What's your problem?Pioneer PRO-530HD 53 in. Rear Projection Television flashing red standby light

This and a few other models like it have one real common issue:

they develop from age and heat bad solder connections all over the power board (rather large board).

My experience with them is the fix usually is remove rear cover and follow power cord to power board (a lot of plugs to mark) and remove that board----then solder every single connection on the board which by the way has some special fuses on it.

Have a Pioneer pro elite 730hdi. When you try to turn it on (main power, not standby), the tv cycles from the red (standby) light with the normal click to the green light, then one second later, it cycles...


Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like, to buy a whole refurbish power supply board for the replacement.

Hoping this will help in solving the problem....

TV won't turn on, it has a blinking light on the power button

It seems that the power is reaching the power switch. The power switch seems to be at fault. If you can remove the rear cover to replace the power switch. Or replace the whole module as that would be easier.

TV keeps changing channels by itself

Either the channel up or down buttons on the tv are most likely stuck.

Convergence is off

Starts up with black raster, then shuts down with LED blinking 4 times
This is the micro telling you that the auto grey-scaling procedure has failed. Change resistors R909, R913 & R922 (180k, 1%) on crt base PCB. You will probably find that all these have gone high
Standby only
Check R101 (4.7ohm), TR102 (C6180) and C126 (47uF, 16V)
Tv turns on automatically. Power supply works well, +5V present but seems that CPU (7700) does not (no standby mode), no remote or control on the front of the set
After replacing CPU (TMP47C434) and crystal 1770 (4.0MHz) both control worked intermittently. Replacing transistor 7674 (BC548) solved the problem
Will not work, standby (red) LED flashing
C604 in the 12V line is bad
Int going into standby
Replace C454 a 22nF smd, located near the Frame o/p ic.

Re: standby mode???

No really the standby mode dosent mean the sets fried or unrepairable. It just means that the sets in a shutdown mode till a power supply problem is corrected. They have shut down protection when the power supply dosent regulate the b+ and if it didnt shut down it would give off tons of X type radiation. thats just a safty on the set. seek a pro to assist you in repairing the set. Good Luck
