Question about RCA Scenium D34W20 34" TV

1 Answer

Need service manual

The TV works OK but after a while it shuts down and the green power indicator blinks nine times continually. Push the power button and the TV turns on, but then shuts down again after 10-30 minutes of playing. I'm thinking something is overloading the power supply. Possibly bad capacitors+?-

No sir it probably isent a power supply problem as in these sets it wouldnt act like that. First thingm to check since you say your a service tech, is in the horizontal output check and see if the horiz. output transistors shorted. If its not then check a small coil off the base of the horizontal output transistor. its really the base drive coil so take it out and scrap off the ends BOTH ENDS and reinsert and also resolder the horizontal driver transformer. This may or may not fix your problem But if it dosent order if you think ther sets wrth it the flyback transformer as this is a big problem in these sets if the for mentioned things did do the trick. follow the kit instructions that come with the flyback transformer!! Dont take any short cuts. Make sure you do take out the horizontal output transitor or at least unsolder all the leads when tesating it for a short. Good luck

This could cause a problem, because modern TVs and most other entertainment electronic goods, have a small kind of computer chip, but there should be a Reset button probably inside the set! If you feel confident about computer chips you may be able to find the button by tracing the circuit.(Disconnected from the mains). Another idea is if there is a small button cell or battery inside, then try disconnecting it for a day. Good Luck!

SOURCE: TV turned off by itself, now wont turn back on!!!

It has gone into protection mode. This is caused when a short circuit is detected by the power management system inside the tv. Try a hard reset: Unplug the power cord for a full 4 hours; then try it again and see if it will clear the protection fault and reset it. If the reset does not help you will need to have a tech look at the set and take voltage measurements inside to determoine which section of the tv has failed and what components will need replacement. The cost of repair is always over $150 and could be much more, depending on the specific parts that need replacing. for example, if the convergence ICs have burned out the repair is around $350. The flashing of the standby light may mean something, but I do not know the diagnostic code RCA is using; most RCA models do not have any diagnostic blink codes in the set. Hope this helps. Let me know if I can help further.

Followed Terryfic's solution. I am a DIYer and managed to order the part, desolder the old one and solder in the new one. However, when I turned it back on I got a black screen with sound. Hmmm, saw the adjustment screws but was hesitant. Ended up turning about 10 degrees one way and presto chango... Saved a $1200 upgrade to HD for a $30 part! Thanks

Most likely a bad flyback. It's a cheap part, but service people are even having a harder time getting ahold of one since they are failing often.

My kids were watching the tv when it shut off. When I got home I turned it on and green light flashed about 100 100 times now the red light flashes continuous. Tv still not coming on.


Hi,

The Standby/Power light of the TV blinks when there is any internal malfunction in the TV. The self-diagnostic function of the TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue.

Few examples are given below; some of the issues may be resolved without the need for service.
1 blink / 2 blinks / 5 blinks: - This indicates that there may be a power-related problem with your set.
3 blinks: - This indicates that there may be a power-related problem with your set. The set will need to be serviced to allow a technician to determine the specific issue that needs to be repaired. If the power light flashes three times in sequence in a Lamp TV, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
4 blinks: - This indicates that there may be a back light or lamp power problem.
6 blinks: - This indicates that there is some kind of audio problem with your set.
7 blinks: - This indicates that there is a temperature problem with your set. Please check to make sure that the air vents on the sides and back of the set are not blocked or clogged and there is adequate ventilation around the television. We recommend that you check and clean the vents periodically to make sure the set receives adequate air flow. If the problem continues, the set will need to be serviced.
8 blinks: - This indicates that there may be a video-related problem with your set. If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.

If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.

If the issue continues to occur, service may be required.

The tv wont power on and the green timer light continuously blinks. I have unplugged the the tv and also hit the reset button.


...OK to begin troubleshooting this. Unplug the set and leave for 1 min then plug up and leave for 2 min push the power button and let light blink for 2 min.... now push and hold at the same time the MENU and DEVICE buton st the same time. this is the self diagnoses feature ... the lights should link then pause then blink again... this 2 digit code will help narrow it down. Also have you check the lamp yet?

SONY KV35S40 Light blinks continuously when power is pressed


hello there,

Many of the later model Sony TV’s have a built in self-diagnosis function. If the timer/standby indicator is blinking, this could be an indication of a problem with the unit. The diagnostic blinking will occur automatically with no action required by you to engage it.

The timing of the blinking you see would be as follows: two to nine blinks, (depending on the fault), about a third of a second apart, then a pause for 3 seconds, then the two to nine blinks about a third of a second apart again.

Universal remote wont work with this TV


Questions: Who is "Sansui", the digital box ? or the TV? Is the "digital box=remote control"? turn on what you want to control.
Face the RC face down or away from TV,or whatever you want to control. Usually:: push & hold TV & SEARCH button until light blinks, two, three times? FACE THE TV and put the code for the [TV=Sansui ?] You said #189 try 0189 [zero,one,eight,nine]
2nd) TV power ON!,....HOLD down (and if you have a SEARCH) button and the tv power button on RC, two or three blinks, push up arrow once, press power button for TV on RC, nothing!, continue...up arrow, power button. when the TV turns off, you have found the code,. YOU MAY HAVE TO DO THIS 50-150 TIMES because the RC is looking through EVERY code!
