If anyone can offer a solution please feel free to let me know. I turned on my TV and it was blurry. It had no indicators prior to this occurrence. There are times that the TV will turn on and begin to look like it is OK and then over a period of 30 seconds or so it becomes blurry and stays that way. I'm wondering if it is something I can fix myself or is it something I will need a TV repair man to fix. Please help.

Re: Blurry GE 27GT616 need help on how to
The problem could be with your crt base socket, if you know how to solder well and can identify the components and have a knack in dealing with the internals you can fix this yourself. Base socket is the stuff that you connect to the narrow end of the picture tube, you will find a pcb and a plastic connector almost round in shape on that board. Desolder the socket (the plastic connector) and get a new one, exactly the same type and solder this back.

If you are comfortable on doing adjustment with working TV then take off back cover of TV and check flyback transformer, there you would see 2 control knobs, upper knob if to adjust focus. rotate it CW or CCW to obtain maximum focus on TV screen. Put back cover and enjoy.
Each projection set has focus controls in back, usually they don't move or go out of focus unless someone moves it, but in your case if you open the back you will see a focus block with 6 knobs 3 are for screen,I would highly recommend that you don't move this. Look for the focus and you will have to set each with the one color. Cover the other two and adjust.
The first thing to check is for loose conections,the problem is related to the high voltage but it can start in the main board with one component loose,when the high voltage is developed it goes to what is call the distributor block,a lot of sets have the focus and screen controls coming out of this block for each picture tube,this block might be bad but before we go to him we need to check everything is solid in the main board.If you are familiar with electronics you can remove the back cover and tap the chassis with a wooden or rubber handle to see if the set reacts,if it does you need to be atentive what area makes it react and flip the board to do some resoldering,If you are not too familiar with tv service you need the assistance from a servicer.Let Us know how it goes or if you need more information.
Sounds like theres a leaky capacitor in the screen drive circuit. I have seen this problem also be a gassy crt but was able to clean off the grids of the CRT with a crt/rejuvinator. It happens because of low emmissions in the tube and when white is on thats a mix of all the colors, so the tube works harder. I bet when you whatch a movie and the scene changes suddenly to a white or brite scene the pic looks a little washed out. If this is not the case then I aggree with the Pravin and try it on another TV just to be sure .. This is not a repair for a consumer to do, though however it is only a three year old set you stated, so there should be life left in the tube, so im kinda thinking a capacitor is bad. Seek out a yechnician to check this out for you as a TV is not a place to see it you can fix it or to exoeeriment with. Good Luck
There shouldnt be much in the focus system to go wrong as really there is nly the tube base and the flyback transformer. The usual for a TV is the tube faulty so its beyond repair. You could try the focus control, this will be on the flyback transformer. Back off TV, look for a heavy lead going to the dome of the tube at centre top and with eyes ONLY follow that back to the flyback transformer. On the side of that transformer is 2 screws, one near the top is the focus control. You will need a screwdriver to turn it and it usually has a seal to be broken. That will turn from say 8 o clock to 4 o clock no more, turn it up clockwise, try both ways. if it almost fixes but not quite it would be the tube.
