Question about Toshiba 42H82 42" Rear Projection HDTV-Ready Television

1 Answer

Squiggly Lines at Power On

Started getting squiggly vertical lines near the top of the screen at power-on. Lines disappeared in 10 to 20 minutes. Now these lines extend to the whole screen and don't go away for about an hour after power-on. Even then some line motion is seen at the top of the screen. Machine is just over 5 years.

    Thanks. Does this suggest replacing the power supply too? Look forward to hearing from you after you research a bit.

Generally speaking, this type of symptom is caused by AC hum leaking throught the power supply. This can be due to a bad filter cap. Since this clears up after a while, I'd start by looking for poor solder connections in the power supply area. If you can, check the caps in that area as well. I'll research this a bit and try to get you more details.

The tv has red images, I cannot get the red convergence line vertically to straighten, it is squiggly, the horizontal is straight, and the blue and green lines are both okay

the 43h71 has a pair of convergence ics that commonly go bad and cause this problem. replace original stk392-110 with stk392-120. the upgrades have a collector rated at 4 amps vs the 110's 3 amps and should be more reliable.

also know that they hyperboard in this set can cause squiggly lines throughout but will not affect the convergence.

My rear projection tv has squiggly horizontal lines in the picture. Sometimes when I turn it off and then turn it back on it goes back to normal but it is steadily getting worse. Any suggestions would be...

I have seen this on quite a few Mits's as they are getting to that age. This is usually related to bad caps in the signal path. I could go into more detail if I knew the exact Model Number (it will start with WS or VS) Example VS-60609. But the caps are usually near the 5v regulators.

Hi Tammy, Yes it can be repaired, most companies charge about $250.00 to repair the convergence circuit. Have them check to see if the SRS/WOW 3D pcb has been modified also!

Check the cabel TV or antenna conection first. And check the tv with a DVD player or VCR too if work thats a problem.

Some TV forget the settings after a power lost, so try to set the stations again.

Mitsu. 1080 Problem -- Green squiggly lines

if no one answered then hear my thoughts.  odds are it is 2 ic's
I say that because that has been the problem with mine,
except it was the red.  it happened in 2000 when I bought the tv
and just now.  its going to cost me about 400.00 to have someone fix it.  I'm getting it fixed because it's been good to me. I watch dvd's vhs's and laser disks and feel it has plenty of life in it.

good luck
