Question about Televison & Video

1 Answer

Mitsubishi WS55711 TV. 'm OK with a a soldering iron and have done similar repairs in the past but I'm far from an expert. I had a convergence problem and have installed a new convergence chip and replaced two bad resistors. First time I reconnected the set came on but the convergence screens didn't show the grids. I discovered I missed connecting a wire and tried again. Got the grid but had two problems: 1) I could align all but the top and bottom right corners which remained pretty badly warped and 2) Powering off and on required me to readjust the convergence. I removed the board and discovered some loose solders on the chip, resistors, and pico fuses (I disconnected to test a few). Fixed the solders, replaced the board and this time I'm back to the issue of not being able to see the grid. I don't see any wires obviously disconnected. Any idea what I might have done or which components are responsible for displaying the grid (I don't remember which wire fixed it last time or more accurately the wire I think it was is attached)?

Since you said replaced a chip, I presume it was the one STK-393-110 which is used in some models--most of their sets use two chips------I know these sets very well.


I have a offer for you---if you have Yahoo IM we can chat there and maybe find your problem.

Westinghouse ld-3235 picture goes in and out connections are good stops after 30 minutes or so,only 5 wks old


I have the same tv and had the same problem.
If picture appears when you slowly hit back of the tv, then the solution is quite easy.
1-There are 2 small lids on the back of the tv, open the one at the top with using a screw driver.
2- there is a connector on the top, make sure that it is connected well.
As far as I understand there is somehow a connection problem or maybe result of oxidation or something.... 5_3_2012_9_06_22_pm.jpg5_3_2012_9_06_40_pm.jpg5_3_2012_9_06_54_pm.jpg

What is needed to repair my panasonic tx32pl10 with a colour problem


The minimum requirement to repair your TV are soldering iron, solder wire, soldering paste, desoldering pump, digital multimeter, knowledge of electronics & service manual of the TV. If any smd is to be replaced you need soldering station. A digital storage oscilloscope will be more than good.

I have a nokia 1110 model ,phone is ok but the mic is not working ,what should i do now tell me the solution


If there's no internal problem like circuit or ic issues, your problem will be fixed after replacing the mic. You can get the mic from any mobile repairing shop or from mobile spares shop. There's a specific mic for your model, but if in case, you can't find one for 1110 model, then get a universal mic (small), you'll need a soldering iron with soldering wire and paste. If you now how to use mobile soldering iron, go ahead but if you are not good at it, i would suggest you to get it done from a mobile repairing shop. A small mistake can lead to permanent damage and unrepairable.
Good luck.
Thanks for using FixYa.

Three colors bleed on screen and shadows reduces to portion of top screen model mitsubishi 60'' 2001 how to fix


** Caution! Hazardous voltages inside. Technical experience required.
This is a convergence problem. You will need repairs done. likely will cost $200-$600 depending on parts, service call, labour, etc. The convergence ICs are not particularly hard to change but you need good solder skills.

Distorted picture that curves up at the bottom of the screen


My 9 years old Mitsubishi WS-55857 had the same problem (distorted pictures) for couple of months and I was about to buy a new plasma TV. But, I found TvRepairKits.com and I decided to give a try before buying a new TV. I received a convergence repair kit in two days with web site info for detailed instructions with many picutres to explain the process. When I had questions and Ed was very prompt to answer my questions thru the e-mail. I never done solding before, but I am moderate handy person. I spent less than $100 and three hours and my TV picutre looks stunning. I went thru advanced convergence process after I repalced the convergence chips and replaced RCA video cable with better quality and my TV picture looks as good as brand new. Thansk ED for your help!

Tv turns on then turns off


Sounds like you have the very common failure of the high-voltage transformer. It transforms your house voltage into a smaller contrinuity for the system circuits. You can get one at tigerdirect.com but you will need soldering iron & solder, ohmmeter, voltmeter and if you have never done this before, then a service/repair manual would be handy as well.
