Depending on your Toshiba model this may be an issue with the hypermodule. When it fails it will make the TV zig zag looking. One quick test is to see if your picture-in-picture window looks normal. If so the hypermodule is the issue. You can google Z1234TV to locate parts.

I am a TV tech and have had experience with this type of problem on many sets...So Far the only trouble is the 2 output ic's stk392-110 which should be replaced with the upgrade stk392-180..All three Color Amps are within these ic's for both horizontal and vertical convergence. Sometimes a resistor or two will burn out as well because of the short in these ic's. Be sure to be extrremely careful unsoldering and soldering and use good heat sink compound and fasten securely to the heatsink metal. Manual convergence calibration may be necessary after the ic's are replaced. First try Touch Focus after the ic's have been Properly replaced. This repair should be done by competent personnel and takes about 3 hours because of dis-assembly and re-assembly time. I am writing this because i have seen on this site mis-leading info. i come to these sites myself to verify part numbers and to see if there have been additional complications such as complete shut-down.

Make sure you didn't bridge anything, knock anything off the deflection board you shouldn't have. All the resistor values on both sides of the STK match up, and most importantly Labeled all your plugs properly and placed them in the right spot, because if they are switched, you'll get a convergence issue. Make sure the fuses are still good too and that all the terminals that all the plugs go into have good solder joints.
Also, there is a voltage divider.
Make sure that none of the wires got loosened when you pulled this plug. (Particularly the ground wire) Let me know!

You have a problem in the high voltage section of you television most likely one of the driver out put chip on the CRT board plugged directly into the back of your Cathode Ray Tubes if not check the the horizontal and vertical driver chips if they are getting extremly hot this could be your problem

Hello,


You can repair it, it is repairable, the problem is power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Hope this will helpout in solving the problem....

Hi,
Double vision/ picture problem occurs due to failure of convergence output ICs in rear projection tv and it is common problem of projection tvs.
Please replace convergence output ICs in tv to solve the issue, there is convergence repair kit available for $70 on This Site that has required parts/ ICs, instructions about how to replace ICs etc for a handy person.
Hope these info will help.
Thanks.

there are 3 low ohmage 2 watt resistors
for each stk chip, did you change those?
with-out those it may very well look worse!

there are a few shops that can physically repair these. I have personally repair a few. but however...it is very very tricky... it requires some very trick soldering to some very small componets...toshiba was replaceing so many of these they gave instruction on fixing these. it involves replacing 11 very small micro capacitors.... like i said very labor intensive. my shop generally charge 250 for the repair. just depend on who you get. WARNING this is the kind of repair that the technician can easly do more damage than good so get a respectable experince tech to facilate this repair

Replace both of your STK ICs, they are big black ICs STK392-110s use 120s or 150s CK all of your 1.8 ohm resistors. Mats Electronics has STKs
