Question about Samsung Televison & Video

1 Answer

I have an LCD TV- LA37R8, purchased about two years back, and hence out of guarantee period. Last week, I found that the power-suppy shown by the red light indicator was not responding either through remote or to the push switch right above the indicator. The screen "alive light" at the bottom, shining even when TV is switched off was also not showing. I called the local cusstomer service, @91-79-30308282 -complaint ref. no.8407609683 on 30.09.2010. A technician visited my place , opened the rear full panel of TV, and either he was not conversant with the circuits or mechanism, he just closed the rear cover saying that the TV requires replacement of some circuit boards which have got to be got from Delhi. The request to Dlehi wwould be made on 4th. and we might get the part in a week or so!! Please help me in his matter and send a knowledgeable Engineer and not one not even knowing English or technical terms!! Please do not send half-baked Technicians who might damage the TV by rough handling and not conversant with the circuits.

Todays TV repairers can only replace entire boards

the right question to ask is
does LCD as a company provide after sales parts for your TV
or their board circuitry information to TV repairers or the general public

you may find LCD have no parts support
TV makers only want sales of the new TV produced


otherwise an oscilloscope and lots of time is required to track down the faulty diode or capacitor or micro processor

SOURCE: Power Surge damage. Suggestions on which part to replace.

I would start looking at the power supply, it's usually a separate board where the a/c line plugs into. In many cases i have seen that the problem you described is from a damaged power supply, sounds like something is shorting causing the power supply to continuously come on and off. I would first check the capictors to see if any of them have blown, usually cylinder looking and sometimes you'll see an X or a K at the top of the cylinder, if it's blown then the top will be bulging out instead of being flat. If all those look good then there is probably a short somewhere else like in one of the transistors, if so you'd be best to just find another power supply board to replace.

SOURCE: Red noise or flicker on bottom half a plasma screen

The old saying that a pictures is worth a thousand words could have been looking at this one... If the lower screen had been streaked in B&W or bands ran completely through the picture Old Drummer I would suspect the logic board also but that's lower y-board failure.

SOURCE: Bottom half of the screen is black on Samsung HP-R5072 50 in. HDTV Plasma Television

It does sound a lot like a buffer board problem, Just which one is the question. Sometimes it is in fact a connection issue. But 1/2 of the screen missing sounds like maybe connection between the 2 buffer boards. It could possibly be the panel. If that is the case. ITs over for that set. But i would suggest first calling samsung and asking them to extend the warranty for 90 days or so. Sometimes they will do this for nice customer such as yourself. 1-800-SAMSUNG. Let me know how this turns out first then we can proceed further if needed. Good luck and keep me posted. Sincerely Jay

SOURCE: Red power indicator light is blinking

The flashing light indicates a short circuit inside the power supply circuitry. This type of repair is not a DIY without a multimeter, desoldering iron and hand soldering skills. I repair these power supplies, if you need further info write to jah2mil@hotmail.com

The timer does not turn the TV to the right feed


If the TV timer is set within then it will restart in the same channel as when you connect the power to the timer the whole power is shut down and so the memory is lost on the last attempt. Hence the TV will start back on the default setting unless there is proper back up on the memory.Please check if the TV timer can be reset to solve this issue or the memory must be checked for fault to retain last settings.

My RCA TV (Model L32 WD 22) was purchased almost 3 years ago. Just in the last week, when I attempt to turn the TV on (with our without the remote), it turns on (green light) and then immediately turns...


had a very similar situation with my Phillips 42 in. LCD TV.

Here was my Problem. The Power Supply Board. I opened it up( Warranty was Expired) and found several faulty capacitors on the PSB. Its pretty common. Major Electronic companies were sold faulty capacitors that fail in 2-5 years instead of 10-20 due to a lack of preservatives. It wouldn't surprise me if you have the same problem. TV will work fine for a few years and then just fail completely or slowly deteriorate.

Here are the solutions
1. Have it Repaired
2. Check for faulty caps and if you find some(budged or leaking) you know you have located a problem
Remove the board and replace the whole thing.
3. If you have some soldering skills you can replace the faulty caps.
Caps are very inexpensive, under a dollar in most cases. I replaced 4 for about $5.00

Hope this Helps.
Good Luck

I have a panasonic plasma th46pz80u. Last week


On Panasonic 32LX TVs this is a known fault, repairable by a firmware upgrade. John Lewis in the UK sent out an engineer under their free 5 yr TV guarantee and completed the firmware upgrade for me. The only other store to compare with them for price and service is Richer Sounds but I believe you now have to buy the warranty for 10% of the purchase price. This problem will persist unless the upgrade is completed. For those of you in the UK, I would insist the seller repairs the problem under the Sale of Goods and Services Act as the TV is not fit for purpose without the upgrade.
