    I looked at the board pretty close. The only spot I seen that was obvious was the loose connection where the attenna housing mounts to the main PCP. it appearedto be just the mounting that came loose. there are still three solid to the board. I did not think this had any bearing on the problem. I called a repair guy trying to get info and he mentioned a depression board? does this sound like a viable solution? I unpluged all cables and plugs to make sure there were good connections. I think i may take the boards out again and re inspect. Can you pinpoint me to the correct circuit board to look for trouble. there are three. main power, Depression? and the main PCP if thats correct. I have now been getting blips of color lines red blue green that turn into the full blur cross diamond pattern. the banging of the board still corrects the problem temporaly.

    Hello I have new news regarding the problem with my TV. The problem is fixed. I took the advice I recieved about hte circuit board and looked over it very closely. I found that some gel had leaked onto the circuit board and coroded two wired on the board. once I cleaned the mess off the board and put it all back together. The TV works fine now. I believe that some of the cooling gel around the green tube leaked out causing the problem. I hope that this will help someone else.

Is great you have already found the place to hit and get the picture back,is a loose conectiont that need resoldering before it gets worst or damages something,be ateentive were you hit and flip the crcuit board,the broken solder joints should be easy to spot. If you are not too familiar with tv service seek the help of a servicer and tell them what you do to make it work,the repair should not be xpensive since you already diagnose the problem.Good luck

    Even if only one of the mounts is loose can give you problems,it could be the one that conects the ground to the other three,it should be resoldered regarless,resolder anything that does not look right.You already know you have a loose conection.

I get blury pictures

Possible that the CCD is a suspect. Try and allow the camera to be switched on for a long time, keep free from moisture or near a lamp to dry.
If not best is to take a referral for consensus without tampering without proper jig, spares and tools.

Red and green curved lines when the screen is dark

Your convergence board is going out. this will have to be replaced. i would take a look at the main logic board as well. it could have minor point breakage.

TV, RCA MOD # F19424, CTC 203U5, Picture blury

Focus and Screen. The focus control may help, just like focusing a set of binoculars or an old camera. Watch the picture on the TV, using a mirror can help and make an adjustment until the picture is as clear as you can get it. If it still is not clear it may mean that your picture tube is weak.
If you can avoid it, don't touch the Screen control. If you have, let me know and I can advise you on the proper way to adjust it.

Mitsubishi big screen blury

In all probability the picture is fuzzy too, its just harder to notice. This can be as simple as an adjustment in the back of the set. Carefully remove the back and look for the flyback transformer (part with large red wire coming out of the top). The should be 1 or 2 controls on it. One should be marked focus. Adjust that to get sharper focus.

Let me kow if that fails to resolve the problem.
