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

1 Answer

Now power 1-9 blinks

I tried your suggestion of checking all ribbon connections (man there are a lot of them!!!) to no avail...I also checked a fuse on the board right where the power wires plug in but it was ok...I called couple local shops and they want $175 to check it out if I bring it in and $250 if they have to come and get it and take it to their shop, plus they said it would be between $400 - $500 to fix as that is what the average price for an RCA (thomson) projection screen has been. At that rate I can almost get a new flat screen...any other suggestions before I call AmVets and have them come and get it??? I sure will miss it!!!! Thanks for your time and help!

I see so many people here with nosound /picture issues:


1. If sound main fuse/s are good.
2. If no power or standby light check fuse, standby power supply, and look forany signs of damage you can see (burnt parts etc)
3. Almost all these SETS troubleshooting consists of checking voltages andtrying to narrow problem down.
4. Be safe and if do not know what you are doing do not open set.


1. RE: fuses---if a blown fuse is found get a good replacement (not the Genericones from like Radio Shack). Many fuses used are special even aside fromamperage. Don't put a higher rate amperage fuse in the set for any reason.

2. RE:power supply: if total dead aside from main fuse set uses Standby powerand main power supply (some standby is on separate board but most are combined.

Here aside from checking fuses you want to examine all the filter caps to seeif any are puffed up or buldged in some fashion; I attach a photo: top shouldbe (silver metal) perfectly flat and have no brown material coming out on topor bottom---l can give you a description if needed here why they fail---too lowvoltage rating causes them (standby area) to overheat and fail in a average 1-2years= The standby is running 7/24 when set is plugged in.

3. Trouble shooting: It consists of the above and then at some point you haveto buy and try a board/s to see which if any fix the issue.

4. Safety first---no set is worth getting injured or even killed over.

Some additional suggestions:

Consider contacting company who made set for information to see if your problemis a common one that their data base has ideas about.

Also GOOGLE the model number with either "parts" "problems"or "manual" as a lot of information is available for free.
have here only given you the basics but they apply to most sets; depending on your skills if you have specificquestions let me know and I will assist as much as possible.

Model WT-46809 I am getting 1 blink, 2 blinks 5 times which means no error detected from reading some of these similar problems. TV still will not come on. (Timer light comes on, then immediately turns...

Glycol is a guey liqid that has a stick consistancy. It is used in anti freeze, (and so I have been told in cheap wines to give them body. Yuk!).
It is however corrosive and conducts not only heat but electrical energy.
It sounds like the power supply has died. On a machine of this age possibly due to aging capacitors and drifting value of resistors.
Check the poer supply secondary for leakind capacitors and the line output stage, especialy if it has a smell of selenium about it, the EHT system and splitter assembly.
Unfortunately, there may be parts no longer available from Mitsubishi but they should be available from distributors.

Sony grand wega KDF55WF655 6 red blinks

you can try these steps if this doesn't work I suggest replacing IC8002 on the power supply
Low HV Shutdown:
On the D Board.
Check IC8004/pin 7 should be 7.4v.
Check IC8006/pin 2 should be 2.5v if lower will trigger shutdown by causing pin 1 to turn on.
Check IC8006/pin 3 reference voltage 2.2v.
IC8006/pin 1 normally at 0v. If high turns D5007 ON which turns the latch circuit Q6532,
Q6530, and Q6527 ON and turns the AC relay RY6501 OFF.

NOTE: 6 blinks also can be Low B+ protection.

Unregulated 7.5 v from the power supply to 5v reg IC504 on the A Board. 5v to M Board Q2314
to CPU IC2300/pin 43. If 5v missing set will shutdown with 6 blinks

When I try to look up blink codes I'm getting conflicting info. On this model is the lamp on side of TV? If so 6 blinks is showing as lamp door error, the micro switch the lamp door makes contact with is either not closed all the way or possibly defective.You can try reseating door or check the switch and wiring connections coming off it. You could try temporarily by-passing the switch by making your own short across the plug it connects to.
If the lamp mounts in front 6 blinks is a defective thermal fuse.The fuse is mounted right next to the lamp.From the back you can disconnect the plug for the fuse and check for continuity if its open its bad.

No power

Check the ribbon cable connections between the boards to insure they are correctly seated as a 19 code usually means
Chassis detection, which means its not detecting a valid chassis usally the ribbon connections are the cause of that.
