When turned on picture was unstable (Jittering) for some time. Now when turned on the power indicator light comes on then blinks. No operation or display. I can't locate a repair for this unit in...


Depending on your Toshiba model this may be an issue with the hypermodule. When it fails it will make the TV zig zag looking. One quick test is to see if your picture-in-picture window looks normal. If so the hypermodule is the issue. You can google Z1234TV to locate parts.

Concaved shadow


this is because of the magnetic interference, you better isolate the TV from the devices producing heavy magnetic interferences like Speakers Microwave, Cellphones and Cordless phones. Then go the main menu in that you will find setup option , in the setup option go to the picture setup you will find option called degauss just click on that, the screen will flash for a second and everything will be alright. Frequent degaussing is not advisable as it reduce the life of the projection tube.

Zig zagged and flickering screen


The surface mount capacitors in a module called the Hyper Board have gone bad. The repair is fairly extensive in that the board must be desolderd from the chassis and then taken apart and all the electrolytic capacitors must be changed. The task is time consuming and not for a do-it-yourselfer. The average repair cost would run around $250.00.

RCA D52W20 - turns on and off, blue screen, tech said need picture tube


It does sound like the tube, have the shop use a tube restoration machine to rejuvinate the tube, and replace the eprom to try to correct the no power down situation.

RCA D52W20 - turns on and off, blue screen, tech said need picture tube


It very well could be the Blue CRT shorting out. However the not shutting off is not a symptom of the tube being shorted that sounds more like a signal board issue rather than a picture tube, as the signal board can cause all the symptoms you have described.

My tv gets zig zag lines on the screen


Hello luckyone1,
According to your name you get one lucky fix..not two

OK, OK ...That was funny
What do you meant by zigzag line? Do they look like what we would call herring bone. lines going sideways? Please let me know. If this is the case, I have never been able to solve that problem. I am very close with the tech over there at Samsung. We spent hours on this problem. We changed Complete main board. We also changed Power supply. The problem maybe coming off the Yoke or a somewhat defective picture tube.

Please post reply if someone did correct such problem

Best regards

Distorted picture


when you say distorded, is it like a 3-d effect? or more of zig zag type lines in the picture. If there are color outlines like a 3-d effect, then you are having a convergence preakdown, and are going to need to have the convergence IC's replaced. if the problem is the piture is zagged edges and zig zag, lines or a smearing effect, most likly it is the PIP modle is going bad, and even if you dont use the PIP, the video still goes through that module. If it does not have a PIP feature, then there are bad capacitors in the sweep power supply and the problem will get progessivly worse till the set wont come on anymore. Hope this helps. Good Luck
