Open Question

Polaroid Flat screen TV. Turn on the set and no picture. Blue indicator light indicates the set is active, but no picture. Try to turn off and the blue light stays on. I then unplug and plug back in then try again. Sometimes the picture will then come on, most times I have to unplug and replug about 5-6 times then picture will come on. When it comes on, there is a buzz that fades away after about 10 seconds.

SOURCE: Picture then fades to blue.

I just fixed mine. I read other posts that suggested this and it worked. On the front of the set at the bottom of the speaker cover are 2 caps, one on each side. Remove those caps to find 2 screws, remove screws and then remove that cover. Behind that is a panel with 4 screws and remove it. You will see a box with 6 knobs, 3 on top 3 on the bottom. Top are focus and bottoms are voltage to each lamp. Blue lamp is left screw, green lanp is middle screw and red lamp is right screw. Counter clockwise lowers voltage(very small adjustments. So if your screen is turning blue turn the left screw just a littleat a time. I also had red and blue lines on my screen so i turned them a little as well and they are gone. Give that a try, it worked for me.

Hello......
First reduse the G2 voltage for the blue c.r.t,and watch if the unit works for longer period (offcource blue colour will be not present).After reducing G2 voltage to blue c.r.t still behaves the same than c.r.t is faulty and you have to replace.
Pls count the red led blinking when it goes off,incase it goes to std by mode.

I have a polaroid 42 inch flat screen and the screen is solid blue when i plug my cable in it is black I can here sound but no picture it is a 2007 module tlx-04240b


Make sure all the connections are correct, a "blue" screen indicates no-signal, black indicates some type of signal is getting to the tv. good luck Julio milleniumtvsvc@gmail.com

Lines on the screen


Are they thin, white lines running east to west? If so, they are called retrace lines and indicate that the screen settings for the picture tubes is set too high or there may be a mal-function of the CRT driver circuitry. Try adjusting the screen controls which are located behind the front grill of the TV behind an access panel. Once you remove the grill and access panel, you'll see a small control assembly the has two sets of controls. Three for adjusting the red, green, and blue focus, the other, the red, blue, and green screen controls. To adjust correctly, put the TV on an unused input(dark, blank picture) and adjust until there are no visable retrace lines or color in the image.
