SOURCE: D20 Diode value on Motherboard.

Contact Dell support. Tell them that you were told by a tech (that has repaired many of these problems) that you believe you have a motherboard with leaky capacitors (do not mention the burnt out diode, just tell then it no longer boots). After much interaction with Dell technicians, it turns out that dell has extended the motherboard warranties of most of their PC's including laptops. I know of two people so fat that have had Dell warranty repairs done, even though the system was out of warranty. Once they hear "leaky capacitors" they will advise you that even though your unit is out of warranty, they will replace it. Hope that helps! Best regards

as your h/output got defective due to short circuit.proceed as follows. isolate h/output section fom power supply& check power supply output is ok as you know high output may give such problem. when it becomes ok, check hor.section 1 h/output 2 cap & diode connected in eht winding. 3 ptint short near eht. 4 at last eht tranf. 5 if it is ok re connect h/output supply. put on set. your que AFTER CHECKING I FOUND A DIOD(MUR460L)SHORT.I WANT TO KNOW THE FUNTION OF THE DIOD AND THE EQUIVALENT DIOD FOR REPLACE (BECAUSE MUR460L IS NOT AVAILABLE IN OUR LOCAL MARKET). 1 Function of diode is to convert AC TO DC 2 you can use BF159 or BF157 as equivalent.

I could find a place to get a free download.
Check HERE but you have to pay for a download.
Or you can check this site for complete assemblies for your TV.

Why come white vertical line on my t.v screen in center?


You said "I checked vertical output line from main ic pin 23 found correct"

But the problem is "Horizontal Output Line" Try that.

WHAT IS THIS PROBLEM R805 RESISTOR 33 Ohm BURNING how this solvation sharp tv?


Vertical output IC shorted. Replace it. Before replacing it, check all the associated components connected to its terminals for failure; especially for any zener diodes for short. It is most possible case. Refer its circuit digram [schematic diagram] for more details.
Contact any service technician.
If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

NEED TO ADJUST VERTICAL PICTURE


Replace capacitors CX2105 (35 volts 220 Mf), CX2110(35 volts 100Mf), C2104 (50 volts 1 Mf), resolder resistors RX2115, RX2116,R2118,R2119. You will need to also resolder the vertical IC. I think this IC location is IC 2200, its been sometime since I repaired this one.Do not short the pins together with excess solder. The values on the cap may not be exact. Please use the cap value that is removed (remove and replace one at a time). The locations will be correct! This will remove the horizontal lines or bars across the TV screen. You may as well replace capacitors in the horizontal deflection area. By now you have bad caps there. The locations and values are, CX3218 (160 volts 2.2Mf), CX3205 (16 volts at 100 Mf) CX3413 (50 volts 22 Mf) and CX3416 (25 volts 100Mf). Thanks for asking and show all hands of support.

Hi my TDA8350Q IC keeps burning out in my[ GE 25GT538 25" TV] ....can u tell me the cause of it...?????...an how to repair it...thanks...ps email...greene-b13@hotmail.com


Hi greene_b13,
Check you vertical yoke for shorts.
Make some re-soldering around the vertical section circuitry.
Check the diode around the vertical section circuitry for shorts.
Replaced all electrolytic capacitor in that section.
Thanks for visiting Fixya.

hi there, is the single line horizontally or vertically? if horizontal line, you do have a vertical section problem, check some parts at vertical section, the vertical ic, the power source of vertical section ie diode & resistors. ty

I see only horizontal line on TV Samsung CK-5339ZB


h/line is due to vertical section failure. 1 reduce brightness as you will get h/line due to vertical failure. 2 check v/section for loose contact or yoke connection. 3 check supply to vertical section. 4 check associated parts in v.section 5 at last check for vertical ic. resistor R410 CONNECTED TO high voltage transformator T444 is low value resistor. .5ohm to 10 ohm. it burnt again due to short cht in vertical mainly due to ic. hope this will help. as per schematic diagram go to www.serviceinfo.com

Horizontal White Line


Sounds like something is getting hot causing voltage loss or drive pulse loss to the vertical IC. Maybe you have a bad solder joint. Try tapping the circuit board around the vertical section. A capacitor could be heating and opening up. Stargazer Also you might try using circuit cooler spray and make the problem show up.
