Question about RCA P52929 52" Rear Projection Television

1 Answer

NO POWER, Yes blown fuse.

After hurricane Rita come through, and power had been returned to normal, the 5a 250v fuse was blown, replaced and blown again. Up until this point I had NO problems with the TV. Since then have looked vigorously for any possible/obvious component damage. Only one componant was visibly damaged (burnt), a 220ohm resistor, this was replaced, another fuse put in, only to blow another fuse. What am I missing? Help greatly apprecciated! RCA 52" Projection TV Model # P52929 Serial # 111651490 Chassis # PTK195S11B Mfg. March 2001 FYI: After Rita, this happened to nearly ALL electronics in my house, some I have repaired, others still troubleshooting.

    If I am checking properly NO short accross A/C. Does it need to be removed from board to check? What to check for?
    .22uf 250v-x2 (sound right?)-or- .1uf 250v-x2 (?)

Was this the 220 ohm in the power supply??? and if the 5 amp blew right away then it probably took out the bridge rectifyer with the power surge that comes alog with hurricane damage to the power lines as I used to live in florida and repaired lots of sets damaged from storms!! After you check the bridge rectifyers I would start looking to find any other shorts. First measure across the ac line with the fuse replaced but not plugedf in . If its shorted check what I mentioned before if its good after you replace the shorted parts you maybe in luck. need more assistance go to sams photo facts download a schematic and we will trouble shoot this together if you post it here so i can look at it. good luck

    Did you replace fuse before checking for short???Did you check across the main capacitor for short?? if no short there go to horzontal outpit transistor and disconnct two of the legs and measure for short there. Then if no short measure from collector to ground for short. Iv,e seen a dozen or so parts taken out by storm surges.

I have a Olevia 242-T11 and it has no blue power light, removed rear cover discovered blown fuse at power board, went to radio shack and found simular fuse 5A 250v but fuse keeps blowing out when powe


The fuse is always a protector and when it had blown a second time it is certain that there is a short or high current drain in the power circuit which exceeds the limit and so to prevent further damage or fire the fuse blows off. You need to just use a multimeter to check so as to confirm the short on the power supply unit.

Olevia 242fhd-t11 Has no power. Will not turn on


I am guessing that since you are checking other outlets that you are getting no STB light or anything. So you will want to start by looking at the SMPS on the unit and see if the 5A 250V fuse is blown or not. If it is blown then you can try replacing it but I would bet that it will just blow again. So you need to replace the SMPS

Can,t get it to turn on.


Does the red light come on? does it go green but no picture? Here are few possible solutions:

If you have no red light and you have a Megmeet MLT386 power supply, check these parts:

1) Swollen caps on the secondary circuit.
2) Blown fuse F1 (5A/250V) this is caused by a shorted FET at QA1 (20N60), you may also find that SMT cap CX23 is burned up (.001uf) which is in parallel with diode DA2 which may be damaged/shorted, replace these components.

If the power LED goes from red to green when powered up but no picture, then it might be lost +24VDC from the power supply:

3)Check fuse F2 (3.15A/250V, I put a 5A in), if it is blown, replace FET at QA2A (9N50C), replace QA2 as well (9N50C). Check SMT resistors at R233,R234,R235,R236 (.47 ohm). If open, replace with .1 ohm 1W or 2W resistor (easier to source). Also replace SMT transistor QF1 (2X4 or 2N4401 NPN transistor). And replace diodes at DS2 and DS1 (HER207), DS2 was shorted, DS1 was ok but I replaced it anyway.

I dont know as much about the Megmeet MLT169A, but it has similar problems and similar components.

4) I had to replace all of the capacitors in the secondary circuit (there are six in a 3x3 row marked EC9 (1000uf35V),EC10(1000uf35V),EC14(470uf35V) and EC18,EC19,EC20 (all 1000uf35V).

T.v. won't turn on


The following parts can be purchased at digikey.com or mouser.com web site. I am also posting all of the things I have found so far with these TVs.

Here are few possible solutions:

If you have no red light and you have a Megmeet MLT386 power supply, check these parts:

1) Swollen caps on the secondary circuit (may cause the red light blink problem, but also see below).
2) Blown fuse F1 (5A/250V) this is caused by a shorted FET at QA1 (20N60), you may also find that SMT cap CX23 is burned up (.001uf) which is in parallel with diode DA2 which may be damaged/shorted, replace these components.

If the power LED goes from red to green when powered up but no picture, then it might be lost +24VDC from the power supply:

3)Check fuse F2 (3.15A/250V, I put a 5A in), if it is blown, replace FET at QA2A (9N50C), replace QA2 as well (9N50C). Check SMT resistors at R233,R234,R235,R236 (.47 ohm).

OK for the Megmeet MLT169A with red flashing LED when turned on I found that IC7 was bad. This is an SMT component on the solder side of the power supply. It is a 4407P (P channel 30V MOSFET). For testing purposes, we jumped across it to feed +5V to the TV permenently instead of allowing +5V to go into standby.

TV won't turn onthe red light just blinks when I push the power button.


I think this might be bad/swollen capacitors, or something odd in the +5VDC circuits of the power supply, but I am posting all of the things I have found so far with these TVs.

Electrolux oxygen 3 fuse


The fuse on my ELECTROLUX Oxygen3's sumo board did have clear markings: F5AL250V - this is a 5A/250V 20mm fuse made by BEL FUSE, however, any other such fuse should work. The fuse on my board was blown (luckily, what caused it seems to be a glitch as replacing the fuse was all that I had to do). I got 5A/250V 20mm fuse from RadioShack and, expecting that this could happen again, I also installed a simple (5A/250V-rated) automotive fuse holder (also from RadioShack) (the only fuse holder that was available at a local store) and it works wonderfully now. Should the fuse blow on me again, I should be able to replace it in less than 3 minutes.

Durabrand rb-22j1a wine cooler----no power to unit at all after being plugged in, all fuses are good.


I had this problem, no power, no light. It was the power supply output fuse. It appears to not be blown, but a continuity check across the fuse shows an open. Unsolder and replace the 5A, 250V fuse with some locally available Radio Shack parts (holder - 270-739, fuse 270-1071). Access to the power supply board is on the rear, remove the screws on the plastic plate, including the one hidden under the QC sticker. While you are in there, clean the fan and the aluminium fins on the heat sink (cools the Peltier device).

If your fuses are not blown, look at the electrolytic capacitors (the black or blue round metal cans with the aluminium X on the top) to see if they are bulging. Replace any that are bad (a common problem in switching power supplies).

Hope this helps,

The fuse which you have used is of correct rating 250v/5A, the switching regulator of the SMPS primary section is faulty, so the fuse blows of continously

Fuse blown


the fuse will always blow if there is a shorted component. the horizontal output transistor may be the most likely culprit, if you are not a technician, have it service by a qualified one.
