SOURCE: my remote control for my polaroid tv wont change channels.

You may be able to program your cable box remote to control your TV in addition to your cable box. When they initially set up your cable box they probably left a pamphlet giving you instructions on how to program your remote. I'm not sure why you can't change the TV channels manually but this may give you a work-around.

SOURCE: When I turn on the tv the word Polaroid appears

Hi there, I don't completely agree with the previous opinion. The problem lies not in the lightst....he caps (capacitors) in the powerboard are going out. This is a very common problem in all class and price ranges of modern lcd and plasma tv's/ monitor's. I don't know if this problem has been like this for awhile or it just started, but either way, if the tv takes an abnormal amount of time to "warm" up then it most likely will go out all the way sometime in the (near) future. If you have a tiny bit of will and knowledge ypou can open the unit and get to the print board. Examine this for "popped" capacitors, they will have a buldging top instead of a flat one. Im gonna try to include a pic of them here, if i can get it this time, I've tried bfore lol. But you can google image a "popped" or "bad" capacitor and you would be able, with ease, to diagnose if you have any of these. Usually only one or two. Radioshack sells capacitors (couple anyway) for $1.59 each. MAKE SURE the replacement is of the SAME voltage or HIGHER, or you will be right back replacing those 2. Every capacitor has a negative pole marked with an (-) on the side of the capacitor(by one of the "legs", always puit the negative (-) "leg" of the new capacitor in the same hole in the printboard as where the previous negative (-) "leg" of the capacitor was ( a capacitor with the negative and positive "legs" put in backwards will result in the new piece "popping" as sson as you turn it on!!) make sure the "uf" rating (for example the most common popped capacitor is the 1000 uf) is the same as the one you are replacing. I needed 1000 uf, 105 c and 26v (volt) ratings for the 1 capacitor I needed to replace to fix my LG 19" lcd panel monitor I found by the trash that the light came on off, but it didn't come on. I replaced that capacitor with ; 1000uf, 85 c and 36 v (volts0...It works fine eventhough the volts and the temperature rating (36v and 85c) was not the same as the (26v(volt) and 105c ) capacitor I removed !! Further, I've replaced capacitors that had the celcius rating of 105 with the only ones Radioshack had, namely 85 c(celsius) they have been working great, but I'm not sure about any effect, nor have I heard or read (yet?) about that making an urgent difference. Many threads that I've read people have done the same, so we should be ok (my stuff has been running good for a while longer then most brand new ones!.............(all these ratings ; 'uf ' and 'c' etc are on the side of the capacitor you are replacing and on the side of the ones you are replacing them with)...For all this all you need is the cheapest solder gun u can find (I bought one for $7.99 at Radioshack), a camera (to take pictures as you go to remember how to reassemble the unit) and, once you have your materials, 20 minutes to replace 2 or 3 capacitors and you are good to go...Most monitors and tvs (lcd/plasma) I've seen you have to lay flat on the ground/bed/blanket etc, to work on (screen side down). Usually there are 2 or 3 screws (or a few more) to remove, then you will have to carefully (its comes off easily most times)insert a flat screwdriver inbetween the casing and gently pry it up as you go around the whole frame. Sometimes you have to remove the little washer arouind the cable input orso, just be gentle and you cant go wrong. Once insidet here will be a box with wires running to the sides etc...unplug, gently, these wires and open the box. Inside you will find 2 or 3 circuitboards, check them all for "popped" capacitors, replace, reassemble and plug it in....Have fun becoming an overnight tv mechanic lol! If this helped(or not) please rate, thank you!ecd8d91.jpg

SOURCE: My 40 inch Polaroid LCD tv screen won't come on

Hi

Thanks for using FixYa. From what you have described it seems that you might have a backlight and/or an inverter board issue with this TV set. It could also be due to the inverter circuits for the backlights. The inverter is the power supply source for the backlights. There could also be a screen driver problem; if it is then you have to change the entire inverter board. All this is only recommended if you have some kind of expertise for checking the internal circuitry of the TV as these units have high voltages running even when the set is switched off. The cost to change the inverter board including labor would be around $250, if you get this done by a professional. Please revert back for more help.

Toshiba tv 40rv525u has started to change channels


My TV 40RV525U changing channels, menus itself for few months ( I use antenna).
my son tried to stop the channel scrolling by enter weird number into the channel to stop it scrolling such as 555, 777..
later, it turn on off by itself and unable to hold on a channel
I call Toshiba customer service and they ask money $25 for troubleshooting but I denied since I do not want to waste money and time.

Now, I found how to fix it myself.

In my case, something was wrong with the signal comes from the button control on the left side of the TV.
========================
What I did
========================
unplug the power cord.
Remove back cover.
Look into the motherboard ( biggest green at the center).

First, I disconnect a connector on the motherboard come from the IR board that receive the wireless signal control ( meaning the remote is disable).
I turn on the TV, press on Menu button on the TV side. Menu is still scrolling.

I turn off TV, disconnect power cord and connect the IR connector back to the motherboard.
I then disconnect the nearby connector that comes from the side control buttons.

Turn on the TV by remote, press menu button on the remote to check. The menu stays.

DONE.

I use electric tape to seal off the connector and let it hanging there.
Close the TV back panel

I have been watching TV for 3 nights without menus/channels scrolling.
NO AVAILABLE red message when watching DVD is no longer existed.

Hope this help someone else.

Toshiba TV/DVD Combo Model MD14H63


I have the same problem with this model as Guest, who posted on 01/03/2008: power on, red light, immediate shut-off. The sticker on the television says it was manufactured in April 2007. I think there should be a warranty on it; I suppose I'll be calling Toshiba soon if it doesn't start working. Maybe important to note for any potential buyers, as well.

Here is where I found the remote code (1256) for the TBX-2000AF and it has many more codes for Polaroid models. Good luck (copy and paste this link) http://polaroid.custhelp.com/cgi-bin/polaroid.cfg/php/enduser/popup_adp.php?p_sid=fPLB5Gzi&p_lva=&p_li=&p_faqid=2854&p_created=1116267791&p_sp=cF9zcmNoPSZwX3NvcnRfYnk9JnBfZ3JpZHNvcnQ9JnBfcm93X2NudD0xOTk0JnBfcHJvZHM9JnBfY2F0cz0mcF9wdj0mcF9jdj0mcF9zZWFyY2hfdHlwZT1hbnN3ZXJzLnNlYXJjaF9ubCZwX3BhZ2U9MQ**
