T/V set ,LG MODEL NR RI 32CZ10RX (BEKO chassis V80.190-08) This set had a dry joint at the scan coil plug (horizontal pin 1) which had arced badly. After repairing this the picture was restored, but it was over wide and stretched on the R/H side, with pincushion distortion.T501 was found to be leaky, but a replacement made no difference. however, it runs very hot, Any suggestions?

I dont have its schematics but still can try to help you if you provide snap shots of pincushion area through email welcomejee@yahoo.com It just would be a try, I am not sure about fixing it.

Hi
Please check around vertical outpu IC for bad solder joints and you can try to replace the electolitic capacitors in vertical output line. Check if vertical plug (which comes from deflexion coils) is well attached in place.

I have an LG 26LB75 on start up it is White with a few black line going horizontal then it goes black any ideas?


This is a common fault as the set on ageing deteriorates in the connections. There is a high possibility that the components over a period of heating and cooling, tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs or poor performance.

The best way to check for loose connections is to tap lightly when the set is powered on , If there is change while tapping then it seems that there are DRY solder joints. Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points.

Sometimes the fault occurs when the set warms up, if so you can simulate the heat using a hair dryer on the suspected areas, try with the power supply, distribution, Processor controller, driver controllers on the A/V related sections. Also the use a FREEZE-IT spray can simulate the components to cool and show up the fault.

Based on the above method you must be able to locate the area of fault and solder the sections. Sometimes large IC's- ones with more pins- tend to have drying in some pins and so cause faults related to the IC's protocol. Have a rough idea of looking into the areas to reduce the time of probing.

Solder all the drivers of the panel.

No picture just one straigth line in the middle


If this is a horizontal line then the horizontal coils is not driven , It can be a silly fault of a dry solder joint at the pin corrrection coils, in the board, or a faulty resistor( open ) or a capacitor int his section.
if the line is horizontal then the vertical scan is absent and so it is failure of the vertical drive.
Solder vertical IC and sections, can be faulty IC or capacitors in this section.

My tvs picture keeps compressing into one line


If it goes to a horizontal line, you have a frame fault, usually caused by dry joints on the frame IC. Look around all IC's and components that are mounted on heat sinks as they are prone to poor soldering.
Likewise if it is a vertical line, dry joints on the scan coils can cause that as well as heavy components on the pcboard.
Hope that helps.

TV WILL NOT COME ON - TV Chirps when you plug it in


The F25432 uses the CTC203 series chassis. The most common cause of the picture being intermittent is poor solder joints on the small coil connected to the base of the horizontal output transistor. These cracked solder joints will eventually cause the horizontal output transistor to short, and the power supply will "squeel" when plugged in. If you have experience working on TV's then you can try resoldering the joints on that coil and checking/replacing the horizontal output transistor. If you do not have experience working on TV's then allow a qualified tech to handle it for you.

Ge 32gt740


The GE (actually RCA) 32GT740 uses the CTC203 series chassis. The most common problem in that chassis is a coil connected to the base of the horizontal output transistor comes loose, and the set may run sometimes and then it will shut off by itself. If you keep trying to run the set with the solder joints cracked on that coil then the horizontal output transistor will short out and the power supply will squeel when plugged in. Do not plug the set in if it squeels as this could eventually cause major problems in the power supply. The set needs a new horizontal output transistor and a good resoldering of the drive coil, drive transformer and all related parts. If you do not have experience in unsoldering and soldering electronic components in TV's then have a qualified tech handle it for you.
