UPDATE: Samsung TV TXE2545 Bottom Half of Picture

Hi,

Thanks to everyone for your responses. The only part I had to replace was the TDA8350Q. I tested the caps, some of you suggested may also need replacing, but they were fine. The other thing I did was solder several joints that had fine cracks due to thermal cycling.

Before you type your password, credit card number, etc., be sure there is no active key logger (spyware) in your PC.

If the only part you replaced was the ic, plan on replacing it again in a few months.

Did you install the Samsung required modification kit and all of its parts for the vertical ic failure in that set?

No he did not... Its amazing they ask for info and dont take it. This was brought to his attention but all he changed was the IC.

The kit is a collection of capacitors and zeners (I think; I've been away from this for a few years), a factory-recommended modification.

These guys have it.

The kit specifically is suppose give the ic a larger buffer with its range of operation to prevent premature failure. Most will last a few months to a year and a half if only the ic is replaced.

Most customers figure it is not worth the effort to take a 'junk' brand tv like that back in for a second repair after that kind of time frame.

I think the kit is a separate entity, but as I said, it's been awhile.

Samsung actually is/was good about its parts supplying. I don't know if there's a difference between a $4 non-Samsung part and the Samsung-supplied part either. Depends on the source, I suppose.

You have to be a member to access the download area of the techassist site. Well worth it for a technician, IMO.
