Question about RCA D52W20 52" Rear Projection HDTV-Ready Television

1 Answer

Have sound, lose picture. D52W23

After being on for a period of time (varies from several minutes to hours) the picture will dim drastically and within a few seconds fade out completely leaving only sound. Turning it off for a couple minutes restores the picture but the problem repeats eventually.

Turn set on picture is dark.. if I leave the TV on.. in several hours it's viewable.


I have seen several Samsung's including 3 that were only a few months old at the time where it was the lamp---one was so dim it was very hard to even see the picture or that the screen was lit.

Two suggestions here: One of course would be to buy and gamble and replace the lamp.

What I found in two of the three cases was when I removed the lamp the glass pillar inside it was "bent" at a angle from heat or a natural defect--in both those cases a new lamp cured this dim picture issue.

Set will monitor the lamp and if too dim may shut set off or even blink for a prolonged period of time.

If the lamp is over 2 years or age (average life) or was replaced with a non-Samsung lamp you are going to have to take the gamble to try another one.

Inspect the lamp---that pillar supports the filament and if bent the lamp is suspect at best.

My KP-51HW40 clicks off after running for a period. The red power light blinks when it goes off but screen stays dark. When TV is shut off for a while it restarts and runs fine. The "On"...


Hi,
KP-51HW40 shuts off due to incorrect white balance and blue arch lines is an evidence of that incorrect white balance. I hope tv standby red light would flashing 5 times then 3 seconds pause and again 5 times when tv shuts down.
This is rear projection tv that has three picture tubes (red-green-blue) inside to generate picture that projected at front screen. These three picture tubes must be drive with correct drive voltage to produce good picture of each color.
Solution for your tv problem is Screen Voltage adjustment that can be done easily if you are handy with electronics stuff repair.
Let me know your expertise level to guide you more and if you feel unconformable by tv repair then local tv repairman will help you to adjust white balance in tv.
Hope these info will help you.
Let me know if you have additional questions.
Thanks.

My RCA D52W23 won't turn on


The set is in shut down mode due to a fault detected in power supply/vertical or horizontal deflection circuits.
The common problems with this model that will cause the symptom you describe are bad power supply capacitors, bad flyback, bad HV cap in horizontal output circuit and cold solders especially under flyback area.
These are only the most common problems and it could be any number of other faults.
If you have electronic (TV) repair experience check the items mentioned, otherwise it's best to seek a qualified RCA tech for an estimate/service call.

your problem is no doubt in the stand by circuitry You will have to trouble shoot your set as this is a thermal issue and you will need to do the testing of the various components while it is experiencing the trouble to find the problem.
