No picture have sound

The picture screen shows only 3 colored lines bowed across top no picture and a greenish bow across the bottom no menues will show . the 2 stk convergence chips were changed a few months ago and it worked fine until this latest problem I have described.. I have a service manual but it is 90% schematics and gives no help troubleshooting.

    Ic's were changed at a shop.. I ordered 150's and will put in myself if it works I will rate the remedy suggested as excellent. for now I'm waiting on the snail mail for the chips as I live in the bush in a 1 street town.

    well I have received the new convergence chips I bought sony 392-150's instead of the 392 110's so that if it was the power draw and heat that caused the failure these would take the extra.. wall it took 10 minuits to replace them and when I fired up the 60"zenith there was no change at all it looked exactly the same as it was before I changed the chips. well 40.00 bucks down the hole I checked for cold joints and cooked components but found nothing , there has to be another answer does anyone have IT. thanks for trying so far ,no go.. I would rather wait until I get the set fixed to give a rating because a not good rating does no-one any good

Sounds like your IC's took a dive again. Did you change them or a shop? You have to also make sure that when you change the IC's that you put plenty of heat sink compound on the back of the IC's and do not use the cheapy IC's that you can get for 20 bucks or less as I have found they do not last. This convergence board should be available as a complete board. Good Luck

    It is now time for you to get a schematic diagram, a service manual, sometimes this is necassary as when the IC's blow so does a return resistor or an inline pico fuse. You need to make sure each IC has at leat 20 to 24 volts plus and minus on the IC. This is how a schematic or service manual will help.

Samsung TSL2793HF - Slight Right Side Pincushion and Horz Line Bottom to Top Until the TV Warms up

Yes, this is rare but I have seen it before--not fixable if it is what I think it is----It is what is called a Dome effect---the shadow mask in the picture tube is actually contracting and or expanding depending on temperature---

Directly behind the phosphor coating (the stripes that you see on the screen) is a metal screen--the holes or perforations in it line up with the stripes on the phosphor screen.

Some masks either have a material or a defect causing the dome effect----Not likely to be anything else---a Pin amp problem will not usually act the way you describe but a shadow mask inside the picture tube will act exactly that way.

Projection tv has 3 versions of what is on tv instead of one

Projection sets have two very common problems.

The first common problem is convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture
