20 Most Recent Samsung HCN436W 43" Rear Projection Television Questions & Answers

chips should be stk-392-020 or 040 and entry to the convergence menu is mute 181 or 183

Unsolder both chips and look for pico fuses on that board going to the chips---if set comes on with chips out of the circuit then one o f them is a bad chip.

Hold your ps3 power button for 5 secs (it will beep several times). then reset the video settings. hope that helps.

What is the Model number that is printed on back of TV?

Hello,

Remove the TV wire from the wall plug, wait for about 30mins for TV to settle, plug it back into the wall and power on the TV and see if problem will persist.

If problem persist then problem is either from a dying lamp or a power problem. If the blinking light it green, then it means you need to replace the lamp, but if the blinking lamp is red, it means your TV is having a power problem.

Red blinking light on your TV is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.

All these can be checked on the power supply board.

But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Regards.

Hi Edwards,
The main reasons of your problem is the bulb which is already came to its end. The unit will automatically shuts off when it sense a bulb failure. Replace the bulb and your unit will back to normal again.

Hope I helped you.
Have a nice day!

If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

there are three oil filled bulbs in the back of your tv , dont try to remove them yourself or change there around the £300.00 pound mark its a sighn there going ...

TRY TO USE REMOTE TO POWER ON

Sounds to me like the focus unit has expired or a poor connection on the EHT line.
Check for EHR arcing and don't forget there is in excess of 28 THOUSAND VOLTS there, so be very carefull indeed!!!
If the RHT unit requires replacement, there are several wholesalers who will supply one on description. Just Google the part description or part number, that is useually printed on it somewhere.
Hope this helps.
