20 Most Recent Samsung TXH1970 TV Questions & Answers

Hello
There is some short circuit in the secondary side of the switched mode power supply section inside the circuit board. Now only the 5VDC is correct, as you see the standby light ON. The short is likely to the horizontal output transtor. Replace it first and see whether it helps you. If not line out put transformer is faulty, and should be replaced with same type and number..If any internal short occurs, the power supply protection system will activate, and shut down all other secondary power supply rails, as a protection to prevent further damage to more components, This is happening in your TV now. OK

The audio section of our TVs is often combined in a single integrated circuit. You can buy these with differing degrees of gain and power and some sets are built to sell at a certain price level so cost-cuts are made in areas like this. There is not normally any internal controls that can limit or raise the sound level.
What you might consider: Check front and back to see if you find the standard 3.5 millimeter 'headphone jack.'
If so, check at any department store or computer outlet for a pair of 'stereo speakers' intended for desktop computers. These are amplified by an internal amplifier in one side and the other side is plugged into the main speaker. These sets are small and cheap; often under $20 although they range upward to $100s as well. If you just want more volume, these will provide it, but the cheapest are no 'hifi' by any means.
The link below to eBay will show you a typical set of these with a 3.5mm plug and the power ratings are at least believable; many are not.

Hope your tv is three digit, 427,060,482,037,039,052,030,178,408,019,056,032,329,059,100,009,...hope this helps..

Sounds like there is a short in the TV. DO NOT try turning it on again. Take this into a TV repair shop. This could be a fire hazard.

Have to select antenna, video is for when you use a vcr or DVD input. Otherwise Video means you are using another source to dump into your set that you want to watch froma pre recorded source.

I encountered the same problem with a color computer monitor several years ago. Everything went green. The repair techies told me that's a sign that the power supply is going bad. You will not be able to adjust the color. You will have to either fix it or replace it. Hope this isn't a common problem with this model Samsung TV.

The TV requires a manual degaussing. Degaussing is the operation that neutralizes a magnetic field on the face of the tube that causes the color distortion. There is a coil inside the set that does this each time you turn the set on, but it's not strong enough to counter the field the magnet left behind. An external degaussing coil would clear this up, unless the magnet used was so strong it caused phyical damage to the picture tube (but that's unlikely). You could purchase a coil from any of several internet vendors, or call a TV shop in your area to see what they would charge.

(There are some techniques described using a small motor appliance like a hair dryer as a degaussing coil, but generally they don't work reliably. If you are really curious, a quick search using Google or another search site will get you links you can check out.)

get a universal remote it should work

bro you should take it to the repairer,No other options you have. it can't be fixed by doing anything accept changing it's screen or repairing it, if it's possible

Hello. You can check HDMI cable in this case. If you're using an HDMI port that's not working well or has been damaged, it could result in a darker-than-usual screen. If you switch the cable or change devices and the TV is at a regular brightness, this is the case.

It sounds like you might be dealing with backlight bleeding or an issue with the LED backlighting in your TV. This can sometimes occur over time due to normal wear and tear or manufacturing defects. If it started as a faint single brighter section and has now expanded to four, it's likely a hardware issue. While it may not be an easy fix, contacting the manufacturer's customer support or a professional technician would be a good next step to diagnose and possibly repair the problem. If you'd like, you can share the pictures for a more accurate assessment.

All I can advise is to take it to an authorised Samsung repair shop. A list is available on the Samsung web site.

The old yellow, red, white RCA cables are analogue signals, while HDMI cables only carry data. They are in no way compatible. You can buy active conversion boxes that will convert analog to digital, but simple cables cannot work

It can't be done. The Samsung remote will be single frequency for that Samsung device only and the LG remote for that television (or series) only. Companies don't make cross-control between makers easy. The only exception is cable and satellite boxes to allow their remote to also control the television.

These LEDs are very susceptible to static electricity damage. What happens when they get zapped is a tiny threading fault starts in the LED crystal. The aluminum contact metal starts migrating into the crack, makes it wider and longer, and eventually goes all the way through the LED and shorts it out. When that happens, the metal overheats and burns out the LED so the entire string goes dead. What this means for you is that the original LED may have been may have been zapped at the factory. The replacement strip likewise, or when it was removed from another TV (if it is a used part), or when you put it in. It should have been in anti-static packaging. You have to be very careful not to touch any of the circuitry on the LED strip, and make sure you ground your hand to the TV metal both before picking up the LED strip and right before connecting the strip to the TV. Better yet, use an anti-static wristband connected to the TV frame. It is possible that the LED driver for that string is pushing too much current, but that's not likely. You would probably notice that part of the screen is unnaturally bright.

Can you tell this power supply board zener doide value?

It sounds like your TV has a display issue, likely caused by physical damage to the screen due to the bend. Repairing a damaged screen can be quite expensive, often nearing or exceeding the cost of a new TV, especially for larger screens like the one you described. Here are a few options you might consider:

1. Sell it as is: You can try selling the TV in its current condition, clearly describing the issue with the display. Some buyers may be interested in purchasing it for parts or attempting a repair themselves.
2. Attempt a DIY repair: Depending on your technical skills and willingness to take on the challenge, you could try to repair the TV yourself. However, this can be risky and may void any remaining warranty. There are online tutorials and replacement parts available, but again, this route requires some technical expertise.
3. Professional repair: You could contact a professional TV repair service to get an estimate for repairing the screen. Be sure to weigh the cost of repair against the potential selling price of the TV after it's fixed to determine if it's worth the investment.
4. Sell for parts: If repairing the screen is not feasible, you could dismantle the TV and sell its components individually. Some parts, like the internal circuitry or casing, may still hold value to electronics enthusiasts or repair professionals.
5. Trade-in or recycle: Some retailers offer trade-in programs where you can exchange your old electronics for store credit or discounts on new purchases. If the TV is beyond repair, you can also look into recycling options to properly dispose of it.

Ultimately, the best option for you will depend on the extent of the damage, your budget, and your willingness to invest time and effort into repairing or selling the TV.
