tuner has parts that quit working as they warm up. The only way to know for sure is to remove the tuner, check over the connections, repair any that are iffy, and see if the trouble continues. This is not a repair for a do-it-yourselfer, though, because of the soldering involved.

If the trouble isn't bad connections in the tuner, there's not much you can do. I've checked the parts sources I use. The original Toshiba part is no longer available and I haven't found any replacement. If you're using a cable box or other video source, you can keep using the TV just for its AV inputs and not worry about the tuner any more. Otherwise, given repair labor cost and lack of parts, it's probably more economical to replace this TV instead of trying to repair it.

Hi i have a 42" LG lcd tv .When i switch it on


the inverter for the backlight likely has a bad capacitor or more. The fluctuating high voltage is causing the jumping and eventual blackness until sufficient charge is on the caps, at which point it stabilizes...it eventually will stay black unless the caps are replaced.

When turned on, the screen has waves in it across the top and flickers. It is unreadable. When the TV warms up it seems to be better but is starting to flicker or flash all the time now.


Hi,
Your Toshiba TV has hyperboard inside and there are few electrolytic capacitors (may be 10) that need to be replaced.
If you are comfortable with soldering parts in PCB then go ahead or ask help to any friend that knows electronics stuff repair.
Let me know further query.
Thanks.

Picture often flickers and image distorts every few minutes


The trouble is most likely in the Video processor. If the trouble looks like its tearing the video only from side to side it may be the line doubler circuit. Some of these boards are no longer available but a good TV tech may be able to componnent level repair it for you.

DLP TV starts to loose picture after 1 - 1/2 hours of use


This tv has a 3 board video path. Analog main pcb --->Digital main pcb --->DMD pcb. see which inputs have the problem to narrow it down. if only some inputs, suspect analog board. if everything flickers(all inputs and menu), suspect the dmd or engine. you can see the lamp shine out the back. if the lamp is flickering, suspect lamp or ballast.

Flickering - Toshiba 62HMX84


it could be as simple as the tv feeding back on itself in a dark room.
it is adjusting the light level because of what it sees ambient in the room.
turn on a light near the tv and see if it stays constant now.
