What is the Remote Model for TOSHIBA Colour TV Model 2168TIV


In my opinion, you should not have to give them the remote number, but you can look this up by contacting the customer service website of Toshiba, giving them the model number of your tv..and explaining your situation...also check eBAY for remotes.

I have a 36 inch toshiba tv model # 36A50 and i have black bar at the top and one at the bottom i only have approximently 3 or 4 inches of screen in the middle to watch. what would it be? that problem...


For one thing you have a vertical problem and since it got that way gradually you can bet that there is a bad capacitor in the vert. circuit(pump-up cap) as far as the price goes it depends on your local servicemen, i`m in canada and that sort of problem fixed at home would run around a 100.00$. good luck

This is a vertical circuit problem that is either bad connections on the vertical IC or a defective IC. If you can solder, you can fix this yourself. Look for a small flat IC attached to a heatsink with about 9-11 pins. It may be marked LA7837 or something similar. Try resoldering the pins first. If that fails to resolve the problem, replace the IC. There may be defective caps in the circuit as well, but those don't usually cause complete vertical failure. If the picture does not return fully, update this and we'll continue on to the next step.

Standard CRT Toshiba TV - 4inch tall picture in middle of screen...


Hi,

 

Not familiar with your actual model.

But a comon problem with older Tosh sets is the 2.2uf electrolytic caps from memory they are usually red there is 1 next to frame Ic & the second is near Psu.

Allso check frame o/p IC for dry solder joints this is easy to test for.

Tap the tv while it is on if the the frame suddenly pop to full size picture you know its dry joints so resolder frame IC.
