I got a 50'' Toshiba projection TV and when i

I got a 50'' Toshiba projection TV (used) and when i turned it on i could hardly make out the image. After realigning the convergence ( with the crosses ) it has made it better but there is still jagged lines in the top half of the screen, and the entire screen flashes the odd time. The next day i turned the TV back on and the image was worse again, so i ended up realinging the crosses in the convergence menu, and it is back to better, but still has the jagged lines and the odd screen flash. Any help?

    The brightness is good. The picture is not dim. Movement seems good when doing the convergence. Only problems are

    zig zagging lines,

    When i did adjust the convergence to improve the image, after the TV was off over night, it seemed to reset all my alignment settings, so i had to do it again when turned on.

    Everything else seems to work perfect.

Will my toshiba tv bought in uk work in usa


There are two things you need to know regarding your TV.

Power requirements and broadcasting standards.

1:POWER
Look on the back of the TV and find the sticker or label that mentions the INPUT VOLTAGE.

If it reads 220-240V 50Hz then it will not work in the USA.

If it reads 110-240V 50-60Hz then it MAY work in the USA. At least you know it will work if you change the plug on the mains cable.

2: BROADCASTING
In the UK, broadcasts use the PAL system to display images on the screen. In the USA, broadcasts use the NTSC system to display images on the screen.

You need to check the manual that came with your TV to see if it is capable of receiving an NTSC signal. This signal is used in everything in the USA from PVRs, to DVD/HDD recorders, satellite systems, public access and cable systems.

If your TV meets the power and broadcast requirements then it should work.

Picture often flickers and image distorts every few minutes


The trouble is most likely in the Video processor. If the trouble looks like its tearing the video only from side to side it may be the line doubler circuit. Some of these boards are no longer available but a good TV tech may be able to componnent level repair it for you.

Generic Problem


You will need to replace or have the convergence ICs changed out. Not really a hard job and should cost you about 225 to 375 to have this set repaired. Good Luck

Color problem with Toshiba


Sounds like a problem with convergence, poss just requires new STK 392-110 ICs , may need a couple of resistors that go due to faulty ICs
