LG TV Repair: 55LB5550-UY TV

It’s LG tv repair time again, at Bammel TV Tech Services. Customer brought in to us on May 23, 2018 his very nice 55″ LG smart TV for repair service, a 55LB5550-UY, with a complaint of “blinks, check out.” We put the flat screen tv in the service queue and prepared to perform our diagnostics.

LG Electronics is the latest iteration of the original Lucky Goldstar corporation. Founded in 1955 as Goldstar, during the rebuilding in the aftermath of the Korean War, they produced Korea’s first domestically-produced consumer electronics and home appliances. LG Electronics produced South Korea’s first radios, TVs, refrigerators, washing machines, and air conditioners. Bammel TV was for many years the authorized service center for Goldstar tv’s, and later for their full range of home electronics and appliances, including microwave ovens. We parted as friends, and we still perform occasional spot and request service for LG, on a case basis.

Together with Samsung, LG forms the “dynamic duo” of high-quality, low-cost electronics and appliance manufactures from Korea. The Koreans have totally laid waste to the giant and dominant Japanese consumer electronics firms, such as Sony, Panasonic-Matsushita, JVC, Toshiba, Sharp, Hitachi, and Mitsubishi. Japanese automobile dominance is not yet in serious question, but here too the Koreans have made serious inroads.

The 55LB5550-UY exhibited a full spectrum of 1080p grade LED-class hi-definition characteristics, including a 1920×1080 resolution with 120 hz refresh. Included were a range of connectivity optia, and good quality sound from two 10w speakers running Dolby’s digital decoder system.

After its time in queue was up, we benched the unit to the diagnostics lab of our chief technician, who made the determination of Backlight Fault: behind the display panel of modern flat screens is an array of high-intensity LED lights or lamps, and occasionally one or more of these will fail, leading to a variety of complications. In the past, we tended to quote for/replace only the actually-faulty lights, or the associated strips; but often other lamps tended to fail out. So these days, we’ve learned our lesson—we usually now replace all the LED-strips.

Summary: How we fixed an LG 55LB5550-UY TV

Our quote approved, we ordered and installed parts, and completed the TV repair. See this video for a full report and case study, from beginning to end-stage/final test, of how we fixed an LG 55LB5550-UY TV. For more examples of our art-and-science of TV repair, click here.

Samsung UN55FH6200FXZA repair at Bammel TV

Samsung UN55FH6200FXZA repair at Bammel TV

It’s TV Repair Houston time once again; in this case, Samsung UN55FH6200FXZA repair.

Customer brought in to us for tv repair service his nice 55″ Samsung flat screen tv, with a complaint of “long time to warm up, then flickering,” with some other associated issues. Check in date was 5/22/2018.

The Samsung UN55FH6200FXZA specs-page shows it’s a nice set, with 1980 x 1080 resolution and a 240 hz refresh rate. A good, solid smart TV, with two 10w speakers and Dolby/DTS-class sound.

We logged it in, shelved it; and carted it to the tech once its place in the queue was up. Our chief technician diagnosed the unit’s fault as due to primary fail of the main PCB. We completed diagnostics by 5/25.

From this point the admin/research/quoting squad gets involved, and performs standard database consultation and mining, plus associated vendor research to source the necessary part. In this case we came up with a repair quote both we and the customer could live with.

We developed our quote and, as is our wont, collected a special-order parts deposit to proceed. Customer approved our quote, and paid the supplemental deposit to order the main board on 5/29. We logged payment; created our internal Purchase Order; placed the part order; and waited with bated breath for the part to arrive.

We received the freight shipment by 6/4. We completed repair the same day—including a Special Video Shoot, for the Youtube channel and blog. Total turnaround time for repair was thus 13 days, which included the Memorial Day weekend and 4 weekend days, for a total work-day fix of 8 working days.

Here is a link to the Youtube video about this repair.
