KV36XBR400 fragmented picture horizontal overlapping lines

http://www.photofactondemand.com/set#4736

chk vertical amp /vertical drive i/p from oscillator/power to it/power to vertical amp/chk dry joints-hot area/look at vertcal amp capacitors-swelling etc

I would look for intermitent solder connections on the small horizonal driver transformer as well as other HV Componets.(HV Transformer etc.) Also solder up the Vetical output IC. These have been common causes of failures. I would not use the set until these have been checked and soldered. If you don't, a massive failure of the hoizonal circuit and powersupply will occur.
Hope this helps,

In most of the case, the problem is a defective LCD panel, if is it, there is not worth to fix.

Due to vertical section failure horizontal line apprears. You did not mention about picture. Green horizontal line means with picture or without picture. With picture means there is some leakage. Without picture only singe horizontal line means vertical section totally not working. Particularly green horizontal line means maybe leads to jungle ic failure. Please mention your simptom clearly what you get and what you will not get both video and audio. It will be helpful to answer. Based on your question this is my small information.

Well, if you still had a good picture before it happened, I would repair it.

This problem is usually a small part in the horizontal circuits. The service charges may be high, but the parts cost should be low.

This is a large heavy set, If you take it yourself to a shop you will save on the service call.

Basic repair for skilled TV repairman = solder connections on
vertical output IC.........Can be done in home.....T.

you probably aren't checking this posting out anymore, but maybe someone else will see this and it can help them.

i was having the same problem, did a search and found this solution. worked like a charm!! go here:

Hello, maybe there is a contact error in power supply or the deflection stage. If the resoldering does not help- here are some possible solutions: remedy Replace flyback location LP04. Entered for KV32S22 /SONY (Chassis) remedy 2 Replace IC351, Q602, Q601 (2SC4834M), R607 (1R/0.5W), R622 (10R), IC641 (SI3090CA) and Q502 (2SC5148). remedy 3 Replace tuner. remedy 4 Replace R607, Q502 and IC601. Entered for KV32S22 /SONY (Chassis) remedy 5 Replace regulator IC, R607, check C609, C610 (0.68pF) and C613 (0.0022pF/500V). remedy 6 Replace horizontal output transistor (2SC5148), IC601 (MX0841) and R607 (0.1R). remedy 7 Replace IC1701 and IC601. remedy 8 Replace Q501 (2SC5148), R607 and resolder horizontal driver transformer. remedy 9 Check and replace horizontal output transistor Q502 (2SC5148) and IC601 (MXD8411AB-F). remedy 10 Replace shorted R607. Also check T501 and Q501 for dry joints. remedy 11 Replace C608. remedy 12 Replace Q602 and D648. remedy 13 Replace Q502, Q601, Q602 and R602. Entered for KV32S22 /SONY (Chassis) remedy 14 Replace D626 (6.2V). remedy 15 Replace IC801 and R607. remedy 16 Replace horizontal output transistor and the associated damping capacitor. Check flyback transformer and SMD microprocessor as well. remedy 17 Replace R639 (4.7R/0.250W) located on G board in standby power circuit. remedy 18 Replace D600. remedy 19 Replace C502 (0.47uF/50V). remedy 20 Check D655(1N4937), D657 (1S1834) and Q601 (2SC4423). remedy 21 Check D606 for leakage. remedy 22 Check yoke between vertical and horizontal windings for S/C. remedy 23 Replace Q601 (2SC4834MNP), R607 (0.1R) and C517 (2.2uF/250V). remedy 24 Replace R611.

I believe the cable guy is correct and I will suggest you call for professional help now,if you try to use it like this the problem might become expensive.
