Since this is a CRT based set, there is no lamp to replace. The set is in protective shutdown. This means that a problem was detected and the set shuts down to prevent further damage. Perhaps one of the most common faults is the horizontal output transistor. If you have any experience with TVs, you might be able to fix this yourself. If you are not comfortabel working inside the set, expect a parts cost in the $50 range plus hte local labor rate for the repair.

It could be a fanning problem or a lamp problem but it also might be from inproper wiring on the inside of the tv which can cause some wire to burn others making your tv not have any setup. that can be fixed by rewiring the main circuit through the power generator on the inside of the tv.

Put lamp cover back in its place as 3 times blinking light shows lamp cover has not been fixed.
Lamp cover is first thing that you removed to replace lamp in tv, make sure it is fixed securely in its position.

HI,

Did you try a hard reset? unplug all the cords for 4 hours and then plug it back.This will restore the factory default settings.If this doesn't help then you will have to get it repaired since it is switching to protection mode to avoid any further damage to it.

Goodluck..

I have a RCA D52W17 rear projection T.V. When I turned the power on the green light flashed 3 times then shut off and now it won't go on at all.


Hi


Thanks for using FixYa. 3 blinks in your RCA D52W17 rear projection are caused due to 3 capacitors (CP114, 120 and 150) which are located on the deflection board. If any of these capacitors goes bad you’ll have to replace them with the exact same ones. Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thanks

TV turned off and now the power light blinks three times


Very common problem. 3 blinks means the convergence circuit has failed . Heres a link to the repair kit for your model which contains both convergence IC and the feed resistors and the kit has step by step instructions with pictures so you can easially do the repair yourself.

WD-62725 Need to reset to start


Good Day;

When TV will not turn on press the menu & input buttons on TV's panel, hold for 5 seconds. Count the blinks, eg; blinks 2 then pauses then blinks again. It should do this 3 times.l With that information respond back.Or the d-board is bad.

Good Luck.
