Repeated convergence problem or something new?

I have had my 43PP9202 for 3 years now and back in October 2006 I started experiencing these strange green and red hour glass figures on the screen after the set had been turned on for a minute. You could turn the set off for a second and turn it back on and the colored swirls in the picture would dissappear. That is until you turned the set on again the next day and it would start all over. I finally called a local repairman and had him come to my house and replace 2 convergence ICs (STK392-110). I have had no problems since this until just the other morning, the picture began to show the same green and red hour glass across the screen. Since I had dealt with this issue before, I turned the set off and turned it back on. I tried this several times and each time the set came back on with the same exact distortion on the screen. Frustrated, I left the room, determined to listen to the show that was on even without the clear picture. When I came back into the room, the screen was blank but the sound was still coming strong from my surround sound receiver. I did not think to see if the sound was coming out of the actual television speaker. I have since plugged the set back in to see what it would do and I get no picture, no sound, and a slight ticking noise from the back. Any direction you can give me that does not include taking a loan out to get a repair man back out here would be mostly appreciated (especially by my eyes, it's hard to read my guide channel on a 19 inch set).

Call the shop and see what the warranty repair on the last repair is,the convergence ic must have shorted again and now the set went into shut down to protect itself.

Battery light came on and 2006 dodge stratus makes a strange whirring noise. What is this? I just started last night

It sounds like the bearings in your alternator are going so it's charging your battery but no a 100%.

Color convergence "whacked out"/blue shadow to right side

Your TV most likely has a convergence failure. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem


  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Mits 55908 Convergence problem

Good Day, John;
It sounds like the Convergence IC's have poor solder connections, by re-soldering the convergence output IC's should solve your problem. The IC's are large and mounted to large silver "heat sink" with STK 392 # on them. Good Luck, big IRISH.

Daylight savings time adjustment

The solution appears to be common for all recent Emerson SmartSet(tm) radios (BTW it's not the clock fault, it's the law).

Remarkably Emerson foresaw this, so here we go.

Short version (may require three hands :-) )

DST start:
Press and hold MONTH/DATE and ALARM 1 buttons for at least 3 seconds until the display changes to something like "4 F" (Fourth month, First week) alternating with something like "4. 1" (April 1st, for 2007) or "4. 6" (April 6th, for 2008). While holding down the MONTH/DATE and ALARM 1 buttons, now press the DOWN or "-" Set button (3 times) until "3F2" shows (Third month, second week) alternating with something like "3.11) (March 11th, for 2007) or "3. 9" (March 9th, for 2008). Let go of all buttons and we are now half done.

DST end:
Press and hold MONTH/DATE and ALARM 2 buttons for at least 3 seconds until the display changes to something like "10 L" (Tenth month, Last week) alternating with something like "10.28" (October 28th, for 2007) or "10.26" (October 26th, for 2008). While holding down the MONTH/DATE and ALARM 2 buttons, now press the UP or "+" Set button (1 time) until "11 F" shows (Eleventh month, first week) alternating with something like "11. 4" (November 4th, for 2007) or "11. 2" (November 2nd, for 2008). Let go of all buttons and we are now done.


This should remain until either the lithium battery fails or Congress undoes its work.


BTW the Emerson addendum has a history error. The time change in the first Sunday in April and the last Sunday in October did not start in 1966, but in 1987. Before that starting in 1966 the standard was set at the last Sunday in April and the last Sunday in October. Except for 1974, when it was January 6th, 1974 (DST start) and October 27th, 1974 (DST end) and in 1975 when it was February 23rd, 1975 (DST start) and October 26th, 1975 (DST end). Before 1966, state and local governments had many different rules. Source: http://webexhibits.org/daylightsaving/e.html

Converange chip-Where can I order one

This is very strange coincedence it seems the more I search this problem the more people I am finding with the same issue. This morning Aug 3 2007 I turned on our Panasonic PT-47WX42C to find this convergence problem! (distorted colours-off alignments) I, like yourself Hultsie would love to get the schematic diagram for our unit and change out the IC(s) myself. If we work together I believe we can accomplish this task! Please contact me at [email protected] if you would like to give this a go! I certainly will try to exhaust all avenues before I part with hundreds of dollars for something I know I can service myself. Oh, the defective IC(s) will more than likely have the values you need written on top of the chip...once you know the ones that need changing your local tv repair or even panasonic (if there close by) will sell them to you.
