Mitsubishi TV WD-65735 won't power on after replacing DLP chip. Only getting blinking green Timer light, which turns off.

The WD62825 has a Digital Module located on the left side of the chassis looking at it from the rear of the set. It's housed in a metal box that can slide out of its holder after removing the trim screws.
The module has its own power supply board and there are a group of 16v/1000uf caps on that board which commonly fail causing the constant flashing standby light. Further back on the module is a small board about the size of a matchbook called the E2P module. Its SMT (Surface Mount Technology) caps also commonly fail which can cause the same symptoms. Techs can tell whether the E2P has failed by simply removing it, hooking the DM back up and trying to power the set. If it powers on the picture won't be much good - but at least you can tell what's keeping it down...
Back to the caps on the pwr board. If they've failed they usually will buldge visibly on top. And ESR is almost not necessary. In any event that's the nuts and bolts on this model.
Is it a job for a layman? Yes and no - you might strongly consider a tech if you don't feel comfortable removing all the connections that the DM has with the signal board. There are about six - multi-pin - wired connections to unplug and then sliding the DM out of the unit and carefully removing the screws and latching to take the DM top cover off...
Hope this helps.

The lamp is either defective, not connected properly to the wiring or plugs (careful alignment required on the two connections), wrong type bulb, or the front panel is not replaced properly to trigger the panel sense switch (lower right side of panel)

This Chassis has been known for a slew of Capacitors failing throughout many of the Circuit Boards. The best way in my opinion to fix the set is to send the Chassis Assy to Mitsubishi for them to rebuild it. Some folks have has some success in replacing the bad Capacitors in the Power Supply, the DM Board, and the Format Board to get the set to turn on. These Capacitors are identifiable because the tops of them are bulging up.
It is a difficult set to work on and disassemble, this is Mitsubishi's Customer Service Number in case you need assistance. 1800-332-2119
I hope this helps,
