Question about Samsung HLN5065W 50" Rear Projection HDTV-Ready Television
I have sound but no picture. I was watching a program and the picture just disappeared. What caused this and how can this be fixed? The lamp is working. Please see original question at bottom of post, then follow upward.************************************************************************LATEST:I meant to report that now that the TV won't turn on anymore, the Lamp and Temp LED indicator lights blink when I'm attempting to turn the power on -- and stay that way until I unplug the TV. Please advise. Date: [Wed, 19 Nov 2008 21:42:46 -0600] From: firstname.lastname@example.org To: email@example.com Subject: Follow-up Questions E: Follow-up...I'm not "satisfied" yet. Your reply encouraged me to ask follow-up questions before "accepting." I didn't expect that I'd have to "reject" in order to ask follow-up questions. If I messed up by doing this, I'm sorry. The "ask more questions" instructions weren't clear to me, obviously. I was hopeful to learn of the most common failures that I might investigate further. The internet and owner's "quick guide" sure led me to believe that replacing the lamp was the likely cure (the TV's about 5 years old -- can you tell from the Model #?). The problem is NOT turning it ON -- I just get sound, black scree, and the timer, lamp and Temp LED's flicker off at the same time. Again, the manual suggests this might mean the lamp needs replacing, so I did. There IS a problem with turning the TV OFF -- I have to unplug it from the AC outlet in order to turn the TV off. If I get a ohmmeter, how can I check the new replacement lamp to see it I got a "dud" replacement lamp? (I actually suspect that might be the whole problem). Once I tried everything again (just now), I couldn't get the TV to come on -- just the Lamp and Temp lights were flashing. Again, I can't turn it off either (without unplugging). When I tried the new lamp last night and just now, the TV would turn on (audio only) AND I got a fairly faint "humming sound" (didn't sound right, for sure) that lasted only about 5-10 seconds. From that point on, I couldn't turn the TV on anymore, either. Can you please suggest another thing or two to try...or perhaps help me determine if my new lamp even works?! You mentioned that I might like to know about how much a repair service call was likely to cost. Can you provide the ballpark estimate you eluded to? Thanks a lot, Dan Losey Lake Charles, LA ---- firstname.lastname@example.org wrote: > Thank you for asking your question on JustAnswer. Sorry to heap about the TV problem. Heat is the enemy of electronics, and these sets operate hot. By unplug the TV for an hour or more you did a power reset. If this power reset does not allow the TV to turn on component failure is indicated. These sets are assembled using the wave soldering process they are known for having cold solder connections. The safety circuitry shuts the TV set down when it detects a problem. This model of TV has over 3,000 parts which include millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Integrated circuits and transistors can go bad. This can cause other components to become defective, which can have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again since if the parts that caused the failure to begin with are not replaced. The only way to know for sure what is causing the problem, which parts that are no longer within factory specs and for proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment and the skills to use the test equipment. I wish I could tell you there was a quick fix or button to push that would fix the TV but that is not the case or the solution needed to get the TV operating correctly. > > If you wish to repair it yourself what type of electronic training do you have? > > What type of TV test equipment do you own? > > Do you own and know how to operate an oscilloscope? > > If you decide this is not something that you can do would you like an idea of what the cost to repair the TV will be? > > Should you require further clarification, never hesitate to ask. It would be my pleasure to clarify my answer to your question. If after reviewing the above information, you have additional questions, I will be glad to answer them.

I procurred a replacement lamp and swapped it out to no avail. Any suggestions?
I understand the continuing problem. The blinking LEDs indicates that the unit is still in protective mode since it still detects a hardware fault on its initiation diagnosis. Initially, may I suggest referencing this page for similar concerns. This would serve for the time being rather than listing probable faults and possible corrective actions. I am of course assuming that you have and familiar with a DVM as well as working with live sets. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

I really cant understand your problem . It seems you have used some forum for your problem and you got some suggestion . But whats your problem . Just only provide the information what you need or what is your problem .
From above information i think your tv doesnot show any picture and sound too is not working .
If thats your problem .
Check the fuse and check for any faulty capacitor on the circuit board .
Also ensure that there is no bad solder on the circuit board .
This is just initial help .
Post back proper details pertaining to your problem to get proper solution
