Question about Samsung HL-T5687S Television

Open Question

I have the Samsung HL-T5687S DLP tv. A few months ago, I noticed it would not power off. The only way to power it off is by unplugging it. It also will not switch off the HDMI input to go to another input. It also will not pull up the menu either. It's out of warranty by 1 year. It still functions. Luckily it's stuck on the input setting that we use to watch TV through our HTPC. But I can't hook up anything else to it (xbox). I've contacted Samsung and they just referred me to a local service company who wants $100 just to come out to look at it, which is reasonable, but then they want another $125 + whatever the part will cost. Not know what part might be the problem or its potential cost, I'm not yet ready to drop the $100 to start the repair. If that part's going to be $300, then I'll just leave it until my $1600 TV is junked. (so, so sad).

SOURCE: Horizontal lines on Samsung Plasma

Hi,


The most common cause for the loss of picture is a bad Horizontal Output Transistor (HOT). but I would suggest you get a detailed estimate. I think that this would cost you about $60.

The horizontal lines means the vertical amplifier or deflection system has failed. There are over 100 components in this section and any one of them, or most of them can be at fault. However, the most common failure is the VOT or vertical output transistor (which is often buried inside a chip).

The repair will cost around $150 plus or minus.

FEW TROUBLESHOOTING STEPS YOU CAN TRY:

ONE: Do a hard reset (just to make sure there is nothing in the coding that is fowling things up). Unplug the power cord; leave it disconnected for 4 hours. That will restore everything to factory defaults when you power it back up.

TWO: Do the "whacking test" by banging your fist on a few strategic places to see if there are any cold solder joints or loose wires acting up inside the set.

If the above steps don't solve ur problem then I suggest you to go for a repair if you don't have any knowledge of repairing it.

Goodluck...

SOURCE: Samsung LN26A450 LN26A450C1DXZA won't turn on

I had the same problem with my Samsung LN26A450 LCD TV. I found the following YouTube video http://www.youtube.com/watch?v=Mm51C_RDIZE titled "Samsung TV Repair - Part 1 of 2) (also watch Part 2 of 2) which shows how to easily fix the problem. The problem is bad capacitors on the power supply board. My TV had seven (7) bad capacitors - all 7 had dark stains on the ends from leaking electrolytic fluid and one (10V 2200MFD) was blown with bulging ends. I ordered 7 new high-temp (105 degrees C) aluminum radial capacitors from DigiKey.com matching the Temperature, Capacitances and Voltage Ratings for each damaged capacitor that I removed. I followed the instructions in the video except I used desoldering braid ($3.99 at RadioShack) to remove the solder attaching the bad capacitor leads to the power supply board. Once you wick up the old solder from all sides of each lead wire using the desoldering braid, the bad capacitors are easily removed. Total cost of repair including soldering equipment was less than $50. Thanks to “The Professor” for posting the video and saving me $400.

Our picture disappears on our DLP HL-T5687S


Check this site to get more details about the faults to DLP TVs. Check it by search to your brand name and model number to its search box. Might be a lamp problem. Not sure. Check this link.

When I turn on my HL-T5687S, the screen remains black and there are 3 dots on the lower right hand side of the panel?


My TV is (same model is doing the same thing). The manual shows that the 3 blinking lights indicate "LED may be defective. Please contact a certified technician."

Note: When I power my TV off (unplug) and back on, the TV's left indicator light is solid for less than a second ("Stadby state") then the right light blinks ("The picture will automatically appear in about 15 seconds") for about 15 seconds. This pattern is repeated numerous times (I think it was 5 times). I believe the TV must be failing some power-on test. Aftere failing 5 times it gives LED may be defective indication.
